Joe,
I have the Pioneer Z1 - It is a double DIN which means it fills the entire space of the stock radio. I had it in a F250 and moved it over to my SMB after my purchase. Pioneer advertises this as a Navigation system but it does it all. "The next generation of the ultimate in HDD navigation and multimedia is here. Pioneer's AVIC-Z2 is a double-DIN size, all-in-one system equipped with a 30GB hard disk drive (HDD) to deliver information, entertainment, and convenience on the road. Between the Z2's ultra-fast processing and the massive Tele Atlas database offering 12 million points of interest, getting where you need to be has never been so easy. And with a built-in HDD music library, DVD playback on the large 7-inch display, and iPod direct control expansion, the Z2 ensures that you'll be entertained every minute along the way."
The hard drive stores all the maps and points of interest and leaves 10 gig to load your own music -- Every time you play a cd it will burn it to the hard drive and you no longer need the cd -- It burns at a faster rate than the cd so you do not have to listen to the whole album if you do not want.
The head unit come with the Navigation, DVD Player, CD Player. It plays all other formats but will only burn CD's and not MP3's -- I believe it is a copyright thing.
I also have the XM Mobile with NAV Trafiic that gives you real time traffic conditions -- It will route you around traffic - this is a small fee from XM -- $4.00 a month
I have the Ipod controller so I can control any Ipod from the touch screen- It also charges it while it is attached.
Other add ons I have are Bluetooth and Backup Camera (comes on when shifted to reverse and while traving as well)
I also added a Video screen in the rear so the kids can watch DVD -- you can mix any combination -- IE Nav in front DVD in Rear -- DVD on Both -- Music through Speaker while DVD in Rear with headphones.
I am sure I left out alot but here is the link to Pioneer

The only difference between the Z1 and Z2 is updated Maps and software
I bought a Hard Drive on Ebay that made mine a Z2 and to my surprize it was filled with music.
There is a simple trick to let you view the DVD and input an address while driving if are one to live dangerously.
