There's a new 500 series computer in the room. After the original Edge 500 and its replacement, the 510, Garmin is introducing this Edge 520. And just because it's in the 500 range, it's not going to be a simple or basic device. On the contrary, it automatically becomes the most feature-rich Garmin computer in the entire range. At least for now, as other devices will be getting some of the new features in the 520, but they'll have to wait. In the meantime, you'll always have the Edge 520.

It's true that I owed you this test for a long time, but it got stuck in the drafts until I was finally able to steal a few hours here and there to get it done. I always like to clarify the origin of the devices. This time the Garmin Edge

of the test has not been ceded for the test, but I have bought it directly from the store with the intention of being able to start my tests as soon as possible. And in the same way I also want to make it clear, as I always do, that the tests are carried out completely independently, without any external pressure of any kind to make up my opinion about the different devices.

Remember that if you want to show your gratitude for the tests I perform and want to help support the site (and as you can see, to have proof as soon as possible), you can buy your Edge 520 through the links I provideThat way I get a small commission for each device (or any other item you buy), which is what allows this website to continue and covers some of the work I do.

Now that that's all clear, let's get on with the test. Everything you wanted to know and no one had told you about the Garmin Edge 520.

The good

  • With physical buttons, the touch screen is not always the most practical (especially with gloves in winter or rain)
  • Possibility of navigation with maps, both road and MTB
  • ANT+ FE-C for roller control
  • Includes front stand
  • Possibility of advanced training (intervals, etc)
  • Connect IQ opens up many possibilities
  • Compatible with Strava segments

The bad

  • Memory limited to maps of your nearby region
  • The navigation is of routes, it is necessary to load them previously
  • To continue with the navigation, it is point to point and does not indicate specific turns (for example, turn into the main street on the right). It indicates the turn on screen but you should see on the map where it is located


Unpacking

The presentation of the Edge series is a little different from what Garmin does with Forerunner watches, in this case it is a box made entirely of cardboard, where on the front you can see a picture of the Garmin Edge 520. Below you can find the text that indicates that the size shown in the picture is the real one, so you can get an idea of how small it really is.

With a size of 4.9 x 7.3 x 2.1 cm, this is a significant reduction compared to the model it replaces, the Garmin Edge 510 (which measures 5.2 x 8.6 x 2.4 cm). In other words, the size is reduced in all aspects (width, height and thickness). And with this reduction in size comes the consequent reduction in weight, from 80 to only 60 grams, a 25% less.

Despite being smaller, the screen size is increasing. If before the screen measured 4.4 x 3.5 cm it is now slightly larger in height and width, measuring 4.7 x 3.5 cm. An impressive job by Garmin. Garmin Edge 520 As you can see, Strava is a very important selling point in this new Edge 520. Not only does the logo appear on the front of the box in a very visible place, but the screens that can be seen on the back of the box are also very important. The inclusion of Strava's live media in Edge 520 is a selling point that Garmin has continually repeated, and as long as the exclusivity agreement with Garmin lasts, it will remain so.

In addition, with the purchase you are entitled to enjoy three months of free use of the premium version of the sports social network. Garmin Edge 520 I'll stop telling you stories and go to the device itself. When we open the box we can confirm that, indeed, the size advertised on the front is the actual size. garmin-edge-520-3 The computer is not the only thing inside the box, there are also other essential accessories, such as the brackets (three are included) and the transmission and charging cable. Ah! And the instruction manual, which a priori is not very important, especially because everything you need to know about the Edge 520 you will learn by reading this article.

This is the content of the standard version. If you buy the pack version, you will add a speed sensor, a cadence sensor and a pulse sensor to what you see. Not a bad deal, of course.

The Edge 520 has a total of 7 buttons, three on the left side, two on the right side and two on the bottom. The screen is not touch-sensitive, which some may miss. The buttons are good size and guarantee a firm touch, so even if you wear winter gloves you'll be able to use the computer without much trouble. On the left side you can find the illumination button (which will turn the device on and off), just above the two scroll buttons.

Garmin Edge 520

At the other end are the menu access and selection confirmation buttons, along with the return button. In this case, unlike Forerunner units, the return button is not used to mark laps.

Garmin Edge 520

To mark these laps we have the lower left button, the lower right one will be the one you use to start and stop the recording of the activity.

Garmin Edge 520

Inside the box you will also find a strap. What for? The strap is used to add a safety hold. It is fixed to the handlebar and in the event that the Edge 520 falls out of its holder in a pothole, it will be secured by the strap and will not fall out. Something that on the road should not worry you, but on a mountain bike and depending on the trialeras can happen.

Garmin Edge 520

The sync and charge connector is located at the bottom of the device, and is protected by a rubber cover. The resistance is IPX7 so you won't have problems on rainy or snowy days.

Garmin Edge 520

So much for the device itself, now let's get to the brackets.

Included accessories and supports

Garmin is generous and includes three brackets to put our new Edge 520 in the place of your bike that you prefer. This place is usually the handlebar or stem. The type of bracket used is the typical quarter turn (not to be confused with the quarter turn, that's something else). This is the one that Garmin has used for all their cycling devices for quite a few years now, so if you have already had a Garmin computer you will have a few of these at home.

First of all you will find two small supports. On top of the supports you can see some rubber bases on which they are mounted, to avoid scratches on your handlebar or stem. And below them two sets of rubber bands that are the ones you will use to fix the support in place. You must choose the ones that best fit the thickness of your handlebar or stem.

Garmin Edge 25

The third support included is the extended front support, which is placed on the handlebar and attached to it by means of a clamp and an Allen screw. It places the computer in front of the handlebar, at a point that is more convenient for viewing information, especially in the case of road bikes where your forward position will appreciate having the computer at this point, rather than on the stem.

Garmin Edge 520 - Front Mount

Since Garmin has not changed the type of support, it is easy to find proposals from other manufacturers with different configurations, such as K-Edge support for Garmin Edge and action cameras

Garmin Edge 520 - K-Edge Support

There are a multitude of supports, so it will be easy for you to find the ideal configuration for you.

Configuration and data screens

Before you start training with it you will want to set it up to your liking. The first thing you will find is that you must select the type of activity you are going to do.

Garmin Edge 520 - Activity Selection

These activities are the default ones. You can modify them to your liking, or delete them and start from scratch. To do this you can go to the settings and activity profiles. The settings that can be made in each profile are as follows:

  • Name
  • Color
  • Data screens
  • GPS mode
  • Map
  • Alerts:
  • Automatic functions
  • Notification of commencement

The color of the activity will help you to identify which one is selected on the main screen, as well as to give color to the whole menu.

Garmin Edge 520 - Menu Colors

Garmin Edge 520 - Menu Colors

Garmin Edge 520 - Menu Colors

But without a doubt the most important section is the one corresponding to the data screens, since it is the information that will be shown on the screen while you are training. Up to 5 different data screens can be configured with between 1 and 10 data on each one, so it will not be due to lack of information.

Obviously, the more data on the screen, the smaller it will be, so you must find the point where it is easy to see the information at a glance and have all the information you require. When splitting the screen, first align the data vertically up to a maximum of 5.

From then on each row will be divided into two columns, from the bottom to the top. This organization cannot be changed, so you cannot have the row divided in the middle or at the top.

Y por supuesto, la selección de datos posibles es muy, muy extensa. [table id=83 /] [table id=84 /] [table id=85 /] Uff, creo que no me he dejado nada. Como ves, infinidad de datos para que puedas configurar la información que vas a ver totalmente a tu gusto. Y como es evidente, hay campos de datos que están supeditados a disponer de algún componente de hardware específico, como la dinámica de ciclismo (pedales Garmin Vector), marchas (cambio Shimano Di2), indoor trainer (rodillo ANT+ FE-C), Potencia (medidor de potencia) o Varia (luces o radar varia). Esto en cuanto a páginas de datos, porque hay otra serie de pantallas que puedes activar o desactivar según desees.

  • Map, allows to show two additional data
  • Compass, allows you to display two additional data
  • Height, allows to show two additional data
  • Lap summary, which is the information you will see when completing a manual or automatic lap and where you can add up to 4 different values
  • Virtual Partner, configuring the speed of this
  • Cycling dynamics, only valid if you have Garmin Vector pedals
  • Varia, only valid if you have lights or radar Varia

These screens will be specific to each activity profile you set up, so for the indoor training profile you don't need to activate the map, compass or altitude, just like if you have a competition profile. But these pages can be useful when setting up your training profile, or creating a profile for route navigation where the most important thing will be to have a map, compass and other specific data.

In short, a multitude of options that depend exclusively on what you want to see on screen. Each activity profile also allows you to select other values, such as GPS mode. You can activate GPS+GLONASS to have the best signal quality, GPS only to save some battery power or deactivate it to depend exclusively on the speed sensor or train indoors.

Garmin Edge 520 - GPS Configuration

You can also set various alerts for time, distance, calories, HR, cadence or power, all with different values and, in the last three cases, with minimums and maximums, so you can activate an alert that warns you when your cadence falls below 70 or passes 100, or when your power exceeds 300W.

Garmin Edge 520 - Alert Settings

Finally, within the automatic functions, you can set up auto lap, auto pause, auto scroll and stop activity.

Garmin Edge 520 - Automatic Features

And I repeat again, each of these options is specific to the activity profile you are setting up and will not affect the rest. So if you want to have the same data screens in several profiles but different alerts, you will have to create different profiles, up to a maximum of 10 different ones.

General use on the bike

Well, once you've covered the general configuration of your computer, which is really the most extensive part, it's time to get out and train. The first thing you'll want to know is the speed of both startup and satellite sync. That is, the time that passes from when you press the power button until you can start pedaling. Nothing better than seeing it for yourself on a video.

It's a fairly quick process, plus at the bottom of the screen it tells you what's loading and what's left to complete the power-up. You could also add a custom message that appears during startup and delay the time until the main screen appears, I explained at the time how to do it.

In the upper left part of the screen you will see the icons of the sensors you have synchronized (pulse, power, cadence, etc) blinking. They will stop blinking as soon as the connection has been established. As you know, the sensors that are mounted on the bicycle must be activated, generally, by giving some pedals.

With GPS signal and sensors connected you can start your route now, simply press the upper right button and the activity profile selection screen will appear.

Garmin Edge 520 - Profile Selection

Select the appropriate profile and your main data screen will appear.

Garmin Edge 520 - Data Display

Now all you have to do is press the Start Activity button, located at the bottom of the device with a "play-pause" symbol. That is, we start and stop the activity from that button.

