It's a Pioneer AVH-P6800DVD w/AVIC-9DVD add-on navigation unit. I bought the HU in 2007, installed it in 2008, and just this week finally made it down to the paint store to get some paint that matches the original color so I could paint my dash bezel and finish it up. I procrastinate too much! I'm not sure how long it actually took to install, I worked on it anywhere from 30-minutes to a couple hours a day for 2-weeks or so. Pics didn't come out so great (way more bluish than real life), but you get the idea.
Purely coincidentally, the aqua text Pioneer used matches the digital dash color perfectly.

iPod in the center console
iPod fits neatly into one of the cassette slots in the console because it's housed in a modified cassette case.
