I've read plenty of posts saying that you need to run an additional wire to the reversing light (via a relay) to force the HU to switch the the reverse camera when reversing, but cant find any specifics. i even email toysinyourcar a week ago as they sell the lead with av in, av out and reverse camera in, but no reply.

Does anyone know which pin on the blue plug i need to tap into, and what signal it needs?

and also if anyone knows the pins on the white plug to wire the reverse camera into (as i currently have the av in lead but it doesn't have the reverse camera input).

Cheers
