Hi,
I have a GPSMAP62S.
I updated the firmware to Ver2.44 using the Garmin Webupdater.
Unit works fine but the altimeter on the unit always give a elevation of 20.000 meters.
I have manualy calibrate the barometric altimeter with the correct elevation but after a few seconds the altimeter gives an elevation of 20.000 meters.
Also after a factory reset the elevation stays at 20.000 meters.
Anybody any ideas?
Thank you!
