This setup does everything with one box. I did add a HAM radio faceplate that sits just in front of the shifter where the "How to shift into 4WD" sticker is. Compared to most trucks that have GPS, FM Radio, CD Player, MP3 player (iPod), and XM/Sirius, I think it is significantly cleaner to have all of the controls combined into one touchscreen.
For software I ran:
Windows XP Embedded Custom OS Image
Road Runner carputer software w/ a custom skin
Overland Navigator Touchscreen GPS Mapping Software
It combines the following functions in one single in-dash unit:
MP3 Jukebox
GPS Navigation
CD Player
DVD Movie Player
DivX Movie Player
XM or Sirius Radio
FM Radio
Hardware was:
Xenarc 7" Ultrabrite touchscreen
Custom Case that bolted to Land Rover factory CD Changer bracket
Epia Mini-ITX motherboard
1 gb RAM
80gb Laptop HD w/ antivibration mount
Slot-load CD/DVD drive
USB to IDE converter to allow me to run a long USB cable to the remotely mounted CD/DVD drive
Mighty GPS SIRF III USB GPS w/ through hull mounting design
