After reading lots of reviews, I decided to put my money down on the Garmin Zumo 550 instead of the Tom Tom Rider. I'm sure I'd be happy with either, but I went with the Zumo because of the universal praise and the fact that I've already got a Garmin C330 in the car. It comes with 2 types of Ram-mounts depending on bar type, and the install was easy. Now if it was just a bit warmer I could give you a real world test
(In addition to the bluetooth, MP3 player, etc, I like the little motorcycle icon on the screen instead of the generic direction arrow or car)
