if you have a PS2 you don't need a DVD player also. I want to do something also but I have to figure out a set up that will work and not take up all kinds of space.

if you want to put a ps2 in your ride you can put it under the center console cuz there is a big spot under the radio where u can set a ps2 but u still would need an inverter for power.

If you have a hitch on your car .. buy one of those back up camras for people with trailors and mount it and wire it into the monitor with a switch.. this is legal my friend has it in his lincoln and he got pulled over and questioned about it and he said just that.. that it is for towing.. Its a good idea and it is proven to work..
