I have a 2004 Black Sand Pearl Scion xB. Current mods to date include, 7" Xenarc touch screen monitor custom mounted where the radio was. Pioneer 5500MP custom mounted where the storage compartment was.

Custom cold cathodes installed under the dash.

900mhz, 1GB ram, 88GB hard drive space,52x CD-RW, PC under the passenger's seat, running Windows XP, Frodoplayer, Mediaengine, Routis, and Street Atlas 2005. There is also a D-Link Wireless 802.11g network card in the computer for using internet inside of the car. Earthmate USB GPS reciever is mounted to the windshield(behind the rearview). There is also a USB keyboard mounted in the driver's visor. The computer has an OPUS 150 Watt power supply, which turns the computer on when i turn the key to accessory, and shuts the computer down when i turn the car off. It also has a low voltage monitor, so when the battery voltage drops below a certain point, it turns the system off.

Two MTX MXS 1204 12" subs reside in a sealed box in the rear of the car. These are powered by an audiobahn 8000T amp.

Under the passenger seat there is an XBOX modified with an Xecuter3 chip and 120GB hard drive. The xbox contains every Nes, Snes, Genesis, N64, Gameboy, GBA, Game Gear, Master System game, along with over 20 Xbox games on the hard drive, also there are the first two seasons of teh Chappelle show, and the first season of Pimp My Ride, plus the Matrix Trillogy. The Xbox is wired to the computer for playing xbox games online through the wireless network card.

Under the car there is a set of street glow blue underbody neons.

In the rear, where the wiper once lived there is a reverse camera. This is wired to a relay so that when the car is put in reverse the image of whats behind the car shows up on the indash screen.

I also have a touch pad above the monitor to control all the devices(lights, power inverter, camera, etc)

Where the spare tire once lived i have all my wiring stashed...and my amplifier. Including my yellowtop accessory battery and isolation relay.

I installed my Code Alarm 2way LCD security and remote start a few days back.
I Also got the radio hooked up to the alarm so i can turn my radio on and off from the remote (nice for shows, so i dont have to leave my keys in the car) also rewired my radio so it doesn't turn off during crank (becomes VERY annoying) Mounted my MyFi to the right of the lcd screen. I also got my hands on a set of stock 15" alloys ill be putting on soon. Underglows are hooked up to the relays as well.
