IMEI number is the number you are looking at in your telematics combox to match with your existed TCU number.
Combox communicates via MOST. Can bus is needed for something else, but not for the primary communication.
You may get canbus from different modules depend on the vehicle. I would suggest to look in to WDS (we have one for free at our bmwretrofit.com) website and find where is the easiet and nearest palce to get CAN from
Nearest places to get CAN for combox on E9x series - right wiring harness. Fast connectors will help
