I have a droid Razr and a BMW e90 2006 325i. I can successfully pair my droid razr to my bmw. I can also send calls to people but when someone try's to call me and I accept the call my radio comes back on and I can't hear the person who called me. I noticed the bluetooth button is active when I send a call out. But when i receive a call on my phone the bluetooth button on the bottom left hand corner next to the mute button is no active... Sorry this problem is kind of hard to explain. Thank you for any help. I know its a problem with the phone and not the car.
