06 FX4, stock radio. I've had it a few months, and no recent dash work as far as I know. Strangely enough, the radio is now working fine. But before it went back to normal, it would be on the fritz when the motion of the truck would change, like coming to a stop, taking off and going over bumps. It makes me think that it's probably something that has a so-so connection so sometimes it will break that circuit. It doesn't seem like it would be a short to ground because I'm pretty sure if it was, I'd have a blown fuse and it wouldn't work at all. So IF it is a continuity issue, it's probably most likely a short to power. Anyone got the wiring diagram for the radio circuit?
