it will not serve to lead you, if like me you do not have a great sense of direction, because he does not live GPS! This is a bike computer, which shows you the distance, calories (yeah ... On what basis?) Elevations, but in no way the route you take! Ok, maybe it's me who made a bad choice at the base, but say that in addition Garmin does not help you to use most of this unit, saw the side "gas machine" for their application ! It is possible and easy to get on the computer its route afterwards, but then put it back in the Edge to redo these traces, then there, it is a different story (which I have never found!). Resale .. after two outings by bike ...
