Thread: Problem with Garmin dezl 770LM warning message high temperature and shut down

I have Garmin Dezl 770LM with problem .

When power on GPS after loading to home screen i see message " shutdown to prevent damage due to high temperatures " and navigation counts down 10 seconds and turns off.

I don't test replace firmware because I need the saved points in the navigator.

When garmin show logo connect DATA cable and enters PC connection mode for 10-15 seconds and automatically turns off. This time is not enough to add it to Garmin express.

Spoiler: small unnecessary picture
