so when you put back the OEM radio, the reception was fine?
Customer: replied 3 years ago.

yes it was fine, i have looked at loads of threads on this subject, some say it is the diversity antenna not getting the right amount of voltage or non at all and you need to connect the blue/white antenna power lead from the new head unit to a white wire in the BMW radio wiring harness, but there is no white wire on mine?
