The DEM altimeter calibration does not work since the release (for me). I have mentioned it in some threads, but all threads have been deleted at once (or I am not able to find them anymore).
System>Altimeter>Calibrate>
@Garmin, are there any plans to fix it? Otherwise you should remove this functionality from fw, if you are not willed or able to fix it. Or is it only my device and working for all other users?
