AUX Jack.. dude ya, use that... man, no reason for FM if your radio has one. $5 cable and you are set.
You need an iphone one... the common mini jack won't cut it.. but they have them at walmart.haha i never bothered trying to find a cord for it. Didn't know if it would work or not.
If you "accidentally" broke it while beating it in anger, I'd hate to see what you do to things on purpose, lol...
