OK here are some installation pics...
The headunit as you can see from the first pic is the Kenwood Excelon DNX 8120

The rearview camera is the Kenwood CCD-2000
I had to make a template out of some spare plastic hat I had in order to provide a stable mounting point underneath the rear bumper.
I chose the right side of the license plate to mount it, but I think you can mount it anywhere you want really.
Wiring everything up was fairly straightforward. I provided a few images of the screens... Grounding the parking brake wire works fine and allows you to utilize all the functions of the unit even when you're moving. DVD movies play flawlessly. The unit even comes with 2 additional a/v inputs so you can run a PS2 (or 3?) off of it. It has one additional video out and although I don't have an ipod, it can connect via a USB connection. Also, you can use a second USB port for a flash drive - pictures, movies, songs, whatever. I found that the ideal angle for the screen (given the fairly bright glare from the CA sun) is at -1. If you have tint, you may be able to get away with the 0 angle (pictured with the unit off).
The bluetooth is great and automatically picks up my Centro without problems. I mounted the microphone on the driver's side A Pillar. From tests so far, the quality is great.
Still figuring out a few things, but so far very happy with this purchase. I was able to get in on a preorder, so I got a pretty awesome price for it.
I'm not quite familiar with flickr but here goes also:
