I did the CIC conversion but have some trouble with the PnP cable so I had to send in my unit. I installed the old CCC unit back but left the new iDrive controller in the center console. I am not able to use the controller so I checked the forum. Nothing really there about new controller on old system.
Does anyone know what I have to do? It is only an USB device so I wonder if there is coding required at all. Any advise would be nice!
