thanks! i will do that. thank you for your time and help, i very much appreciate it!Don't know anything about 2008 Challengers and the USB port, but iTunes doesn't normally save music as MP3 files. They are saved as M4A files. If the player in the car is expecting MP3, it will of course say there aren't any.
Open iTunes, click on a song, click on Advanced, then convert to MP3. Save that to your USB and see it it plays.
yeah, they are all downloaded from itunes.did u buy the songs? if so, they will not play on anything else but a apple device. they make there own audio files
