An interesting concept that can use some improvement

Author's Rating:

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
