I am having an issue with my Nav in my 2006 Commander Limited and I am hoping someone may have seen this before. When on the map screen, the location of my car will not update. It shows that I am not moving, but will rotate my direction of travel. I went into the emergency information screen and checked the Longitude/Latitude numbers with google maps and my position is correct and updates continuously (7 Satellites). I have removed and reinstalled the CD and I have disconnected the battery and turned the ignition to "On" as a hard reset. Any other ideas would be much appreciated. Thanks!
