Hiking enthusiast I decided to let myself be tempted by a dedicated GPS has this activity. So it's logical that I headed towards one of the "precursors" in this area: GARMIN 1st big disappointment ignition: No card installed inside !!! And you can try to find this info in the product description, it is not marked anywhere !! And when you see the price of the cards, see our GPS doubling its price, it's getting expensive !! Another disappointment size screen but really just too small on this model. Difficult to move with the paper map remain indispensable. Finally, after finding a card dedicated to GPS (GARMIN cards sold on the site), I went to an awful lot of information has not listed above including: the little paths, slices etc .... a drama for hiking lovers in the forest like me !! Finally, I find its use very complicated and not at all intuitive .. I might be the attempt a GPS a little more upscale. In short, too many things that make me regret my purchase. I use today primarily as computer time and leg lengths ... and not at all to guide me.