Garmin Edge 520 - Startup

The one next to it will be used to mark laps manually, if you are interested in measuring specific sections of your route (e.g. the main part of the pass climb). In case you have set in the data fields time in lap, speed in lap, distance in lap, etc. you will be able to see how much time (or distance) has passed since you pressed the button, and therefore how much you have covered, climbed, etc.

Garmin Edge 520 - Back

Of course you can also activate the turns automatically, as you'll see below. As for the data pages, you can switch between the different ones you've set up with the left scroll buttons, including the special ones you've activated, such as the compass.

Garmin Edge 520 - Compass

The altitude profile of your route.

Garmin Edge 520 - Altitude Profile

Or the map.

Garmin Edge 520 - Navigation Map

While in the activity you can access the advanced menu, where you can not only make changes in the profile configuration (alerts or data fields), but also use specific navigation and positioning options.

Garmin Edge 520 - Menu within activity

You can click on return to home to get a map from your location to the point where you started the route, in case you got lost. You can select to return by the same route or the most direct route. The first option will take you by the same roads you have used to get lost, while the second one will trace a straight line path, perfect in case you grow wings and fly away.

Garmin Edge 520 - Back to top

You can also set the height (if you are, for example, at the top of a port where the height is clearly specified) or mark a location, so you can navigate to that point later.

Garmin Edge 520 - Mark point en route

You can also enter the status screen, which you access from the main screen by pressing up, where the basic status of the device is indicated. Screen brightness, GPS and sensor status, Bluetooth or weather status.

Garmin Edge 520 - Status Display

Finally, when you have finished your route, simply press the pause button and the end of activity screen will appear. It is basically the same advanced menu screen, but some data of your workout is added at the top and the possibility to save or discard the route.

Garmin Edge 520 - Slow motion

And after saving the activity you will be able to see the summary of all your training, and in case you have broken any personal record you will be rewarded with a message on screen.

Advanced training

As a good training device, the Garmin Edge 520 has the ability to create advanced workouts by simply logging in to Garmin Connect and creating the workout you or your trainer set up for a particular day. You can do anything from simple workouts where you simply set up periods of working zones with a more demanding centre section.

Garmin Edge 520 - Advanced Training 1

As more specific sessions with different objectives, and not only to be performed outdoors, but also indoors on a roller.

Garmin Edge 520 - Advanced Training

When you perform one of these workouts, the Edge 520's display will mark each part of your workout, reminding you of your workout goal. You can create workout phases based on time, distance, calories, heart rate (to a certain number of heartbeats), power (to a certain power figure) or simply press the lap button to move to the next phase.

The objectives of each of these phases can be speed, cadence or HR zones or power (predetermined or manually created zones), so you can create a 10-minute training phase with a power between 300W and 310W, receiving a warning if you go outside one of these two ranges, either above or below.

Virtual partner

Another classic training option you'll find on the Edge 520 is the Virtual Partner. This is a familiar option, but it's not outdated, and it allows you to take on an imaginary opponent that you previously programmed for medium speed.

Buscador de chollos

Garmin Edge 520 - Virtual Partner

In addition to programming directly from the device menu, you can also have it by creating a route and selecting an average speed for that route. Once activated, it will create an additional data page where you can see the delay or advantage you have over your virtual rival, as well as the distance traveled.

Garmin Edge 520 - Virtual Partner

If at any time you want to change the speed of your opponent you only have to enter the menu and modify it. It also allows you to reset your virtual partner and bring it back up to speed, if you have taken too much distance or stopped for a beer and forgot to stop the activity.

Garmin Edge 520 - Virtual Partner

It's a very graphic way of training with respect to a goal, and not just training, as you can also use it in a race and see, at a glance, how you are doing with respect to the goal you have set before the competition.

Navigation

The Edge 520 includes a world base map, which is practically useless and its only use is to know if you have already arrived at the beach or still have some distance to go.

Garmin Edge 520 - Default Map

But now I give you the good news, and that is that you can change that map for one of your choice. However, as it does not have the possibility of expanding the memory through card (something reserved for higher models), you must accommodate the map in the space that is free after removing the base map. About 100MB.

But you don't want to have a map that size either, because you also have to leave enough space for activity files, Strava segments and routes that you record over time. The fastest and easiest way to add more complete maps is through OpenStreetMaps, maps created by the community. There are other maps, perhaps more complete or detailed, but this one I cover below is the fastest and easiest way to do it.

Step 1. Download the map

To download your map the first thing you have to do is to this page. This is the page you will see (or that you see at the time of writing, it is possible that the design will change over time).

OpenStreetMaps

The most important part is to select in the first option the type of map you want to download, in this case "Routable Bicycle". Once you have selected what type of map you need, the next thing is to zoom in and select the areas you are going to move through. Your thing would be to select the whole country and forget about it, but I remind you that the storage space is limited, so you better select the part where you are going to do your routes. To do this, first zoom in on the area in question and then activate the option "Enable manual tile selection".

OpenStreetMaps

Now click on each box that interests you. In my case, the area that covers the coast of Malaga, so I select those boxes. All you have to do is enter your email address and press the "Build my map" button.

OpenStreetMaps

You will receive two emails. The first one will indicate that your request is queued, it is an automatic notification. Secondly and depending on the workload of the OpenStreetMaps server (I usually get it immediately after the first one) you will receive the email with the download link.

OpenStreetMaps

And by clicking on the link you will access the download page of your map. The file you are interested in is the one I have pointed out.

OpenStreetMaps

Download the file, unzip it and put it in an accessible place (for example on the desktop), because we are going to use it next.

Step 2. Install the map

You now have your map downloaded, unzipped and on your desktop. The first thing you need to do is rename "gmapsupp.img" to "gmapbmap.img", as this is the file Edge 520 will search for in memory. If you don't see the file extension don't worry, just rename the file. Then connect the device to your computer with the USB cable and access the Garmin folder, where you will find the original gmapbmap.img.

OpenStreetMaps

You must delete the original file, although it's best to make a copy and save it first (you never know what it might be needed for). After deleting it, if you're on a Mac, you must empty the recycle bin before disconnecting Edge 520 so that space is effectively freed (a very important step). This is not necessary in Windows. Copy the file you downloaded to the device and you're done.

To summarize, and to put the guide in a clear way, these are the steps you must follow

  1. Download the map you need from garmin.openstreetmap.nl
  2. Unzip the file and rename it to gmapbmap.img
  3. Connect Edge 520 to your computer
  4. In the Garmin folder, find the file gmapbmap.img and save a backup, then delete it (and if you're using a Mac, empty the recycle bin)
  5. Copy the file you downloaded and renamed to the same location
  6. Disconnect the Edge 520 from the computer and go out and pedal.

As you can see, the difference in the information present on the map is quite remarkable.

Garmin Edge 520 - Full Map

Well, one thing you should be clear about is that despite having maps, there is no point-to-point navigation, as there is with a car GPS, so you can't just stand in the middle of nowhere and ask Edge 520 to take you home and calculate the fastest route to get there, indicating the intersection on each street or road to get there.

Instead, we have point-to-point routes, so there is a point at each intersection that tells you when to turn (but does not specify whether it is A Street or B Street). And of course, you must create this route before you can leave in Garmin Connect. The map is a "logistical aid" that you can use for reference. For more advanced navigation options, look at Edge 810 or Edge 1000 (or Edge Explore 1000).

And if you are going to navigate in another location tomorrow, the procedure is the same. Replace the map you just installed with the new one you downloaded and that's it.

Strava

Without a doubt, the most important new feature of the Garmin Edge 520 has been the arrival of live Strava segments on the cycling computer. Until now, Garmin segments have been available on many of its devices, but they are not as closely tracked as Strava segments can be.

The fact is that in this sports social network, the bites are the order of the day. That KOM that was taken away from you a week ago and that you had so much trouble getting. Being the first of your friends in a certain segment. Or simply, beating your previous record in a certain segment, like the climb to the top of your town.

This new option allows you to compete against Strava segments that you have previously marked as favorites, for which you have a set goal, or simply that Strava thinks might be of interest to you. However, in order for the data to be constantly updated you must have a current Strava Premium subscription. When you purchase the Edge 520 you are entitled to 3 months of use at no cost.

Strava segments from A to Z

The first thing you need to know is how to get the Strava segments to your device. There are three ways for those segments to appear

  • The most direct, mark them directly as favorites (the star you can find in a certain segment)
  • Those segments where you've set a goal
  • Finally, segments that Strava can randomly select in your area and that you may find to be of interest

The first two cases are pretty obvious. For the third case, Strava's magic has to work; although in my case that magic has been a bit muted, as he has selected some segments that I doubt very much that I will visit. Yes, they are relatively close, but not on routes that are of interest to me.

These selected segments will be updated each time you connect your device via USB or each time you perform a Bluetooth synchronization with your mobile phone. In addition to receiving the relevant information for that particular segment (data such as distances, location, elevation, etc.), you will also get the updated list of times at that precise moment.

If a friend of yours updates their time from the time you last synced until you complete the segment, you will still be shown the previous time, as the data update is not constant.

Garmin Edge 520 - Strava Beats

Garmin Edge 520 - Strava Segments

When you're training, you'll be alerted when you're about to approach a segment you've marked as being of interest, and it will mark the distance you have left to go so you can prepare to beat that time (obviously, gain speed before starting the segment).

At the top you will see information on the target time (which can be the leader of your contact list, your personal record or the absolute record for the segment), while at the bottom the remaining distance to the starting point will be deducted.

Garmin Edge 520 - Strava segment startup notice

You can select this goal by entering the options through the menu button, either before starting the segment or while you are doing it.

Garmin Edge 520 - Strava change target

You can also check what the target time and average speed is for each of these targets.

Garmin Edge 520 - Strava Lenses

As soon as you reach the start of the segment, the display will appear so you can start giving it your all.

Garmin Edge 520 - Strava start segment

As you progress through the segment, the information will be updated to tell you how much distance is left and how you are doing in relation to your target, behind or ahead, and in how much time.

Garmin Edge 520 - Location in Strava segment

There is also the possibility of not following the route with the map, and simply changing the data screen to another Virtual Partner screen, probably more representative of how you are doing with your objective.

Garmin Edge 520 - Strava Virtual Partner

When you reach the end of the segment it will tell you your final time as well as whether you have set a particular record or, as in the case below, it has been quite poor.

