Dear All

First, thanks for a great forum but now I really need some help and I hope someone has the golden answer :-)

My car is a E61 from 2008, born with M-ASK, Bluetooth telephone and CD changer

I have recently bought a CCC unit with the 8" CID. The unit was coded to my VIN and also bluetooth and CD changer.

I retrofit it to my car, almost just plug and play, only the wire harness for the fan was made.

The unit works perfekt, but my bluetooth and CD changer does not show up.

My phone recently connected to the car with the M-ASK system, still connect perfect but I am not able to hear or control my phone from the CCC unit

What could be wrong? what should I do?
