So I have an old 160gb ipod that I figure I'll just keep in my new Challenger since I don't really use it anymore. Can I just keep it connected via the usb connection? It seems like it doesn't recognize it unless I unplug it and plug it back in. Also, when I do get it connected and choose browse, it just stays at the "please wait" screen. How long does it take to load a the ipod library?