Garmin Edge 520 - Strava End Time

Segment completed and results obtained. Now you can go for another one or, if you think you can improve it, turn around and try again. These results are not available on Strava at the precise moment you complete the segment. They will be as soon as you finish your current training and synchronize your activity

Indoor ANT+FE-C training

Another new feature of the Garmin Edge 520 is support for the ANT+ FE-C standard. And what is this? The FE-C (Fitness Equipment Control) profile allows different devices to control the resistance of intelligent rollers that obviously also have to support this function. This allows you to use applications such as ZwiftThe BKool simulatorThe Trainer Road advanced trainingsetc.

That is, the application controls the resistance of the roller to simulate climbs or descents, or to set training goals per watt. The Edge 520 also allows you to connect to these types of intelligent rollers and have our computer control them in various ways, for example, in one of these ways:

  • Set a few watts as a target, for example 275w. The Edge 520 will tell the roller that this is our target and will maintain the necessary resistance to work that intensity.
  • Follow a workout created in Garmin Connect. You can access the Connect workout section and design a workout or schedule one as directed by your trainer. After doing so, the Edge 520 will send the appropriate resistance information to the roller for each phase of the workout.
  • Repeat an activity that you have already done, for example the last outing that you have done outside. It will reproduce the tilt points in the same way that you have done it before.
  • Route tracking: it allows you to create a route on the map and reproduce the inclinations present on the route, so you can follow the route of a race, such as the queen stage of the Tour de France.

Garmin Edge 520 - ANT+ Roller

These are really interesting options, especially when it comes to the route of a race you are going to do, so you can see beforehand the effort needed for each point of the race and thus establish a pattern of rhythms to follow.

History, statistics and records

The unit allows you to access your entire workout history directly on the device's screen, if you do not currently have access to your computer or phone for Garmin Connect data.

Garmin Edge 520 - History

You can review the activity data again.

And on each of these laps, you can see the specific details of the marked lap.

The time in each heart rate zone

Garmin Edge 520 - Zone Weather

It also offers you the possibility of creating a route from that activity, in case you want to travel it another day. Not only is there information on each of the activities in detail, but it will also offer you total data on all your activities, as well as breaking down the distances covered in each of the profiles you have created.

Garmin Edge 520 - Total Summary by Activity

Garmin Edge 520 - Total Summary by Activity

Among your personal statistics you can find values for your maximum VO2 in cycling and your FTP. For both values you need a power meter. The VO2 is the maximum volume of oxygen you can consume per minute per kilogram of body mass. That is, the higher this value is, the greater your athletic ability. The theory is that this value will increase as your physical condition improves, so it allows you to track how you are improving.

Of course, if you are just starting out in sport this figure will increase rapidly in a matter of months, but when you have been playing sport for years it is much more difficult to see variations in this figure. I usually move between 57 and 58, but I don't usually get out of these values. At first it is possible that they will vary significantly, as the algorithm needs a few training sessions to get to know you better as an athlete, so you should give a time frame of about 5-7 starts for this figure to stabilize. Remember, this is a mere approximation, it can never replace a real stress test where your VO2max will be measured accurately with a spirometer.

The FTP (Functional Threshold Power) is an increasingly important value in cycling. It is the power figure that a cyclist can maintain in one hour of effort (or during 40km). Its importance lies in the fact that it establishes a power threshold. If we make a continuous effort above this figure we will end up running out of power. Very important in triathlon events (where you have to run after the bike) or in long cycling events where you can still be hours ahead.

Finally, the Edge 520 keeps track of your personal records, such as furthest distance, fastest 40K, maximum power maintained for 20 minutes or maximum climb

Garmin Edge 520 - Personal Record

Garmin Edge 520 - Personal Record

These records are not only indicated in the statistics menu, but also appear on the screen at the end of the activity if you exceed any of them. The records are device specific, so if you have better records stored in Garmin Connect you should go to the corresponding section and indicate that you want to synchronize those values with your new Edge 520.

Compatibility with Varia and Varia Radar lights

After the firmware upgrade to version 3.0 the Garmin Edge 520 was supported to connect to the Garmin Varia lights and the Varia Radar rear vehicle detection system.

Garmin Edge 520 - Vario Radar Connection

The way to connect to these devices is somewhat different from a traditional sensor. The radar and lighting devices do not connect directly and separately to the Garmin Edge, but first form a network with each other. This allows the Edge to use a single ANT+ channel (since they are limited) to communicate with all the lights, instead of having to use one for each light.

The only thing you'll notice that the connection is something special is that you'll now find a menu in the Edge 520 where you can see which lights you've connected and you can change some of the settings for their operation.

With the radar already paired, you'll receive on-screen alerts of approaching vehicles, both by the colors that will illuminate the edges of the screen and by a line on the right side, where there will be a dot for each vehicle driving behind you.

But this one I'll talk about later in the specific radar test.

Battery life

This is the second time this has happened to me, and in both cases with cycling units. The first was the Garmin Edge 25And now with this 520. The fact is that from the officially announced autonomy figures to the real figure is far from it. But in a positive sense (much more battery life than was supposed).

For the Edge 520, Garmin indicates that the battery life is "up to 15 hours". Well, after I put the Edge 520 through my usual battery life test (charging the device, starting an activity, and waiting for the battery to run out), this is the result.

Garmin Edge 520 - Standalone

Over 21 hours of total life, even with the GPS + GLONASS option activated (which increases battery consumption). It's true that the test was performed without ANT+ sensors or a connected phone (but Bluetooth was activated), but it certainly doesn't have such a high impact on battery life. It's certainly an outstanding result, but I find it hard to understand why Garmin only announces a maximum of 15 hours of autonomy when it goes well beyond that duration.

Internal and external sensors

When talking about sensors, we have to differentiate between the sensors integrated in the device itself and the external sensors. The first ones are the ones the Edge 520 has inside, and the second ones are the sensors the device can be connected to. The Garmin Edge 520 obviously has GPS. What we have to point out is that it is equipped with GLONASS, so it can also receive information from the Russian satellite network. This increases the location accuracy and speed when establishing the initial position, at the cost of a little more battery consumption, around 15%.

No less important is the barometric altimeter, which you can use to know the elevation. But not as an absolute value, since it depends on the atmospheric pressure. What it will allow is to count the meters of ascent and descent in a quite precise way. By default the altimeter will be automatically calibrated when you start an activity, through the GPS data.

If you want to have accurate altitude data throughout your route, you can get it by making a manual calibration at some point where the altitude is specified with total accuracy (for example, the highest part of a mountain pass). This can be done from the menu within an activity.

Garmin Edge 520 - Configuring Height

The compass we can find is not magnetic, but it is through GPS, so while we are moving the direction indication will be accurate (because we are moving in one direction), but if we stop it will not be able to determine where we are looking.

This can present a problem if you are navigating a route and try to decide which of the two paths to choose, because the map will start to turn on itself as it cannot identify your orientation. This magnetic compass is present in clocks, but not in cycling computers, and it is certainly not something you will miss (especially for more complicated routes such as those made by mountain).

Garmin Edge 25 - Compass

Finally, another sensor integrated into the device is the thermometer. Like the compass, there are also watches where it is possible to find this temperature sensor, but here it makes sense. While the sensor in the watch is affected by our body temperature, in the Edge 520, when mounted on the handlebars, it will provide a correct temperature.

The temperature will be displayed on the main screen, at the top next to the time, or during the activity by entering the menu options (by pressing the top right button) so that the top status bar appears. You can also add a temperature data field, however.

Garmin Edge 520 - Menu within activity

As I say, those are the sensors built into the device. But thanks to the ANT+ connectivity we can connect to a lot of external sensors:

  • Pulse sensor
  • Speed and/or cadence sensor
  • Power meters
  • ANT+ lights (like Garmin Varia or Bontrager ANT+ lights)
  • Garmin Varia Approach Radar
  • ANT+ rollers, receiving power and speed data
  • ANT+ FE-C rollers, controlling their resistance (and of course receiving information from them, if they support it)
  • Garmin VIRB cameras
  • ANT+ scale

When you connect to these sensors, not only will you see the information they provide on the device screen, but it will also be saved in the FIT file of the activity, so when you finish and synchronise, you can review all the data in Garmin Connect.

Garmin Edge 520 - Sensor Information

 

Connectivity

With the Edge 520 you can connect to two types of devices wirelessly, thanks to ANT+ and Bluetooth Smart. In the case of ANT+ you can connect to external sensors or training rollers as discussed above. That is, it is capable of connecting to all the sensors you would expect from a high-end cycling device, with the inclusion of the new ANT+ FE-C profile that debuts with the 520. Like the Garmin Edge 1000, the Edge 520 also has Bluetooth connectivity to pair with your mobile phone. This pairing gives you different features.

First of all, and being already a classic in the Edge series, we find the LiveTrack. It allows you to transmit your position in real time, and it does it together with data of speed, pulses, cadence, etc. The tracking can be done through the Garmin website. To start the session you will have to do it through the phone application, and of course you will have to take it with you while you train, since it is the one that sends the data to the server.

Anyone you give the link to the application will be able to follow your training. It's a very useful way to keep your family calm, knowing that nothing serious has happened to you, even though it's a double-edged sword. Now they'll know that the reason for going out with your bike is not to go training, but to go out for a beer.

Garmin Livetrack

On the Edge 520's screen you'll also receive notifications from your mobile phone, but the service isn't as extensive as it is with watches. On the cycling computers we'll only receive call alerts (both ongoing and missed calls) and SMS messages, so you won't receive alerts for social networking messages, e-mail or WhatsApp. And it makes a lot of sense, because the idea is to keep an eye on the road and not the latest joke in group chat.

garmin-edge-520-notification-call

One of the options offered by Garmin Connect is to update the weather data for your area. And when I say area, it is a very large area. For example, in my case the weather provided is for Gibraltar, as it must be the closest weather station to my actual location (Marbella).

Garmin Edge 520 - Gibraltar Weather

By scrolling down we can access the forecast for the next few hours.

Garmin Edge 520 - Hourly Weather Forecast

Alerts are offered along with the weather information, something that only works in some cases and I suppose it will depend specifically on whether the weather station you are getting data from sends out these kinds of alerts.

Finally, thanks to the Bluetooth connection, we will also automatically synchronize activities as soon as you complete them, so you don't have to connect the Edge 520 to your computer to transmit the data. This synchronization is bi-directional, so when the Edge 520 connects to your phone you will also receive updates on satellite cache data, time changes on Strava segments, workouts or routes created.

