I have the TomTome Rider 2 GPS which is made for motorcycles. One thing to note is, although it says that it's bluetooth compatable--it only works with a few bluetooth enabled phones. The problem that this poses is, unless your phone works with TomTom's bluetooth, you're not going to be able to use 1/2 of the cool features that it offers. After spending $500.00, I learned that the hard way. My second problem is, the screen is really tiny and while riding, at times difficult seeing where you're going. You can change the screen to different colors but I haven't found the color that will allow me to glance down at the monitor during the day and see where I'm going. Finally, forwhatever reason, the darn thing keeps switching between meters and feet. So at times, you'll hear the announcement, make a right turn in 50 meters.

Otherwise, it's a good unit and has cool features. I like the feature where I can program a set speed. If I go above that speed, I'll get a loud ring in my ear.
