The nuvi 350 boes on road, off road, pedestrian, and much more. I have been told though that it is not good to get dirt between the screen and housing. But all around I have had great luck with it. And it is a little bigger than a deck of cards with a small flip up atena on the back. Some of the navigation gpsrs are a little bulky. The only complaint that I have about it is that there is no good way to stow it once you get down to the location. Yes it does have a leather pouch but that is it.
