Can anyone help. I have a factory fitted bluetooth phone kit in my 320D sport touring. Having owned the car for two years, I have yet to be abe to use the bluetooth effectively. The receiving sound quality is great but the transmit quality is very poor. I have to shout (and go hypoxic!) for anyone to hear me. I do not know where the microphone is located either! Any suggestions from anyone would be greatly received or should I give up on it and buy a Parrot!:frown
