Thread: Needing A little upgrade to Carputer

I need a little help with my setup. First here are the specs of everything.

2004 Dodge Ram 1500 Quad Cab 5.7L Hemi 4x4

Stereo-
Pioneer DVD/CD/MP3 Head Unit DVH-P5000MP
Pioneer GEX-P910XM XM Tuner
Lilliput 7" Touchscreen with 2 LCD Headrest monitors
Rockford Fosgate Power T15004 375W amplifier
Rockford Fosgate Power T30001bd 3000Wamplifier
4 - Rockford Fosgate T115D2 Power Stage 1 15" dual 2-ohm subwoofer

Computer-
Motherboard: ASUS A7N8X Deluxe
CPU: Athlon XP 3200 Barton 400 FSB
RAM: 1GB PC4000 DDR
Video Card: ATI Radeon 9800 Pro 256MB
CD-Rom: 8X External DVD-RW Drive
Hard Drive: 1 Terabyte (1000GB) 5 Hard Drives
Power Supply: Antec True Control 550Watt

Power Situation:
2 - 160Amp Alternators
3 - Optima Yellow Top Deep Cycle Batteries
1 - 1000watt inverter
From inverter to a Tripplite 800 watt battery backup connected straight to the computer.

Here is the situation....

I am doing a custom in-dash install with the Lilliput Touchscreen that will connect to the computer and the DVD Head Unit. I have built a custom computer case for underneath the front seat. I have a Directv receiver installed going to the computer.

First... I need a cheap solution to add GPS to the computer that will display on the touchscreen.

Second... I want to add 8 cameras to the truck for 360-degree view. It needs to go through the computer, so I guess I need some kind of capture card, but needs to accept 8 cameras. I am also needing software the will display the video, possibly like a quad screen effect and possibly record video.

Third… I need software to record video from a TV Tuner Card for Directv.

What I need:

GPS receiver / Antenna / Software
8 Color Cameras / Capture Card(s) / Software with quad screen and DVR
Software to record video from Directv from TV Tuner Card

Thanks,
