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.

All maps are preloaded on the Zumo 550's hard drive, but there is an SD expansion slot on the bottom of the unit if you want to carry music files on an SD card.

Garmin packages the Zumo 550 with a motorcycle mount and includes the tools needed to mount the Zumo to a bike's handlebars.

We had no problems installing the mount onto our 1998 Honda Magna VF750, and the cradle held the Zumo snug as a bug.

We also appreciated the fact that Garmin threw in a vehicle mount, an accessory that was not included with the TomTom Rider.

If you're using the dashboard mount, make sure you get the placement right because once you peel off the adhesive, it's not going anywhere. Bonus: the car mount has an integrated speaker.

The Garmin Zumo 550 has a healthy points of interest database, but we found some of the entries to be outdated.

There is also a handy trip information page that displays your direction, speed, maximum speed, and a fuel gauge. The last feature will only show when the unit is connected to the motorcycle mount, however.

Unfortunately, the compass only works if you're in Off-road mode. Otherwise, the Zumo simply tells you on the map-view screen which direction you are traveling in.

Once your phone is connected, your phone book should be synced to the Zumo. However, we had some difficulties getting our Treo 650's address book to sync with the Zumo.

Here is the onscreen dialpad.

Once on a call, there is a phone icon that pops up on the map menu; touch it, and a menu pops up with a huge End Call icon.
