Hi all. Looking for some advice on replacing the rear camera on a 2015 Discovery Sport. Mine has failed with a blank screen and the camera system fail error message. I have sourced a used replacement from a 2017 model which is identical but when I plug it in I get error messages as follows: AEB system failure, lane departure system failure and also camera system failure. I am wondering If I have bought a dud replacement or if the system needs set up or configured with some special software tool? Any advice very much appreciated. Thank you.
