| If you don't have any other devices on the fibre ring than the CDC, then the fibre ring should not be a problem (if you can abandon the changer or put an iPod interface instead).
But it would need CAN-bus signals still. I don't know if the CAN bus from a D2B car would be compatible with that of a MOST base car, it could but I'd suggest you to ask from some of the retrofit experts. |
