i have a 2012 ford f150 with the factory amplifier. i have all the wires connected, canbus box, etc. steering wheel controls work, i can turn the volume slider up/down, but i don't hear any audio. are there any vehicle specific instructions for the 2012 f150 to get sound to work?
i previously had a cheap android head unit and the audio worked correctly with no modifications needed to the vehicle wiring.
