Welcome to, my name is Dustin.
I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.

Expert:  Dustin replied 25 days ago.

Usually, we just need to reset the devices internal software to solve issues like this. Heres how to do that

To perform the master reset:

  1. Power Forerunner off
  2. Press and hold Mode and Enter buttons
  3. Press and release Power button (still holding Mode and Enter)
  4. Release Mode and Enter once Power is released

The reset on the Forerunner 910XT is successful if the device finishes powering up and goes to the setup wizard. Try the steps again if the setup wizard does not appear.

Leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data once the reset and setup wizard are complete.

Once complete, test the device.. If its still not reading ri ght, let me know and we can try other steps as needed.

I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied.. I always answer follow up questions.

Will I lose all my data and have to setup all my screens again?
Expert:  Dustin replied 25 days ago.

You will.. But thats the only way to "right" the software.

You could use garmin connect or express to backup your data first..

I just wanted to avoid setting up my screens again.
Customer: replied 25 days ago.
I'll do the reset. I'll know tomorrow after my ride if it works.
Expert:  Dustin replied 25 days ago.

Understood.. It might be a good idea to connect the device to your computer, and then update the software through garmin express as well, before your ride.
