Hello, I have a Phaeton BJ 04.2012 it is a PDC (3D0 919 283F) address : 76 installed and I would like to install a return camera soon. I would like to know if you can replace the PDC control unit for one e.g.: from the pass, the OPS has (3C8 919 475) address : 10, so that the distance next to RFK is optically displayed. I have already found websites that offer OPS in Phaeton. Shouldn’t you actually go then?Can you simply use a XXX 919 475 STG (umpin + code) or do you have to take notice of something else?
