O title should sau back up camera picked up a pioneer double dinn and bsck up light. It is activated by reverse. But if you leave the setting turned on you get annoying ms saying image might be upside down. So I am woundering if I wired it to the pioneer constant power and just turned it off and on when I wanted if I wold have any problems. Same thing with movies. Can only watch in park. There had to be a way to close that circuit without buying shit on eBay. Thanks in. advanced One more question. It had an av in and am av out port as well. Could I put second camera in av in. If not do they make a switch where I could mount multiple cameras and switch the view with switch. Thanks.
