Hi all, I'm new to this forum; I recently got a D3 and a problem came up with my new ipod nano (latest gen, the touch version). Anytime I plug it in either in audio or video mode, it plays for about 10-15 seconds and then the music shuts off. I need to unplug it, reconnect and it all repeats. The ipod works fine with other docks. I wonder if anyone ever had a similar problem? Am I missing something in the setup? Any comments would be much appreciated. Thanks!
