I'm new so here goes. I have a 2005 z4. I have had my z for 2 years and JUST found out it had bluetooth. My iphone 5 paired with the car just fine. All my contacts are in and I can make and receive calls. It rings in the car and the radio goes off. Now the problem, there is NO sound. I can not rear the caller and the caller can not hear me. I took it to BMW and they could not fix it. Can anyone help?

P.S. I did turn the volume up.
