Guys
Something I thought you guys might be interested in. This guy is on MP3car.com and has come up with a way to get information from a cheap Ebay reverse sensor kit to display on his carputer along with image from his reverse camera.
He has also done the same with a cheap Tyre pressure monitor system as well - giving an audible (and visual) alert if any of the tyres need the drivers attention.

You can find the related threads on MP3car.com easy enough so I havent linked them
I hope this helps some one - its all a little to complex for me (as much as I'd love to have these things - im just not smart enough)
