Since my last post I took the car into the dealer and they updated the software, but this did not fix the problem. I emailed BMW and they suggested that I check with NAVTECH. I emailed NAVTECH and they suggested it was a hardware problem and I need to go back to the dealer. Something that I didn't think of in my last post was to mention that I think that the GPS is using the Sirius Satellite Radio antenna. That's all that's on top of my car; there is no typical "air hockey paddle" that you see on the cars with NAV systems but no SatRadio. I'll update this after I go back to the dealer. Anyone else have this problem?