Garmin Edge 520 - Mobile Synchronization

This time, Garmin has not included WiFi connectivity in the Edge 520, something that the Edge 1000 has. has already announced is the arrival of the platform Connect IQ to the Edge devices, which will allow you to install applications and data fields not only on the clocks, but from the first quarter of 2016 on any of your cycling computers, starting with this Edge 520.

My opinion

Garmin Edge 520

As a training unit, the Garmin Edge 520 delivers on its promise, and it does so on a very good note. This device has absolutely everything you could possibly want in a cycling computer you'll be using for training, and more. Despite its small size, it comes loaded with all the training options already seen in the rest of the range, and there are exclusive new features such as the ANT+ FE-C roller control.

There will be some features that some of you may miss, such as the absence of a touch screen, not being able to insert a memory card to install larger maps or navigation being too simple. The absence of WiFi is also noteworthy, not for its usefulness itself but simply because it is something we are seeing as usual. But it is clear that something must be left for future models of higher ranges (for example, when it is presented substitute for the Edge 810).

Personally, the only problem I can see is that sometimes it is a bit clumsy in terms of processor. Going from one page of data to the map, and then to another page of data makes it freeze for a moment. The problem is that there is no indication on screen that it is working, so it feels like hanging up, and you press the button again in case you haven't pressed it properly the previous time. But more than a defect of the device, it is a deformation of the fact of using tremendously powerful phones (and with much less autonomy), and we want everything to work just as fast.

If you're looking for a training partner, the Garmin Edge 520 is one you can get right down to business. The only people I won't recommend the Edge 520 to are those who do a lot of sailing, because that's the only place this Edge is loose.

Did you like the test?

I hope this test will help you decide on your next purchase. As you know, each of the analyses you can read on the web requires many hours of effort. If you like the work I do and want to lend a hand and support the site you can buy the Edge (or any other item) through the links belowYou get a very good price and they return a small commission which is a great help. All without any cost to you.

As you know, if you have any doubt or you think I should have commented something else, you can leave a comment and I will answer you as soon as possible. Share this test with your friends, don't be selfish, I'm sure they like it too. You can do it through social networks or, as we have done all our lives, by word of mouth.

Buy Garmin Edge 520

There are two versions available for the Garmin Edge 520. On the one hand the standard, cheaper version, which is the one I tested. But there is also a pack version, which includes the pulse, speed and cadence sensors. If you don't have any of them, it's a very good opportunity to get them. Below I provide you with links to good offers.

  1. Hi, I'm Joaquin. First of all, thank you very much for the very complete and detailed analysis. I would like to ask you just one question. You mentioned that it has up to five different screens. Now, is it easy to go from one screen to another?

    1. Hello Joaquin

      Yes, simply press the up or down scroll button to switch between them, or turn on the automatic scrolling option to toggle the display.

      But if you have to go through some heavy screen, like the map, it slows down a bit.

  2. Hi I'm Jose Antonio. Thanks for your help and my question is if the 520 can connect with bluetooth sensors for speed, cadence, pulse?

      1. Hi Eduardo, I understand you can connect via Bluetooth with the Specialized Turbo Levo and its Mission Control application.

  3. Hi Eduardo, I'm thinking of buying a Garmin edge 520 or 810 and I'd like your opinion.
    I did mountain and road biking at a cyclotourist level but with a personal trainer and my doubt is to buy a Garmin and then have software problems or not have good connectivity, etc.
    Which one do you advise?

    1. If you want it to train mainly, although with navigation possibilities, no doubt the Edge 520, and more with the price it has now at Amazon.

      If you put more emphasis on navigation, then the 810 is a better choice.

  4. Hello, my name is Vicente, thanks for the test, is fantastic and has removed me from doubt, just one question, you know if the Bluetooth connection with an IPhone makes it correctly ..., the IPhone with Bluetooth are a little damn, thanks and a greeting.

    1. Hello Vicente

      Yes, it works well, both for performing constant data synchronization and for displaying call and SMS notifications.

  5. Hello,

    Very good analysis. Just one question, the speed and cadence sensors of the 520 are identical to those of the 810?

    Thank you for your attention,

    Fernando.

    1. The three months of Strava are activated from the Garmin Connect segments tab, which will indicate if you want to change the Garmin segments to Strava segments and allow you to activate the free months.

      1. Hi, Eduardo,
        Great test and thanks for your time.
        I would like to know if in the 520 you can download routes directly from wikiloc or other platforms?
        If these routes are outside the maps I have downloaded on the 520 in order to follow them I would have to download the map of the area?
        Greetings.
        Alfonso.

        1. Thank you, Alfonso.

          Yes, on Edge 520 you can install paths directly from Wikiloc's Garmin functionality.

          The routes are simply a track to follow from point to point, regardless of the maps. If there are maps, the route will be shown on them, if there are not, the route will simply be shown.

          1. Hi, I'm new at this and I really don't know how to use a downloaded track. For example, I downloaded the track for a test, but I don't know how to follow it....

          2. If you have downloaded a GPX file, you must enter it into the memory, in the NewFiles folder. After disconnecting and restarting the device, you can find it among the destination options for route tracking.

          3. Hello, again I consult you. I installed the map as you indicated perfectly in your post, but I can't get the maps to appear once I'm on the road... something I'm doing wrong and it escapes me... I see my way... but no maps. What can that be?

            Thank you for your time.

          4. Then there is something that is not done correctly, because there is nothing to activate on the device. The map must be loaded every time you start Edge 520.

  6. Good morning,

    Thank you for the information provided. One question, in this one there is the option to put the bikes you have to relate the activity to the bike you do?
    Thank you very much in advance and best regards.

    1. No, in the case of the 520 there is no separation of bikes. What there is is a set of sensors independent of the demarcation of a bike. That is, you can synchronize it with the sensors of more than one bike without having to make the pairing each time you change bikes, but you cannot set several bikes according to the profile.

  7. Good afternoon, you are doing a great favor to us newcomers in this GPS with your analysis and advice, following them I have found that my garmin does not have the file gmapbmap.img, but a gmapbmap, about 50 megs, which I guess will be the same, and if so, I have to add to the map I downloaded .img or not necessary? Another question is whether to use it in mountain biking to mark the tab routable bycicle or not. Thanks for your help and continue with this interesting blog. Greetings

    1. Yeah, the same file you have in memory, you name it the same way.

      For mtb I haven't tried it, but I guess you have to check the same options.

      1. Thanks, I already tried it, the maps only indicate roads, even cattle routes, but if you go through the mountain they are blank. I'll put the Spanish mole in and fix it, now that you've shown me how. A greeting

        1. Hello Juanma/Eduardo,
          Can you explain me how to do it with the Topohsipania map? I can't do it with this map and it's the most complete one for MTB.

          Greetings and thank you

          1. You'd have to install it in Garmin BaseCamp and then move it to the device. I'm sorry I can't give you more details.

  8. First of all, congratulations on the great work you are doing, my question is as follows,
    I have the potentiometer in the left crank, the stage, and when it reads the watts I think it doesn't calculate the average, and it finishes reading and indicates me error +1
    You know how I can fix it?
    Greetings

    1. You mean when you're calibrating? Or during use?

      The first version of the Stages had a problem with the battery cover, which caused problems with sudden disconnections. That could be the problem. I recommend that you contact the manufacturer, because it is being replaced under warranty.

  9. Hello, is it possible to enter tracks (wikiloc, ...) for MTB routes in the Garmin Edge 520? and if so, how?
    Greetings.

  10. Congratulations for your analysis, after using it I have a doubt if you take me out of doubt, the altitude screen, you can not zoom in on the profile ... as in the 810, you could put more altitude and distance to see the full profile, because I get small values and is not whole, I do not know if I have understood what I mean
    Greetings

  11. Hello, first of all I want to congratulate you on the article, I'm thinking of buying the 520 and has solved many doubts, but I still have one if you can clarify it. The idea is to use it with 2 bikes, a mtb and another road and I would like to know if the total mileage meter is the ODO, is one independent for each bike or is unique and add all together?

    1. No, it's all-inclusive, since you can't set up different bike profiles.

      But in Garmin Connect you can set up two different bikes (on your computer) and you can select which one you have used for each ride, so you can see the mileage for each one on the web.

  12. Hi Eduardo, I want to congratulate you for the complete analysis and the clear instructions. I've been suffering for a week with the user's manual and trying to guess things that I finally managed to solve thanks to your help. I would have loved to read this review before buying my Edge 520, because the salesman at Garmin store told me that between the Edge 520 and the Edge 1000 there was only a difference "the touch screen and that in the 1000 everything looks nicer because it is in color". For me the subject of navigation is very important, especially because I want to explore mountain paths with the MTB and I already realize that maybe it wasn't the best option. However, by reading everything you've written and seeing all the advantages that this gadget does have, then I will try to find the positive side and get the best I can for my workouts. I don't have much choice because the purchase is done and I suppose that it won't be so bad either. Receive a greeting and my thanks

  13. I'm discovering your website and there's a lot of information that I was looking for a long time ago! Until now I used my mobile phone on the bike, but I'll look to try the Garmin East.

  14. Hey, Eduardo, congratulations on the analysis of the Edge 520. Tell you I already bought it and it's fantastic.
    Everything as you explain it on your page has been perfect, except for one thing:
    I can't get Bluetooth to link to my phone. I've followed the steps and they're all fine. On my phone, a BQ 5, where it says "paired devices" I get the Edge 520 to accept, but it doesn't refer to anything else. The only thing is that the Edge 520 lights up with a green and white figure that says Waiting for Bluetooth.
    But that's as far as I go.
    Waiting for your precious answer.
    Thank you very much.

    1. Hi Xavi

      I can't help you with reference to your particular case with BQ. I know that brand is having some problems with other watches (Polar, for example), so I don't know if it can be a problem concerning their software.

  15. Hi, I'm interested in this cyclocomputer, but before buying it I'd like to know if it's like its little brother, the Edge 500, which, when it was in the middle of a route and wanted to recharge the battery, the route would close and a new route would have to be started.
    Unfortunately for some of my routes a 15 hour range is not enough and I need to recharge the battery during the route without it restarting.

    1. That's never happened to me, but nowadays when the battery runs out when you turn it back on, the activity that was going on is paused and can be continued, so it should be the same for the Edge 520.

  16. Hi, I'm an Edge 520 user and I just had a question, I have a saved route through wikiloc, it's a race that consists of 2 laps but they have only uploaded the route of one lap (of course), the doubts I have are: the day of the race when I finish the first lap that will indicate the Garmin? I will have to hit the button to start again (with the consequent loss of time)?
    I don't know if I've made myself clear...jj
    Well, I hope you can help me... tell you that the analysis of the Garmin 520 has been very helpful, it's one of the best I've been able to read... congratulations.

