A leap in function

Pros: For motorcycles, but also great for car and handheld usage; Works for geocaching

Cons: No Mac OS X support yet; Routing sometimes takes you onto very secondary roads

Bottom Line:
The best GPS I ever had, don't be fooled into thinking it's just for motorcycles, or just for navigation. Read More

Outstanding GPS for a motorcyclist

Pros: Easy to see and use.

Cons: User manual is not extensive enough.

An interesting concept that can use some improvement

Pros: Small, Powerful, Bright display, 4+ hour battery operation. Very sensitive. Car & Bike mounts included.

Cons: Fuzzy display graphics. Poor TTS quality. Not configurable.

Bottom Line:
I still recommend the 276c over this model for the knowledgeable motorcyclist. The 550 will be better when they resolve some of the flaws. Maybe the 450? Read More

One satellite short of a full constellation.

Pros: Rugged construction, bright display, good support, large POI database.

Cons: No audio while on battery, limited control over route legs.

Bottom Line:
Definitely a must have for motorcyclists needing a GPS.  You can't go wrong with the Garmin name brand; they stand by their products and the support is excellent. Read More
