This article was originally written for the Garmin Fenix 2 update. However, the procedure is the same for any other Garmin Fenix 2 device. You can follow the same instructions if for some reason you have or want to perform the update manually, rather than through Garmin Express or wirelessly.
I recently received a new device for a full scan. It is the fantastic Garmin Fenix 2. And as you should always do as soon as you receive a new watch, the first thing to do is to update it to the latest firmware version available.
And that's where I was, when I got the first one on my forehead. Garmin Express was determined to tell me that my Fenix 2 was not compatible with the application, and to use Garmin Map Updater. Impossible, because that program is intended for other types of Garmin devices, and not for watches. This error occurred on all the computers I tested, regardless of operating system. Mac 10.9, 10.10, Windows 7, Windows 8.1...
If I couldn't synchronize it with Garmin Express, how was I going to update the clock? And I had to, because it came with version 3.50 and at the time of writing this entry we are already in version 4.00. The next thing I tried was WebUpdaterThe program correctly recognized the clock connected to a Windows 7 computer (on a Mac I couldn't even see it), but after downloading the update, it indicated that the file was not correct and cancelled the installation.
After a few heads against the wall, I decided to study the way Garmin does the update, to find some solution to the problem. After a couple of minutes checking the memory of the clock, connected as USB storage, and reading a couple of links in Google, I saw that the program what it does is to pass the update file to the internal memory and once copied to its folder, it sends a command to the clock to restart it and start the update. So I was going to do the same, for which I was going to need the update file.
And where to get it? It's easy, you just go to the update for the Garmin Fenix 2and right-click and select "view source code". In the first lines you will see directly the link to download the update, which in this case is: http://download.garmin.com/software/fenix2_450.gcd. Surely this step will save you podrue, since the most normal thing is that if tomorrow the update to 4.30 is released, the file name will simply change to fenix2_430.gcd, and therefore modifying the download link will be more than enough. But just in case, there you have the way to get it.
Once you have the update on your hard drive, all you have to do is change the file name, from fenix2_420.gcd to GUPDATE.gcd, then connect the Garmin Fenix 2 to your computer in USB storage mode (as a hard drive).
Go into the /Garmin folder, and copy the GUPDATE.gcd update file to that location. As I mentioned at the beginning, we are doing the same procedure as the update software, so once the file is copied, the next thing to do is to restart the clock. Press and hold the "Light" button and in the menu that appears select turn off, and then turn it back on with the same button. And this is the screen you will see.
Once the clock starts, the update will begin. Don't worry, because before installing, first verify that the file is correct and not corrupt.
After validating the update, the installation process begins. The first message you will see is "Loader". The watch is loading a small program that will be in charge of installing the update.
The update continues.
And after preparing the Garmin Fenix 2 update, the loading of the new firmware begins.
After completing the installation (don't panic, it takes 2-3 minutes, patience) the clock will restart, so the first thing you can do is go to Menu > Settings > System > Envelope and check the information. Indeed, you already have the clock updated to the latest version.
No data or settings are lost in this update (just like in the "official" process). And all this without having to install any intermediate programs.
