My 2008 f150 has CD/Sat. radio. No display, only plays 1 am station, can't change anything. Will not change from AM to FM or CD player or Sat. radio.

 

If your radio has that many issues, I'd just get another oem one off eBay or buy something aftermarket. I did a how to on how to fix the display and can post that if it'll help.

 

Sometimes unplugging the wiring harness on the back of the radio will reset it.

 

Agreed. You can try disconnecting the battery (or unplug the harness) to see if it resets, otherwise I'd find a cheap OEM replacement or go aftermarket with a new stereo. If the cost to go OEM is over $75 or so, I'd just go aftermarket. Much better head units with more watts per channel as well as HD radio/USB inputs/etc on most $120-150 models.
