Anyone know where the reverse signal wire in Cayenne is found?
Not happy with the stock head unit, I replaced it with a much improved aftermarket variant. All wires accounted for except one, the reverse signal wire, otherwise everything is perfect. Without the reverse signal wire connected my reverse camera won't come on automatically (needs to be selected through menu as opposed to just popping on when reverse gear is selected). Where can I find this last troublesome wire to tap into so the new head unit is 100%.
BTW: Cayenne is '09 model if that makes any difference (I woulnt'd have thought so).
