anne,
I am in the same boat as you. I am older & have no knowledge of these devices ! I did find that if you go to SETTINGS from the main menu, then choose SYSTEM SETTINGS, scroll down to USB MODE and Click on that and it will show three ‘modes’. However, Im not sure when to use them or not !! I set it at MSC but right now Im ready to send this back and get an IPOD which everyone tells me I shouldve gotten to begin with !!! I have some albums on my FUZE but they are sounding like a skipping record …who knows why !
