hi everyone, i was sent here from a bmw forum. They said you guys have the best knowledge on navigation sytems.. I have navigation in my 2001 m3, im not sure what model (mkII, etc... ) however the navigation is not working properly, it is not getting any satelite signals and can not update the almanac. i went into sensors and it says gps malfunction. does this mean i have a bad gps antenna, how can i fix this problem.. thank you
