I have a D3 that came with the Ipod cable. The other day a friend of my wife's gave us a 4gig Nano. It plays the music fine. But when a song ends and it goes to the next song, the song's info (song name, artist, etc.) on the screen does not update. It will update the info on the screen if you manually advance to the next song by hitting the skip button on the screen but not if left to advance on it's own.

Any ideas?

If you know anyone else with an ipod, see if they'll let you hook it up to your D3 and see if it does the same thing.
