Evening all, finally got my install up and working after about 6 months, here are a few pics. The car is a 1990 BMW 318is. It's based on my old PII 400, running off an inverter. I went for a removable screen setup as there isn't much room to mount a screen permanently, and designed my own bracket on CAD.

Software - Runs all these at the same time pretty easily, and boots in around 40 seconds. Much better than I expected.

I have a video of the night vision in action which i'll put up soon, but it's 66MB at the moment and I have dial up

The plan is to add 2x10 IR LED arrays that I have waiting. The IR works great, 30fps, but needs more IR illumination to work well on the car.
***here's the vid:

It's in divX, using latest version of Dr DivX
Right click and save as. It's 40 seconds and 1.7MB.
I will be experimenting more with the IR camera, but it was very strange just driving via the screen

It was absolutely pitch black apart from the screen glow, and it did work. So am I the first person on mp3car to have night vision???! Please say yes
Couple of other things to add soon:
Scroll wheel in console by window buttons
get 848x480 to work properly
get bluetooth dongle to work to give internet connection
Thanks for all the help and advice form this site, I'm sure it would have been another 6 months til it was sorted without seeing everyone elses work. I am now loving my car PC