    1. It will tell you that you have completed the route. It will continue to record, but they are route. You can either restart it or create it as a double in Connect, but do it by hand.

  17. Hello and congratulations on your blog.

    I have an ANT+FE-C compatible roller and I currently have a Fenix 3 and an eTrex 30 that are not compatible with them.

    I have seen the 520 test and I am almost decided by it. I have a question, do you have any fit file obtained from a roller training, could you leave it for me to study it and the other question, when you train with roller against a previous path or activity, the generated fit file shows the map or is it empty as an indoor activity?

    Thank you

    1. I'm not very fond of training indoors, mainly because living where I do is not necessary (I can go out any winter night to train without much trouble), so I don't have any FIT file.

      The FIT file generated in a workout does not include maps of any kind, since even if it is based on a past activity, the device records the current activity (and it is recorded as an indoor activity). That is, the file will contain all the data on pulse, power, etc., but without coordinates or anything else.

      1. In my case I have no choice but to train with a roller during the week because of the work schedule.

        Thanks, the fit era to see how often you save data indoors, sometimes these terminals make very big peaks of time.

        And the map thing, perfect, I didn't want it to come out with a map to avoid putting in Garmin Connect that it's an indoor activity or anything to differentiate it from the street outlets... for example Bkool puts the map in when I repeat an activity and it's something I don't want or need.

        At the moment to avoid that I'm using myetraining from Elite, export to TCX and then garmin connect... waste of time, problems when putting the files, etc. etc. that's why I decided to go for the 520.

        A salute.

  18. Eduardo, great test, as always. One question to see if you know anything. When will the ConnectIQ apps that look so good on this Edge range be available? Congratulations on your blog.

    1. The applications are ready (at least for the developers), and all that remains is for the corresponding updates to be released for the devices. Garmin has set the first quarter in principle, so it should not take long.

  19. I congratulate you on your very interesting article.
    I would like to know if every time I put a lap and it is saved it starts again from zero to count. I say this because I am interested in doing series and I want the counter to be reset without having to end up restarting everything

  20. Hi, I'm Manolo and I'm the owner of this bug, I just have a question, I only get the profile of the activity when I finish it, but I don't get it DURING the activity, it seems that the zoom is too close, I don't know if it will be like that or on the contrary I'm doing something wrong, thanks and a greeting.

  21. Hi I have the 810 and I'm looking to change it to the 520, do you think it's worth it?
    Does the 520 have the glonass for the accuracy of the altitude and the percentages of difference in level?
    Thank you very much.

    1. Well, unless you have a roller with ANT+ FE-C technology, you're not going to have any other benefits. I don't think it's worth it. For the altitude calculation what is used is the barometric altimeter, there GLONASS has no influence.

      1. Thanks a lot, I'm going to keep the 810. Greetings and congratulations for your comments. Sent from Huawei mobile Subject: Eduardo has replied to Gabriel in "Garmin Edge 520, cycling computer with GPS | Full analysis".

  22. Hello, I have been looking and can not find the option to see the time of my location, and I see that you in Gibraltar if it comes out, where is that option. I have already activated it in garmin connect but in the 520 I do not know where I can see it. Thanks in advance

  23. Hello!
    I just bought this 520 model from Garmin and I'm still studying the manual. I loved it but I missed an absolute odometer. This is that it counts all the kilometers of the bike and also that it can adjust to a colo value occurs with the most basic cyclo computers.
    Thank you and a greeting
    Mgrau

  24. Hello, congratulations on these analyses, but useful k the instructions themselves. I would like to know if it works for stage routes, that it records the whole track and stages separately, thanks

    1. It could be done by pausing and then resuming, but personally I think it doesn't make sense. It would be better to do one activity for each day and separate the data from each one.

  25. Hey, great article.

    I'm considering buying this model. I come from a Dakota 20.
    A detail to which I give a lot of importance is the altimetry profile of a track previously loaded in the gps.
    Does it mark your position? So you can see what you have left x up...or down...or flat. Or is the profile just a "picture" that doesn't indicate anything except that...the profile.

    Thank you.

  26. Hello, I'm Alberto. Thank you very much for the analysis, which is very elaborated and very useful. I wanted to ask you a question, I'm thinking of buying the 520 or the 1000, my doubts are related to the maps. Normally I'm on the road, but when I'm in the mountains or soon on the road to Santiago I'd like to be guided with downloaded maps and to be guided with them in my different routes. As you see one and another? I've already read comments, but it seems to me that the 520 might be a little poor, no? Thank you in advance for your answer.

    1. If you're going to be sailing frequently, the Edge 1000 is a much better choice.
      Besides the screen size (and the fact that it's touch-screen), what differentiates both devices is the route tracking, which is much better in the case of the Edge 1000.

  27. Morning.

    First of all, congratulations on the article, which is very, very complete.

    I'm having trouble turning segments over to the 520. From Strava I understand that it doesn't work if you're not a Premiun, but from Garmin Connect it doesn't work either. In Garmin I mark them as favorites but it doesn't pass them. Can you help me?

    Thank you very much.

    1. Thank you, Luis.

      If you have activated the Strava segments, what has happened is that you have deactivated Garmin's. You cannot have both options simultaneously, or one or the other.

      Garmin's segments are "worked" through by creating route navigation routes. You must activate the cycling segments option and save the route. And don't forget to activate the segments option on the Edge 520.

  28. Hi, thanks for the info, I have a problem and the data of the percentage of the maximum of my rmc does not come out, it comes out two lines, why is that?

    1. No, I don't have a printable version, but you can do it from the browser.
      Be sure to load all images by scrolling to the bottom of the test (up to the comments)

  29. Hello!
    I found an incredible analysis by far the best I've seen of all, I'm doubting between the Polar V650 or the garmin 520, which would advise me to follow track, what differences between both, the polar is substantially cheaper 100 euritos, it's worth the difference.

    Greetings and thanks

    1. At the moment, the official Polar route navigation is very limited. You can't make new routes, only those you have already made or that other users of Polar Flow have made, but it is not possible to upload a new one or create something from a map. There are tricks ( https://www.correrunamaraton.com/importar_rutas_polar/), but if the main purpose is to navigate with the device it doesn't seem to me to be the best option.

      If 520 navigation works for you (track tracking, not point-to-point navigation), it's perfect. If you need navigation with directions (like a car navigation system) you should choose Edge 810 or Edge 1000.

  30. Congratulations for the article, I found it very complete and of great help for those of us who are starting out in this world.

    The only point I think you left out is how to connect it to an electronic gearbox, for example the Shimano Di2. I read that you have to buy the following device "Shimano Wireless Unit - SM-EWW01 for E-tube Di2" (I don't know if this is the latest version) and a cable (Shimano Di2 E-Tube single cable) which is not included in the device and is necessary for installation.
    My question is, do you know how long this cable has to be for a size 54 bike? I've seen it in the following sizes 150, 200 and 250mm.

    Thank you very much and congratulations again!

    1. Thank you, Carlos.

      With the Di2 I can't offer you much help, since I don't use electronic gear, but I can confirm that you do indeed need that SM-EWW01 that will send the signal to the Edge. As for the length of the cable, more than the size of the frame depends on the design of the rear pods. Here's the manual where you can see how to connect it. In most cases I suppose that with the 150mm cable it will be more than enough.

      1. Thank you very much for the quick answer Eduardo. I'll take a look at the manual you passed me. And do you know if the "SM-EWW01" is the latest model from Shimano?

  31. Hi, Eduardo,
    Congratulations on the test, but you can't ask for more.
    I'm one of those between 520 and 810. I'm on the road and in the mountains, and I want something that can do both.
    I come from a 500 and for road I had everything I could need, I don't train doing series nor do I need something very sophisticated in terms of training, nor do I follow tracks with the skinny one.
    What I wanted was something better for MTB, we went out with a large group with the track loaded in the GPS to follow the route. I am interested in the navigation, apart from tracking the track, the detours to trails, junctions, etc, that the altimeter screen can be changed to see more or less area than the one that limited you in the 500.
    After reading all your answers I have a question: Apart from the memory capacity to load maps, something that is secondary since I think that the 520 fits all the community where I live, what differences are there in terms of navigation with the 810?.
    I thought the navigation system on the map was the same for both.
    Thank you.
    A salute.

    1. The Edge 520 has a point tracker, which is a list of breadcrumb-like points. Edge 810's navigation is more complete, car-style, and is able to tell you if you miss a turnoff on which road to take next.

      1. Thank you very much, Eduardo.
        Once the doubts are cleared up, I know that the model that best suits my needs is the Edge 810. I have also seen that the altimetry screen can be zoomed and adjusted to your liking.
        A salute.

      2. Hi Eduardo, sorry to bother you once again, but a last minute doubt has arisen regarding navigation, it seems that I am not totally clear on this subject.
        You have already clarified to me that the 520 does not have navigation itself, that you cannot tell it to take you to a particular point for it to calculate the route, but to follow a track along mountain tracks and trails, which you have previously loaded into the device, where there are no streets or avenues, etc, you would get the same performance on both devices?
        I would like to understand what advantages I would get between one device and another in this particular aspect, is what I do the 95% of my exits, follow a track previously loaded. Apart from the road exits where I practically do not use the GPS, for example, if you leave the path indicates if you are deviated so many meters in one direction, if you mark the detours at the entrance of a path, etc.. What things if I would do the 810 and not the 520 and vice versa. What do you think would be best suited to my needs?

        Sorry about that, I don't want to mess up and even more when some store told me that the 810 is no longer manufactured and in Garmin USA, although they still sell it because they have stock, in the presentation of the devices I think it no longer appears.
        Thanks in advance.

        A salute.

          1. Okay, Eduardo, thank you very much.
            The concept of routable/non-routable has already become clear to me and that it is what best suits my needs.

            A salute.
            Paul.

  32. Wow, brutal article, I found it by chance and now I feel like buying an edge 520, my mother...

    There is something that is not very clear to me and that I have searched both on the internet and on youtube. I would like to upload a track of some training of mine or of wikiloc. And I would like that to be my Virtual Partner to see if I am improving or not. That is possible right?

    On the other hand, also by uploading a track to the device, can you track it in real time through the profile screen or altimetries? That is, to know how many ports I have left to upload etc... Could you also use this altimetries screen to use the Virtual Partner?

    Many doubts I know, but that's what I want this thing for... If someone could give me a hand I would be very grateful!

