[docbog]

2014 GMC Sierra, about 65K miles.  Home is in PA, now on RV trip in Florida.  Yesterday Navigation thought I was in a Lake !  GPS needs "calibrated" - any ideas ??  Thanks in Advance, Bob Herman, W3IAX

This old thread says to try re calibrating the GPS and the Compass, if neither fix your issue it may be an issue with the antenna.
