I have an '08 X5 and a BB 8300 for ATT. When the phone syncs with the BMW it seems to sometimes lock up the phone. I am able to control it through iDrive, but once I get out of the car I am unable to get any buttons to work on the phone. I either have to wait a period of time or undo the battery to reset the phone.

Anybody else have this problem? Any solutions?
