I am considering purchasing GPS for my bike. I was wondering if it is really necessary to get one specifically made for a motorcycle, or will one made for a car hold up okay on my bike? If anyone has any input on specific models they have tried please let me know. I am only looking to spend between $200 and $250. Right now I am looking at the Garmin nuvi 360 Portable GPS with Bluetooth if any one has any experience with that particular one.
