OEM Nav head unit help PLEASE
What causes my nav unit to show the wrong location? When I hit my map button, everything comes up fine, but when I start driving I notice that the position marker is off by at least 3/4 mile from where I actually am. Every time I make a turn, the map rotates but it doesn't scroll to keep up with my current location. Sometimes I drive almost a mile before the map updates location. Is there something wrong with the unit or the map dvd? Can the issue be corrected by the dealer by programing? Anybody!
