wait
in this broken (?) old touchscreen lcd car stereo, there's a yellow rca on the back labeled "cam in"
this implies that (at least some) backup cameras are just sending tv signals to the head unit, which knows when the car is in reverse (because of the purple-white wire) and then outputs whatever it gets from that rca
meaning that there's a decent chance for being able to do all sorts of things to the incoming backup camera signal. including cast it to my phone..?
