Sleeker than the TomTom Rider

Measuring 4.8 inches wide, 3.9 inches high, and 1.6 inches deep and weighing 10.6 ounces, the Garmin Zumo 550 is sleeker and sexier than the TomTom Rider. The unit also has removable caps on the top and bottom of the unit, so you can swap it out with snazzier designs.
