I went from a no idrive set up to installing the double scoop dashboard, retrofit the CIC unit and Combox with 6FL and Bluetooth.
I got fellow forum member alpina527 to do all the coding and took a lot advise from asfar, voucher76 and booster4075. The latter forum members have done two great write ups which I used to complete the install.
