I have the TOMTOM GO 700 on my bike. Here is my thoughts of it. The screan is not bright enough and the audio can not be interigated into the bike audio system. I had to modify the mounting system to go on the bike. Other then that it isn't to bad a GPS. I would ge something else if I was to get something just for the bike again. Maybr the TOMTOM 910 or a Garmin Unit.
