hey.. just bought a waterproof colour camera from ebay... wanna connect it up to my in-dash dvd player. dont really know about cars, but got a hole a little to the right of my back numberplate, that has a removable cap on. Would it be a gud idea to fit the camera there?

Also, how would i get the cables inside the car, so i could connect to head unit..

Thanks!
