This afternoon my car was at a BMW specialty chop with a water pump problem. When I went to pickup the car this evening as soon as I started it I noticed the NAV coordinates where all over the map. The car would not even show the name of the street on the side screen. I searched the forum and read many similar problems but no one mentioned the cause of the problem or a definite fix. Some people took their cars to a parking lot and went in circles and fixed the problem for few days then came back.

Is there anyone out there that had this problem and found the cause and fix it for good? Thanks

 

Anyone!
