Hello Clio Friends After I have installed my wife a rear-view camera it no longer turns on and off…manually works by a button but is not meaning of the thing…after having measured everything with a colleague we noticed that there is no longer a permplus there on the plug of the radio…presumably it loves that it doesn’t turn on and off anymore…securings all controlled and seems to be all right….someone might have a clue what it might be about that’s gone all of a sudden! Thank you all!
