Well, this is starting to sound more like something in the way my CIC has been fitted.
Since the CarPlay box won't detect my reverse signal using the can bus and my steering wheel buttons don't work, which should also come via can bus.
I think I need to find some detailed wiring diagrams and pull everything out again and try and work out how my retrofit was done, cause something ain't right...
either that or my carplay box is faulty.
