I know, this seems to have come up on a number of times and i am likely not the first (or last) with this problem, but would really appreciate some up to date help comment. 2013 Evoque Coupe, the 2x Mirror Cameras are fine, but the 2 front one's and the reverse camera are not working, just a blue screen with a camera diagram and a red line through it! I have had the trim off on the tailgate and all camera connections, look clean,dry and fine. This been a 2013 model, it has the very expensive 4 pin, £300 cameras, so i really do not want to pay nearly £1,000 on parts alone, also i have seen people have sometimes bought a new camera only to find it still does not work, so problem must have been elsewhere. All/Any suggestions as to what i can do/try would be really great, whilst i know a bit, i am not too technical so please explain in very simple layman terms please.
