What you would need to do is, EITHER Join all the cameras into a single feed on the composite line, and connect it to the Lilli. Then, Just power the individual cameras from the reverse lights or the left or right turn signal, depending on where it is.
You could also look into Composite Video switches. I did a quick look, and found many, but I am not sure if any/how many can be controller electrically. Some have remotes, and the remote can be hacked so that it automatically chooses the proper signal, so you don't have to hack all the cables together.
Another option is to use a USB relay controller, that can control either the composite switch, based on which wire gets power (Left, Right,turn signal and reverse wire).
There are many ways to do it, just got to think out of the box.
...I love the French language...especially to curse with...Nom de Dieu de putain de bordel de merde de saloperies de connards d'enculés de ta mère. You see, it's like wiping your *** with silk, I love it.
decided im gonna get another 3 smaller lcd screens for each camera plus my usual one for the carputer.
then find a way to make them all look stock so my car doesnt get nicked in 10 mins flat
