2008 X5 and Blackberry Curve problem...
 

My Curve syncs up to the car and when I make a call the call works on the speakers but as soon as the car syncs to my phone it thinks there is an active call and it will not hang up the call even though my phone is not on a call. Because of this the radio or anything else on idrive is not operational. :(

Dealer (salesman) couldn't figure it out today.

Any ideas?
