Sorry, missed the thread. I used a jump drive to copy my music, or you can import it from cd. It has to be .mp3 files to my knowledge.
Plug in your jump drive or put in your CD.
On the radio click "My Files"
Then you choose which method you are importing
If from a jump drive, you'll have to check which artist/album/song you want. Best bet is to put your songs on your jump drive onto the root jump drive and have a separate folder for each artist. Inside each artist have a folder for each album, then inside each album have your music files. That's the way I do mine at least.
