Update any Garmin. Manual procedure.


Esta página está disponible en español

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 2, y pinchando con el botón derecho seleccionar «ver código fuente». En las primeras líneas te aparece directamente el enlace para descargar la actualización, que en este caso es: Seguramente este paso te lo podrás ahorrar, ya que lo más normal es que si mañana sale la actualización a 4.30, el nombre de archivo simplemente cambiará a fenix2_430.gcd y por tanto con modificar el enlace de descarga será más que suficiente. Pero por si acaso, ahí tienes la manera de conseguirlo.

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).

Entra en la carpeta /Garmin, y copia el archivo de actualización GUPDATE.gcd en esa ubicación. Como te comentaba al principio, estamos haciendo el mismo procedimiento que el software de actualización, así que una vez copiado el archivo, lo siguiente es reiniciar el reloj. Mantén presionado el botón «Light» y en el menú que aparece selecciona apagar, para después volver a encenderlo con el botón mismo botón. Y esta es la pantalla que verás.

Once the clock starts, the update will begin. Don't worry, because before installing, first verify that the file is correct and not corrupt.

Tras validar la actualización, comienza el proceso de instalación. El primer mensaje que veréis es «Loader». El reloj está cargando un pequeño programa que será el que se encarga de instalar la actualización.

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.

En esta actualización no se pierde ningún dato ni configuración (igual que en el proceso «oficial»). Y todo ello sin tener que instalar ningún programa intermedio.

      1. Ola Eduardo, first thank you very much for your time, of course the bluetooth has been turned on, before it was connected and transferred the data well everything started on the day I started the Garmin connectet session on the pc. From that day on they no longer uploaded it between us, before I only did it with my smartphone, and in the month of December I was in the navigation mode and the clock stuck did not do anything, perform the procedure to unblock it and restart it, and from that day the option to synchronize does not appear in the menu. I waited for your comment and thank you very much

        Kind regards

  5. hola profa ayuda despues de realizar todos los pasos el reloj se cuelga en validating update que puedo hacer para solucionar este problema porfa una ayuda

    1. The process is the same as if you were upgrading from Garmin Express. There is no danger to the clock. If after a few minutes it doesn't go beyond that, force the shutdown and try again.

  6. Good afternoon, I have the garmin fenix2, and for certain reasons, I had it in disuse for a month and a half approximately, after this time, I reconnected it to load,,, and my surprise was that it turns on but it doesn't load, it stays in 0%...
    Does anyone know anything?
    Thank you very much in advance

    1. Leave it connected and charging for several hours. If it does not start to build up battery charge, it is a battery failure.

      1. Hi! I tried to do a downgrade with this system of my garmin 2, and it did the whole process that you descend, but at the moment of starting it the screen remained black, but blinking slightly, and it doesn't come out...

        1. You probably can't download a version determined if there is a difference in the bootloader

          1. Thank you, Eduardo, but then, it's my turn to send it to Garmin?
            Or do you know if there is an option to connect it and put the current version in?
            Thank you

          2. If it doesn't connect to the computer anymore, you won't have anything to do

  7. Hi, I accidentally formatted my Garmin Feniz 2 on a Mac. I managed to reset it by formatting it in Windows and it's visible on the computer. The garmin works, it reloads the system files but says it has low memory and can't possibly recognize the change of language and so on after initialization. Apparently when it starts it doesn't read the XML files or can't see the partition where the data is.

    Any suggestions?

    1. Well, apart from forcing the update from the watch's own memory, I can tell you little else...

  8. hello i bought a fenix two but it doesn't give me the actual temperature where i update that theme and the barometer is still not accurate

  9. Bravo – worked for me. Just copy paste the file into the Garmin folder and boom it works. Thank you so much.
    I deleted also the tracks and GPS coordinates saved – maybe also a source of error.
