Yes, I use a 1st Generation iPod Nano 4GB through the USB jack without any problems. I also have a 5th generation model that I haven't tried, but can sure test if you'd like. I assume you're having problems. What model are you using?Wanted to know if anybody on the CT forum is using an iPod nano in there CT. If so is it working OK. Do you get the CT with a cable to connect to the iPod?
Edit: I have NAV if that matters.
