Professional CD (non I-Drive)
Under "Audio", select "CDC" (cd changer)
This screen will look exactly the same as if you had a cd in the cd changer. You can set up playlists, using your radio preset buttons here. Select "List" to take you to your typical iPod menu.
Once you have selected "list" you will see your standard iPod menu, showing "Artist/playlist/albums/podcasts etc etc". I selected "Artist"
Once you are in the "Artist" menu, you can browse using the right knob on your stereo, just like you would with an iPod.
Select an artist to listen to.
Select a song to listen to.
