Hope someone can help me here. I've got a RAV4 Cruiser on order and due later this month. I want to put a reversing camera on, but just can't bring myself to spend the outrageous money that Toyota wants for a genuine unit. So a couple of questions. 1/. Does the Display audio unit have an RCA input for a reversing camera so it can just be plugged straight into the rear of the unit 2/. What is the video system on the Toyota unit - PAL or NTSC - or auto switching, so I can order one from HK 3/. The guide lines are camera specific ?? - as in depends on the camera 4/. Don't suppose someone can measure the cutout in the licence plate light for me, to make sure I get the right size, as they all reckon the unit just clicks into the space where one of the lights were. Thanks in anticipation.
