Hello all :)
I'm thinking to add aftermarket backup camera to my volvo. My volvo is equiped with nav screen but without backup camera.
In screen there is a socket to connect backup/front cameras. It's easy to connect and find right cables.

But one thing is that I need somehow detect that car is in R and switch video source of the screen.
I'm thinking to build it with arduino. Maybe there are some info about volvo canbus?
