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.
Thanks, that clears a few things up for me. The wiring diagram seems to be in the combox installation pdf, unless it is missing something in there that you know and I don't.

Can you clarify the SA 606 without SA 6FL & SA 609 without SA6FL? ( I'm assuming that SA6FL) is the bluetooth interface/adapter or the combox name?

thanks for helping out, I really appreciate it.
