I had reverse camera view on my Kenwood DNX516 without engaging reverse on my last T6., even while driving - the Kenwood and camera were fitted by a Lookers van centre. I refitted the Kenwood and camera to my current van and the local auto sparkie said that it couldn't be done when I asked for the same functionality. As it was a battle getting it installed normally I didn't push it. It's a good option for discreetly viewing what's happening behind the van when you're parked up without being obvious about it.
