Pyle makes one that includes the backup camera display + bluetooth and is around 100 bucks. there are other manufacturers that make them with bluetooth and NAV. And it's not really $500 that was just one vendor I found the same model I was looking at before for $200 less i just didn't do enough searching. the Rydeen model is pretty slick

And I think cool gadgets like that are perfect for the VX. I get more heads turning on my VX than any escalade.
I may even think about this one and take out my garmin.
