I was entering a waypoint in my etrex h when suddenly, the screen froze. The buttons didn't work anymore (even the power button).
So I shut it down by removing the battery.
I turned it on (the power button worked then).
The start menu loaded and after this the satellites screen appeared. The satellites tracking worked.
However, once again, the different buttons (page, power, enter, up and down) didn't work at all.
After shutting down my etrex, I tried a master reset by pressing the page, enter and power buttons.
The menu asking if I really want to clear the data appeared, but I could not confirm anything since the up and down buttons didn't work.
Can anyone help me with this?
