2007 F-150 Updraged Nav system not working
Battery died in truck. After charging battery, Display and radio will not turn on. Have changed fuses and still nothing. It appears to still have power because there is a glow to the screen when truck is on vs when not on. What am I missing?

I did read this from another thread, and we haven’t tried this yet.....so maybe....
”You may have to remove the stereo and unhook the wiring harness. Is it the factory stereo? It may have a fuse on the rear of the stereo that might have blown, but in each case it has to be removed to check it. If there is no code info in your owners manual I doubt the factory radio is code protected. I could be wrong, I have not seen a factory 04-08 head unit in some time. Long story short pull it, disconnect it, check for fuse, try to press and hold the power button if it has one.”
