you shold actually look int he classifieds on here. If I were you I would look for one from a 2005 or 2006 F-150. Reason is because apparently some of the 04's had defective MP3 players on them (the audiophile 6 disc changer).
I bought one from ebay from a 2004 specifically for the reason of wanting to it to play mp3's. When i got it, it wouldnt play and said "bad disc" and spit it out. Even when I burn a disc but not in the mp3 format, it will half ass play, and skip around and then eventually quit playing and say bad disc. afterwards i did a look up, and i found where there was a recall or something like that on the 04's. i got burned, so be careful.
