Has anyone seen or looked into the Pioneer ND-BC20PA, rear view camera with parking assist? I know it is pricey, but reviews say it is best on market. I found retail price is 439.00, but have found them in the 286.00 range.

Nice looking featureset but that camera is pretty big, and it's expensive.  It might be worth it if you have a place to mount it that's not terribly obtrusive.  I installed a small Boyo camera and while it's not perfect it has the advantage of being completely invisible up under my trunk lip and gives me sufficient visual capability to get within an inch of the bumper without hitting anything behind me when parking.

$294 on Amazon

Still debating with myself

I have a truck with aftermarket black bumper, and looks like it will mount pretty inconspicuous.

What does it do that a regular camera combined with the head unit don't already provide? Reading the comments seems like all it does is give you parking lines. The NEX has this.

I'd save your cash either way. Buy a camera and also buy/install this http://m.ebay.com/itm/121199838063?nav=SEARCH

I went with a less expensive camera, and it works great. figured i could use the 200 dollars saved on something else. Camera is installed and works great, I just use the lines on the camera.
