Issue installing application on Garmin Forerunner 955

Hello

I would like to ask why I am unable to install my application on my Garmin Forerunner 955.

With my previous device, the Forerunner 235, I was able to connect the watch to my computer and simply drag the application into the “data” folder.

Is there a simple or recommended method to install the application on the Forerunner 955?

Thank you in advance for your support.

Kind regards

  • You still do that, but it's a bit more complicated. What OS is on your computer? Do you see the files on the watch?

  • If you are using macOS, you need a 3rd party app like OpenMTP to manage files on most newer Garmin devices: https://openmtp.ganeshrvel.com/ 

    If you are using Windows, you can use File Explorer to manage files, same as on older devices (albeit with a few limitations, like not being able to directly create or open files on the device). (e.g. if you want to create a .txt log file to go with your app, you have to create it on a different drive and copy it to the device; you can no longer create such a file directly on the device from file explorer).

    In both cases, you copy the app PRG to the \GARMIN\APPS folder.

    EDIT: either way, you must completely close Garmin Express beforeattempting to access files on the device. (Including closing the Garmin icon in the Window notification tray or macOS menu bar.)
