Hi,
I have read the two great posts about the surround view retrofit on F30s (3-series), but I have a 2018 430i Gran Coupe that I have collected a bunch of parts to begin the surround view retrofit, and I realize there are minor differences. I am wondering if anybody has done the retrofit on the 4-series? Specifically, when I look at the normal and repair parts list, I can't find the HSD cables that should run from the mirror cameras to somewhere. Since I haven't begun the disassembly process, I don't know if the existing door wiring harness already has the unused video connector in the door, or if I will have to get a custom cable made to run to the camera ECU or the connector near the bottom of the A-pillar. Thanks!
