They also mentionned that I would have to lose my BMW assist during the retrofit, I was also hoping to understand why.
Your car currently has a CIC Navigation, a TCU Assist/Bluetooth module and a MULF-Hi USB module.

To retrofit the Combox you will remove the TCU and the MULF-Hi and install the Combox Telematics in their place. You will need either the wiring diagram and the connectors to create the PnP harness and then code your CIC to enable all the new features on your own or get the full kit from Bimmertech which includes all the parts and the coding.

The transfer of the Assist service from the TCU to the Combox is done by a willing dealer. Meaning, very few dealers are willing to do it.
