When I switched from the B3 to the MS60B, I photographed all the settings of the B3, and hacked them into the MS60 from the photos. Not really efficient, but it sounded pretty much the same
after this procedure.
The USB port on the 60 is for firmware updates only, which kid of sucks. On the other hand, my BMW also has a USB for firmware updates of some kind, but does not accept any MP3 data for
the entertainment system. Which sucks as well.