    1. Yes, the virtual partner can be configured at the speed or time you choose to try to beat him in successive trainings.

      You can have an altimetry screen, but you can't not zoom in and out. If I remember correctly, the next 400m will come out, but you can't see what's ahead on the route.

      1. Thanks Eduardo!!! I would not be interested in setting up the Virtual Partner with a time or a speed, but to the results I did a week ago for example... That is, at km10 I was 2min ahead a week ago. I understand that but before buying blind...
        Okay with the altimetry, thanks!

  33. Hi, Eduardo;
    A great job, and I assure you that I have looked for info in several sites and languages. I think the main thing is that the tests are real and of course the experience is a degree.
    I am determined to make the step from Polar CS500 and RCX3 with GPS, to Garming in principle a FENIX3 and I wanted to complete it with something more specific for the bikes, possibly a 520.
    *) Do you see that combination as appropriate?
    *) I understand that both Fenix 3 and 520 can be connected to a single sensor (speed, HR band...) at the same time... so I can make the handlebar of the bike look like an airplane's 😉
    *) On the other hand I think that only one will be the one to dump the data, and it will have to be the Fenix 3 since it will be the only one that can give me service running and cycling... with this I miss some info?

    Thank you!

    1. Yes, the combination works perfectly (in fact it's what I usually use when I'm not trying anything else).

      As you say, ANT+ allows you to connect a sensor to several devices, so it can be connected simultaneously to Fenix 3 and Edge 520. You won't lose any information.

  34. Hello, I have selected the areas I wanted to download, the maps have sent me the selected part, but I do not have any files to decompress. I have been blocked in this step, I only have five folders and none with files to decompress. Thank you very much, very good analysis

    1. Check the procedure and that you have checked the same options that you see in the images, because I just performed it and it works as specified in the instructions.

  35. Hello, I would like to know if you can put the distance on the altitude screen and see more travel.

  36. Hi Eduardo, congratulations for this fantastic article, I want to put tracks in the edge 520, without creating an activity, to be able to follow the route in my exits. I use a web called cronoescalada that gives direct link to download to the garmin but it doesn't work well or something I do wrong. Are there other options to upload tracks? Thanks in advance.

    1. Achieved, with wikiloc, but EYE not with Chrome browser, better internet explorer because of problems with plugins. Other options is through Garmin Training Center.
      A greeting from the swains

  37. A very complete analysis. I have a couple of "problems" to consult with you. With the strava segments active, in the segment options I don't have the tab to activate the turn indication. The other problem is that the paths, even if I have the turn indication activated, don't indicate them to me. How do I solve it? Thank you.

    1. I don't know what you mean by your first question.

      For the second, creating the route from Garmin Connect does not include turn prompts, so you would have to create the route in other applications, such as RideWithGPS.

      1. Hi Eduardo, thanks for your answer. In the first question, I mean that in the segment options, I don't get the tab for the turn indication option, when according to the manual, I should get that option. It only comes out Search, Activate/Deactivate and Delete. Thank you very much

        1. Well, I don't usually mess around with the segments much, and I don't have an Edge on hand right now, but it wouldn't be the first time that something that appears in the instructions (or web description) is not on the device.

  38. Hello
    Very good article!!!!!, I have a doubt about the strava segments, when you start one and during the same puts you in real time to the time you go from your personal record (which you have done before) both above and below it or only puts you when you finish the segment?
    Thanks for the advance.

  39. Hi, very good analysis of the equipment, I have it a couple of months ago and it works perfect, the data of the maps was very useful to me. Anyway I missed you commenting about the "recovery" mode that it brings in 520...once the training session is over it sends you a calculation of the recovery time (in hours) that you should respect for a next session. It is this topic that has brought me to the page, I would appreciate if you had info about it (how it works, if it is configurable or not, or other tips).
    Greetings, Miguel

    1. It's similar to the same functions found in Garmin watches (I'm sure I've talked about it in more than one test, but now I can't tell you which one by heart).

      It is simply an indicator to avoid overtraining. It does not mean that you cannot exercise again in X hours, simply that it is not recommended that you return to high-intensity training in that time frame. That is, do not do high-powered or interval training on consecutive days.

      1. Thanks for the answer, Eduardo, greetings.

        Without further ado, yours faithfully, Miguel Ojeda P.

  40. Dear; I am starting with the Garmin 520; no doubt I have a long way to go. Yesterday I tried it in cycling and I am completely satisfied. I would appreciate your help regarding how to try it in Spinning as well; I share it with my wife, and we are interested in managing the heart rate of the Garmin for Spinning; what is the best way to use it?? Indoor ... With some APP that recognizes the heart monitor ... I would appreciate your opinion

    1. It can be used in the indoor mode connected to a pulse sensor, but if the bike does not have any kind of sensor there will be no distance or speed information.

  41. Hello, Eduardo. My name is Joaquín. Thank you for your magnificent explanations. I'm starting the season now, I need to set my scores to zero. How do I do that? I can't find the way to do it. Thank you very much for your help.

      1. I want to differentiate the data from one season to another. I'm sure it's very simple but I don't know how to do it. In the device I have the option to delete all the data from the device and the activity profile is here? Thank you

        1. You can't have "seasons". All you can do is delete records (records, FTP, etc). But once deleted, it disappears.

  42. hello, great tutorial and great team. i've had it for a year and i'm very happy. the problem is that i program a screen to control a path that i previously entered, and the garmin doesn't give me the data correctly. i thought that in later updates it would be fixed but it's still the same. it's a common problem? greetings

  43. Hello Eduardo, my name is Jorge. I bought the device today and tomorrow I'll have it at home.

    I have tried to download from the web that you indicate the most detailed map (in my case, the Valencian Community) but when I open the mail with the download link I don't see the one you indicated in the article (the one with the micro SD), I see a .zip with the icon of a penguin... I don't know if it is that one... I have tried it several times and nothing... Let's see if you can solve the doubt.

    Thank you for this great article and your help, a greeting!

  44. Hi, thanks for the test you're doing. I have a question: I have to do a night run with my 520 and the other day I tried to follow a track at night, but the screen turns off after 4-5 seconds. Is there any way to keep the screen on all the time? Thanks!

    1. Yes, you can leave it always on (this is what I do regularly when I train at night, which is almost always). In the brightness setting, you have a duration option where you can set it to always remain on.

  45. Hi, Eduardo,
    First, great entry, the most complete I've seen. I've been going over the features of mobile connectivity and I think the next one is not included:

    "Connect your cell phone to the gps so we can send you the routes (gpx)"

    This comes in handy when you're on a trip and don't have the computer to put the track in.

    I have seen that for some models it is possible to buy an OTA cable (male usb) to make the phone behave like a pc and be able to see the gps folders to put the gpx file.

    Do you know anything about this?

    Thanks in advance.

    1. Yes, it would be possible. The Edge would be put into USB mode and its entire memory could be accessed from the phone.

  46. Good morning.
    First of all, congratulations on the tutorial, which I think is the most complete one you can find.
    I would like to count on your experience to try to solve a question that I can't find anywhere else, even though I have looked for it. I bought a unit taking advantage of the discounts of the black friday, and when I start the gps I CANNOT PUT IT IN SPANISH. I have spent a thousand and one times all the languages that the equipment has, thinking at first that I was crazy and I couldn't see it... but in fact, it DOES NOT COME IN SPANISH. Is it normal for a device that brings the instructions in Spanish?
    Does anyone know if they have any kind of solution to update the latest version or anything like that?
    Greetings and thank you very much

    1. Connect the Edge 520 to your computer and check which languages you have installed in the "Text" folder. They should all be there.

      1. Hello Eduardo, as always following your blog with the best explanations of Edge 520. Every day I use it, I think it's a totally successful purchase. Now, taking advantage of the 60 days of Premium on Strava, I have two doubts about the segments:
        1) When a large segment, let's call it from points A-C, has a middle point B. How does Garmin detect both segments (A-B, then A-C), is this possible, or do I only have to deactivate one segment to be able to run one at a time?
        2) A mountain segment. It only has one display screen, or there is also a map view of this segment (see distance and height traveled v/s distance and height remaining).

        I await your news, and greetings again

        1. It only shows one segment, and it will be the first one to start, so if there is a 1km segment and in the middle another 10km segment starts, it won't show it either (unless you discard the first one before the start of the second one)

      2. Hi, Eduardo.
        I have checked the "Text" folder as you indicated, and there is no English or Spanish file. Is there a way to download it and enter it or what other solution can there be?
        Is it normal that he doesn't come?

        1. No, normal is not...

          When I use the Edge 520, I connect it to the computer and I send you the text file with the language. You simply have to put it in the folder in question

          1. Thank you, Eduardo.
            How can I give you my email address?
            I need the gps for next week, I don't know if you could get a second one at some point to send it to me.
            Thank you very much again, it's nice to be able to count on knowledge and always ready to give a hand to the less experienced.
            Greetings

          2. I got your e-mail, the one you left the comment with. See if I can make it tonight, I'm out right now.

          3. Good morning Eduardo, congratulations for the work you present us, I spent 15 days "playing" with the 520 until I met you,
            A simple question : is it possible to calibrate the room temperature ? I think it gives me a couple of degrees below the real tempe,

            Thank you very much and best regards,

          4. No, the temperature comes exclusively from the internal sensor, and as in every thermometer, it also depends on whether it is sunny or "cooled" by the wind, etc.

  47. A couple of questions. Where's the temperature "sensor"? ...some say it's where the serial number is, the hole you see there.
    And secondly, it happens to you that with the auto pause activated you suffer cuts (pauses) when you are at full cruising speed?

    1. That hole is for the air pressure sensor, for the altimeter. The thermometer is inside the device, it does not need an "outside" socket.

  48. Hi, Eduardo,

    Thank you very much for the comprehensive analyses you do, they are tremendously useful.

    The last Kings gave me the Edge 520. With the device in question everything is perfect, however I have problems using the Garmin Connect application, I do not know if you can help me with this.

    On the evening of the 6th I downloaded the App, went in and clicked several times on the 'create account' option and accessed the part where I had to fill in the data. Between hitting the right username and how distracted I was, the day went by, I didn't get to create the account and left it for the next day.

    Well, since day 7, when I enter the App again and then click on 'create account' it only takes me to a page with a dark blue background without the possibility of filling in any information. The same happens if I click on the option 'login'.

