So I installed a new aftermarket head unit and can not get the rear DVD to stay powered on. Goes on, shows the ford logo and shuts off…
I have these 2 connectors (below) from the factory unit and was wondering if.. 1) does the Corp Protocol A and B need to be connected to something and 2) does the rear DVD take a different voltage ie.5 volts and not 12 (side note how is the DVD grounded, is it from the stock head unit?
