Re: Zumo 660 or Zumo 550
I have a question for you guys that have the 660. Can you play MP3's via the internal speaker when the unit is on Battery power. On the 550 you can only play music, audio books and such when the unit is in a powered mount. It would be nice from time to time to be able to carry the unit into a motel room and use its playback.
