I want to know if there is a way to integrate a cell phone into an M3. my friend used o have a MBenz and he had this feature where he could simply plug in his cell under the middle armrest and when people would call, radio would turn down and he could hear them through the speakers and talked into a micro placed somewhere. I've never heard of this feature on an M3, but is it possible to do? does anyone make any product that allows for this to happen? driving a stick and talking is hard. Thanks for all your help
