I was searching the WIS and came accross this a while back. Many people have asked me to post it. There is a connector in the new E class meant for a future Bluetooth Module from benz not yet released. The connector is called X39/57 and located in the center console where the phone mounts. There are 2 connectors. 1 has 4 pins with 3 occupied and the other has 20 pins however, 17 pins are occupied. I don't know exactly what they are for but it should be there. I believe the 4 pin is power and the 20 pin is data. Hope this helps you guys.
