Second what DCwom said. For $50 you can get a better paperweight. It has about a zillion nice functions which I always found took about a zillion^2 to access. Hiking was better, but the screen is tiny and takes a lot of toggling to traverse etc. One time I got a lift around a bridge that was out and at the end of the day discovered my maximum speed was 45 mph! One advantage, it uses AA batteries so I could recharge them from a Dynohub, or a solar panel so one could really be independent that way.
