[FONT='Verdana','sans-serif']I started having this problem about three months ago, I have 2003 M3 MK3 Nav 2007.1 and Firmware v29.1, first there is a delay, the GPS is always behind as I drive, the worst is on freeway speed, second it seems like it stops and go, it’s not moving as the car is, third if am driving on the far right lane on the freeway, and I pass an exit, the GPS will show that I took the exit, half a mile later maybe less, it will correct itself and get back. I took the car to the dealer, they put in an extra GPS antenna and put in a new GPS computer “whatever in the trunk” that did not fix it. I am schedule to see BMW rep later on this moth, has anybody seen this before ??[/FONT]