    Given the situation, I created the account via the web, but it's not much use to me because I still can't get past 'create account' or 'login' since, as I say, all that appears afterwards is a dark blue and empty screen. I've uninstalled it and reinstalled it several times and nothing. I have a Sony Xperia Z3 (from June 2015) in case this detail helps. I hope you find the key and can help me because the use of the App together with the device is quite important.

    Thank you very much in advance.

    A salute,

    Thomas

        1. Hi, Claudio,

          Thank you for your comment. In any case, the solution was not what you proposed since I was able to create my account via the web. But, once created, when I accessed the App and after selecting 'create account' or 'login' indistinctly, it took me to an empty page with a dark blue background and without any possibility of doing anything, except go back. In my first comment I detail the problem and in the second, in which I answer Eduardo, I mention the solution that they gave me from Garmin, in case it helps someone.

      1. Hi, Eduardo,

        Thank you for taking the time to read my comment. Finally, Garmin responded and solved the problem. I share the solution they gave me in case there is someone who has the same problem, since, from what I saw in the comments about the App inside 'Play Store' there were many people in the same situation. In short, you just have to update the 'Android System Webview' application that comes standard on Android terminals and then restart the device. Once done, you should access Garmin Connect without any problem, either to create an account or to log in.

  49. Hello, Eduardo, again, thank you very much for your magnificent analysis.
    Could you tell me, if there is any page or site, where I can find information about what the data on each screen means?
    There's half that I don't know what they mean.
    Power - IF
    Power - kJ
    Maximum power
    Average power
    Power - NP
    Power - TSS
    Etc.
    Thank you very much and congratulations.

  50. Hello good morning congratulations for the web and especially for this analysis, I've never seen something so conscientious. My doubt is about installing the maps through openstreetmaps.I live in Madrid and I frequent the north mountain range, I follow all your instructions, but when I introduce the file in the edge 520, it weighs more than 400 megas and tells me that there is no space, what am I doing wrong? Thank you

  51. Hello Eduardo and congratulations in advance and thank you.
    I bought the 520, and when I turn it on, it's like it's looking for satellites. None of that 30 seconds it takes you. Do you have to configure something or is it just bad?
    Thank you again.

  52. Hello Good morning, first of all congratulations on the review, it's a great job. Even better than the help on the Garmin website. I had 2 questions:

    1- When I try to download the maps of my area as you indicate, it tells me that the weight of the file is bigger than the memory and I cannot pass it, any solution?

    2- how can i make the 3 months of strava premium worthwhile?

    Thank you very much.

    1. You're trying to download too big a map, select fewer fields.

      When you synchronize Strava with Connect the option should appear in the dashboard, if it doesn't, contact Strava.

  53. Good afternoon Eduardo, congratulations, it's the best review I've seen so far. I have a problem to see if you would have the solution. When I do a programmed training on the garmin website through the 520 and the bkool roller, I adjust the resistance of the roller for example to 10%, but when it goes to the next step I remove the resistance and put it to 0, I have already searched and searched and I see nothing.

    Thank you very much.

    1. You should contact Bkool at info@bkool.com and pose the problem to them, because it's more related to the roller than to the Garmin, which ultimately only sends commands.

      I usually use the 520 with a Tacx roller without any problems.

  54. Hi Eduardo, I just bought a 520 Pack and I have doubts about the importance of the speed sensor; is it really necessary for road use only?
    Today I have launched the 520 without the speed sensor and it has measured my speed and distance well at all times (compared to a colleague who was driving with the sensor in the hub)
    Do you recommend putting it in or is it an expendable item?
    Thank you very much for your attention.
    Greetings

    1. On the road it is not so necessary, but if you already have it I would use it. Tunnels, bridges, areas with trees... at all times you will have a real speed. The GPS will normally give you accurate data, but there will always be times when it can fail.

      1. Thank you, Eduardo. I think so, I'll keep it at least I can use it in mountainous and wooded areas with less coverage.

        Very kind. Thank you!

      2. Hello again Eduardo, A consultation; to be able to visualize in the Garmin the RP or best time of a friend when I go through a segment that I have marked with the star of favorite in Strava, I must be Premiun or there is something that I have not done well?
        I don't get that in any of the segments I go through.
        Thank you

          1. Hi Eduardo One last question; I am already a premium and when I go through a segment and the time comparison is activated, I only see the positive or negative time differential and what is left of the segment.
            Can't I put other data on that screen, like the heart rate monitor?

            Thank you

            Get Outlook for Android

          2. It's been a while since I've had a look at the Edge's configuration, but I seem to remember that Garmin hasn't made any changes to it.

  55. Hi Eduardo, the inclinometer is behind me with respect to reality, I mean the % slope does not really mark where you're going, but is a few seconds late, you're going down a peak, I still mark me as I continue to climb, and the altimeter every time I turn it on goes to mother and I get to put the altitude by hand.
    Greetings and thanks in advance

    1. It is normal, there is no inclinometer, but you have to go from A to B to interpret the data. The same with the altimeter, it is based on the atmospheric pressure and it is not a constant. What it measures is the altitude variation, but it is not radar.

  56. Good afternoon, Eduardo:

    I'd like to see the altitude graph at the bottom of the data field, like in the polar ones. Is it possible to do this with one of the Garmin? I know it's possible to see it in full screen but I'd be more comfortable seeing everything on one screen.

    A salute.

  57. Good morning, I wanted to ask you something that may seem obvious, but I have not found the solution; when I follow a route on the map, which I have previously entered, I have not been able to return to the data screen without interrupting it, that is, if I follow a route downloaded from wikiloc, for example, I can only use the computer to follow it, and I cannot check the time, kilometres travelled, clicks, etc....

    1. I don't understand what the problem is... in navigation you simply add the specific screens, by pressing the scroll buttons you should be able to return to your usual data screens.

      1. I see that I failed to indicate that the problem arises when I remove the automatic zoom and switch to manual, because to follow paths and roads in the mountain, which is what I use it in gps mode, I have to zoom in, and I do not return to the data screen. Probably there is no solution since the scroll buttons are overridden.....

        1. Of course, you're not on one screen, but you're changing the zoom. Until you select the zoom you want to see, you can't logically go to another screen.

          1. Solved! I had not fallen in selecting the zoom, thank you very much for your response

  58. Hello, first of all thank you for the test, then a question that comes up.
    We have three 520 and we have noticed that when we go out, it gives us a different accumulation ( for example in 1000 meters it can vary 100 ) and we wonder if the placement in the advance support has something to do ( if it has to do with some inclination of the support ). Thanks again

    1. No, it has nothing to do with that. It is simply a barometric altimeter and depends on the pressure, the initial calibration and how the sensor works in each of them (dirt in the port, etc)

  59. Hi, great analysis!

    I wanted to ask your advice: I have to load the tracks of a race in my 520 and the organization gives us 2 options of gpx files: some complete tracks of about 700kb each one or the simplified version of about 250Kb each one... with which do you think the device will work better? It can go slower or hang if I load the heaviest ones... (of memory I go well because my maps are 45mb)

    Thank you!

    1. Twice I downloaded gpx routes from Strava (size 700-800Kb) and both times the device hung up on me, while the ones I downloaded from wikiloc 100-200Kb never had any problem, I don't know if it has anything to do with it?

    2. You should have no problem with full tracks. Simplified point tracks are for older devices.

      1. Thank you!! I was hesitant because twice I downloaded gpx routes from Strava (size 700-800Kb) and both times the device hung up on me. On the other hand, the ones I downloaded from wikiloc 100-200Kb I never had any problem, but I guess it was some problem with that particular Strava file. Greetings and congratulations for your analysis!

  60. Hello, Eduardo, thank you very much for your patience and kindness.
    Some time ago I bought a potentiometer of only the left crank. In the G 520, specifically in the POWER screen, there are several groups like the average Power 3s, average Power 10s and average Power 30s. Which would be the best to see the watts, the 3s, 10s, or 30s.
    Last question, to see the % of force that I do with the left leg, what screen should I put? I don't know if, balance, effectiveness of the torque, fluidity of pedaling, etc.
    Thank you, thank you, a thousand.
    Greetings, Xavi.

    1. I personally like to wear the 3s and the 10s.
      Power at 1s is too variable to take advantage of the data and for longer averages, I prefer to use averages per lap.

      As for the other thing, keep in mind that your meter uses the power of the left leg and multiplies it by two. Therefore there is no possibility of obtaining separate data by leg or other metrics. Only power.

      1. Thank you very much. It has been very helpful. I got the wrong Inpower, what I needed was to have both legs marked or one. The guy who sold it to me said he would mark my left leg, and that was enough for me. I have osteomyelitis and for that reason I pull more from one leg than the other. What I want is to constantly correct, to make strength with the underdeveloped leg.

        Thank you very much, for your patience and above all your kindness.

Hello my question is as follows, someone could tell me how I can add to the odometer the kilometers I had in my previous garmin, because when you buy the 520 the odometer starts from 0 and I would like to introduce the kilometers that were already done, to see if anyone knows and can explain.

    Thank you

  62. Good afternoon I bought a Garmin 520 and when I stop pedaling the cadence marks 0 and when I start pedaling again I get a pause and play screen. It's normal
    I don't know if it's misconfigured.

  63. Hi, Eduardo;
    I have a 520 that works perfectly except for the unevenness. I go through ports with good weather (without clouds) and without excessive vegetation above (which makes the satellite difficult) and I do not mark correctly the unevenness in the climb. The same marks me well that it stays at 0% when I go up.
    I put the GPS + Glonass and I still don't have the right level.
    I have a cadence sensor on the rear wheel.
    Thank you in advance for your response

      1. Hi Eduardo The barometric sensor is not covered by the cover. I don't know if I can clean it somehow but apparently it's not blocked

        1. Good afternoon; if it works for you, you should update the Edge 520 SW. The previous version had a problem with the % tilt or slope measurement. Maybe that's where the problem lies. I'm sending you an image with the SW change history where you can see the above.

          Greetings

        2. I mean the port itself. It may be clogged with dirt. Anyway, check out what Claudio said about the software update

  64. Hi, Eduardo!
    A friend is looking for a gps that will serve him both for cycling, his main sport, and for hiking in the mountains.
    You asked me about this Garmin, would there be any chance that this 520 would work for both sports?
    If not, which I guess, what gps would you recommend?
    He wants me to guide him through the mountains, but also to have a heart rate monitor, a cadence...

    Thank you very much in advance for your great work.
    Greetings

    1. Serving for mountain would do, although it is not the most comfortable thing to carry in your hand and probably the navigation will be quite short.
      Especially if you're thinking of a similar navigation to the one offered by the Foretrex...

