What type of connection does the factory backup camera have? I'm assuming it's not a universal rca. I just bought a 9980dnx and it came with a cmos 300. I was wondering if anyone had been able to daisy chain the factory backup camera or if there is an adapter to hook it up to the kenwood h/u. I was thinking about putting the cmos up front and have the factory in the rear. Anyone have any ideas? I've been having trouble finding out the answer. Thanks!
