I haven't looked into a car with idrive, but you may just need a TCU + programming. I have seen mixed schematics and such, but you may need a seperate microphone for the bluetooth. The FZD I pulled from a salvaged 330ci w/ idrive had 2 mics. You probably have the loudspeaker already so upgrading to bluetooth shouldnt cost you more than the TCU + programming (5-600 bucks). programming with CCC takes longer unfortunately. My car was prewired for bluetooth....search the forums for the necessary pdfs that are required for this retrofit, you should be able to find all the info you need. I found a TCU on ebay so i didnt have to get it reprogrammed. If yoy get one off ebay, you will not be able to you your assist properly without dealer program.