  65. Thank you very much for your response!
    What GPS would you recommend for both uses? Biking (measuring cadence and pulse) and hiking.
    Could you manage with a 520, 820 or 1000? and if so, which one would you recommend?
    or both, an etrex 30?
    I'm very lost on the subject.
    I've had a look at the foretrex and it seems to be going pretty good.

    I bought the 1000 last year through one of your offer links and I'm super happy, but I only use it for mtb.

    Thank you and a greeting

    1. With an 820 or 1000 you could manage very well on the bike and something more regular to do hiking routes.

      The perfect Etrex for handheld navigation, but it does not support sensors and cannot be mounted on the bike. It already depends on the profile that will be the most used.
      If it is mainly for the bike, an Edge that can be mounted on the handlebars without problems.

      1. Hi Eduardo, let me add something. I have the Edge 520. I added from Garmin IQ connect the Hike2 application and bingo. It all worked out ok. I logged the hiking session and having the Garmin account synchronized with Strava, it gave me perfectly all the information in this application. Greetings

        1. Good input. Yes, it's certainly worth taking a look at all the Connect IQ applications because we can always find everything we're missing on the device.

  66. Hi Eduardo. First of all, I want to thank you for the analysis of the product you are doing. I would like to ask you. Between this Garmin Edge 520 and the Polar V650, which one would you take? I do MTB and I like to load routes from wikiloc. I have the polar speed and cadence sensors, because they were given to me for my birthday and I used them with the V800 until this one broke down.
    Thank you very much.

    1. The Edge 520 is a far superior device, in every respect. Even if you can't use your current sensors, but there isn't one feature where the Polar is better than Garmin.

  67. Hi! Do you think that for 252 euros that is on Amazon (the pack) is a good offer? It is for a gift, and I don't know if I should choose this one or pay 100 euros more and buy the 820.
    Thank you!

    1. For 252 euros, being the pack with sensors, it is a good offer. As for opting for another model, only if navigation is one of the main functions.
      Otherwise the 520 is very complete and the basic navigation functions are sufficient in the 90% of the cases.

  68. Thank you for your magnificent clarifications ... I have a doubt ... I have the 520 and I want to catch the cadence and speed sensors ... and I have said that automatically adapt to the bike, I explain, as you know the speed sensor that type of wheel is ... as calculated, I am not clear ... because my idea is also to change from a mtb to the road when you take one or another ... and I have doubts that mark the values well ...

    All you'd have to do is change bikes and just adjust the wheel...? What's the basis...

    Thank you very much for clarifying.

  69. Hello, incredible work, I have a doubt, I have acquired the cadence and speed sensors, the thing is that I want to use them in the road bike as well as in the mtb. The doubt is... they adjust themselves only by riding with them in one bike or another when they have ridden a few meters... And another thing... would that adjustment be recorded in the different profiles that I have in the 520? In this case one of mtb and another of road.

    Thank you very much. I hope you can clear this up for me.

    1. On the Edge 520 there are no more profiles, but as for the sensors, yes, there is always automatic adjustment (if you select it) at the first moments of the output.

  70. Good night, and thank you for working so hard on these reports.
    I'd like to ask you a question, I have a Garmin eTrex 35 that I use for both hiking and MTB routes, now I'm thinking about getting my hands on the speed and cadence sensors and I've seen some ads from people who sell them but say they're from the Edge 520, could you tell me if they're compatible? I can't find that information anywhere.

    Greetings from Seville.

  71. Hello, I have brought the kings 520 and I have a question, when you're in a segment and you're in the map option that you comment (the first, not the virtual partner) you have two data screens, I think you can modify in the data screens, map and tells you data fields segments and you have 2.
    Greetings and thank you very much for sharing your experience

  72. Good morning, thank you very much for the thorough analysis.
    I just bought a Garmin EDGE 520 but when I use it on the roller the speedometer works very intermittently even though I am constantly moving zero speed appears, as if the speed sensor was not detected.
    Is this normal for indoor training?
    Besides changing the battery what options do I have to correct this issue?

          1. I'm the same, but in my case the GPS is a Garmin eTrex Touch 35, with the original Garmin Speed and Cadence sensors. The cadence sensor is working very well but the speed sensor doesn't show me anything, the GPS detects it but the speed is always in 0km/h. I have sent the GPS and the sensor to Garmin and they tell me that it works correctly, but it doesn't show me anything

          2. It can also depend on the calibration, has the self-calibration been done outside?

          3. Today I have done a route of almost 50 kms and nothing at all, I mark the speed indicated by the gps, but if I put the Garmin in Demo Mode (which does not detect any gps satellite) the speed sensor does not mark anything.

          4. Already used outdoors and manually calibrate the tire size. Ever seen problems with this sensor?
            Now in the evening I will change the battery, if I find any solution I will tell you.

          5. I've had this problem since the beginning, it's never worked well for me, maybe it's a configuration fault if that's the case and someone knows how I'm going to comment on it because otherwise it'll be money thrown away.

          6. There's not much to set up, just the default wheel size which is set to automatic and is automatically calculated in the first few minutes of an outing where GPS is used. If a speed sensor is connected, its data will be used to calculate speed and distance, and if there isn't it switches to GPS.

            Check that the sensor has a battery, its operation is based on an accelerometer so it is possible that it has run out of battery in successive transports, movements, etc. before the final sale to you is completed. The status LED must blink for 5 seconds when starting the movement to indicate that it has entered into operation.

          7. The sensor is completely new, but I'll try to change the battery, of course I've measured it with a multimeter and it gives good voltage.

          8. Good morning, I told you that I managed to get the sensor to work correctly, I did several things that possibly helped this solution, I don't know if all or only one of them helped.
            1. Disconnect and remove from the GPS sensor list and perform the reinstallation
            2. Manually setting the rim dimension
            3. Uninstall any apps you download from IQ CONNECT
            4. Use the preset displays not the IQ CONNECT
            5. Use the distance meter on the display and not the mileage meter

            I'm not saying that IQ CONNECT's APPS are bad, nor do I mention the ones I downloaded out of respect for the developers, I'm just stating what I did and that it now works at 100%.
            Greetings

          9. I'm sorry, I didn't quite understand your explanation. What does the app have to do with the GPS not detecting the speed sensor?

          10. Download IQ CONNECT apps to use for displaying GPS and sensor data, I really don't know what the calculation criteria are or how they analyze or quantify the values generated by the sensors.
            When I had problems with the speed sensor I was using an IQ CONNECT app and not the GPS preset.

          11. I think we're talking about different things, I use the app for after the exercise.

            In my case I link the speed sensor to the GPS, I pedal and the GPS display shows 0 km/h.

            I sent both the GPS and the speed sensor to Garmin and they have sent it back to me saying that it works perfectly, however I can't get it to go right.

  73. Hello Eduardo, taking advantage of the offer, I have acquired the 520 pack following the link. Being a cyclocomputer suitable for training according to the price, I would like to know what potentiometer you recommend without great pretensions, simply to record the improvement achieved in the training. A greeting and thanks.

    1. My recommendation is always a meter that is powered in full, or separate on both legs. I do not find it interesting to measure one side only and multiply because it can be misleading.

      I personally use the Assioma Duo pedals

  74. Hi Eduardo, what an incredible review! The truth is that the 520 seems to me super complete and the best thing is that it doesn't have the problems of a touch screen like the 820. The big difference that I feel is important for me, is the height profile adjustment that can be done with the 820, I haven't been able to check if the 520 allows it. That is to say, changing the vertical and horizontal scale in the height graph. I appreciate it if you get me out of the doubt to make a decision.

    1. You mean the one it displays during navigation, right? Garmin refers to as "dynamic zoom," but all it does is put what fits in that space on the screen. But it doesn't allow you to change any kind of scale so there's room for more or less information.

  75. Greetings, thanks for the reviews, you solve our life. A question from 520: how can I change the fields that appear when I am completing a segment in strava, is it from 520? or from garminconnect? and how do I proceed? thanks

      1. Indeed, those are the fields I want to see, in the garmin 935 that data is what I see but in the 520 I get the map without being able to modify zoom and the two fields are average speed and the other one I don't remember but they are not useful, and when I saw in the review that the fields were different from mine I tried to modify them but I don't see any way, could be due to the last update?

        1. I don't have a 520 anymore and I can't check it, and in the ones I have right now around here (Edge 130 and Edge 1030) the Strava screens are different so it's not applicable...

          Maybe the possibility was added with a firmware update. Check in the profile options where the autolap configuration is, etc (not in the data fields)

          1. Ok, I'll check it out and comment on it in case it's useful for someone, thanks a lot, if I manage to sell the 935 my purchase of the 945 will be around here.

  76. Hi Eduardo, I've only been doing mountain biking for a year and I started doing road biking a month ago.
    Since I started, I use my POLAR M400 (before it was more of a runner) to record my activities. It makes me feel at ease, but I'm starting to appreciate buying a computer. Several cyclists in my environment use the GARMIN EDGE 520 (so I've read it's the one you use). I'm super busy because I've seen that there are several versions (plus, pack, mtb ...) and I read that some were even discontinued.
    I would like to buy the GARMIN EDGE 520 pack (which comes with the band for the pulse, the cadence, a fixation for the mountain bike and another for the road bike...) but I don't know how the market is at the moment as there are other models that offer other features as far as the device is concerned.
    Anyone who's bought it recently? What ratings can they do? Good, nice, cheap?
    Thank you, all of you.
    Greetings.

    1. At this point I would opt for the Edge 530. It's a bit more expensive, but it's quite worth it not only for the extra features, mainly the processor speed (day to night).

      Currently I don't use the Edge 520 anymore, I now go out with Edge 1030 or 130 to compete.

  77. Hey, how about Eduardo?
    I've read five times all the review you've done of the 520, and for those of us who come from the mythical 705, it's really great.
    There goes my question. I have a slight doubt about the battery, since putting the lighting to 0% and only activating GPS, using only a FC band. In outputs of one and a half hour the battery is already at 65% (mountain) and in outputs of more than two hours on the road I get home with just a 46%.
    Is it normal that I consume so much, do you think that by changing the battery I can extend the life of my outings?

    Thank you

  78. Hola… El artículo es el más completo que he visto. Tengo una pregunta. Cuando hago sesiones de entreno indoor, con el sensor de velocidad reconocido, por qué no me salen los kilometros y la velocidad bien… La velocidad varía entre 0 y 0.5… Como se programa para que salga? Muchas gracias.
