What you describe sounds more like the backup camera operation, which has one camera mounted above the rear plate. Also that is D4 which I think was refined/different. The D3 parking camera system (aka proximity camera) is different and has, basically, a surround camera system. Not just one backup camera. It was an incredibly rare option first introduced in 2008 if I recall and not available in the states.. The D4 introduced a much more refined setup. I think basically the D3 system was a "prototype" config they worked on because when the D4 came out the surround camera system was more advertised/pushed to sell to buyers. I dunno. I guess the poster could mean sensors, now that I interchange the text I think either could actually apply.

 

So if you don't have a swing-away spare tire, you are relegated to mall crawling?? I think swing-away spares are stupid, and I'd put my right foot up against anyone's off-road.

I think the last few posts were made to help understand the problem, not to split hairs.
