On older trucks, we always disconnect battery for a bit and then reconnect, forcing a reboot of all the electronics in the truck any time we get goofy crap like that. I'll defer to anyone with your model year. Just throwing that out there. It's kinda like always rebooting a PC before contacting the Help Desk.

Sirius is a separate unit in the rear electronics bay, as is the Navigation unit, so there is a separate AM/FM receiver unit somewhere, don't remember if its in the head unit, or also back in the rear electronics bay. each has its own fuse, so check for a blown radio fuse.

It came on twice but off again. I am willing to bet it's in the **** head unit, so what $1000 then? I'll deal without a radio. Ill try hard reset later

I had mine do that a couple of times maybe three years ago, turned out it was just a wonky connection at the fuse panel. I think a little bit of corrosion or something else built up on the blade of the fuse to the radio (or amplifier), and while it wasn't blown it either delayed the radio from getting power long enough or there wasn't enough voltage getting thru the fuse that the amplifier ignored it. The next time I started the car it worked fine and it did it randomly for about a week. I Pulled the fuse out and replugged it in a couple of times and it hasn't happened since. The electronics in the truck expect things to occur in a certain order and if they don't the computers ignore them, or still produce error codes even though the item is functioning fine.

The Radio module is a separate unit in the left rear electronics bay, so if the Serius unit works, at worst it would be the unit in the rear, not the head unit in the dash.

It has what appears to be a Ford Part number on the label AH-42-18C15-AH.

On the 2010-12 MY L322 the AM/FM receiver module is directly behind the lower glovebox, above the footwell trim which will need to be removed to gain access.
