Since yesterday my camera image has failed. No camera setting works anymore. Both in reverse, GPS as well as the manual key function. If I press the key function below the central monitor, the light of the surrounding ambilight strip will go out briefly. Had used the trailer coupling shortly before and then drove in again. Then much to me that the cameras will not bring any more picture. I have now put the vehicle in the garage and locked it. Let’s see if what b Has anyone ever had such a malfunction?
