hi, I'm looking at my friends iPod Nano 2nd gen 2g. I cannot get it to come up in iTunes on my mac. It won't turn on when its in my hand or when it's hooked up to the mac. However, if you mess around enough it will work on an iDock to play one song but i couldn't change the song. I have tried to reset it several times. Any luck about what it might be? I don't think that it was abused or physically damaged. It does turn on though. Any help? Thanks.
