I have a 5th gen ipod nano which has given me years of good service. In the last few weeks when I have come to sync it with my itunes library on my imac when the device appears in the itunes sidebar clicking on it no longer brings up the summary page as previously. Instead I just get a message saying that there isn't enough room on the ipod to sync but as I can't get to the summary, I can't see what is on there or how to delete stuff I don't need. Anyone got any ideas????
