I use a Droid for mine now. Flawless stereo bluetooth, great mapping with Google Maps, excellent music apps and a bunch of other extremely useful apps. I sold my Zumo since I never used it. I did pick up a good case for the Droid and I mounted it to my tank bag rather than bars, but I like that since it is closer and detaches with the tank bag. Garmin and the like days are numbered IMO. Inferior in almost every regard these days. It won't be long before rugged versions of these phones come out if you want to wait.
