Good afternoon. Last night while going home I just happened to glance at the compass reading and it had me traveling NW when in fact I was going NE. I turned on the nav system to look at the map and it showed names of streets several miles from where I actually was and had me driving across a lake. I deleted all of the recent locations I have searched on for driving directions thinking maybe something was still active but that didn't change anything. I stopped and did some shopping for maybe 1/2 hour and when I left the parking lot everything was still wrong. Then, all of a sudden I noticed that the compass reading made a couple changes and then corrected itself along with the map. This morning while driving to work everything was fine. Anybody ever experienced anything close to this???? Thanks......Don
