After initial problems (a GPS novice) with the unit I am very happy with the Garmin. However, first missing maps. You have to be downloaded only from the internet and play on an additional micro SD card. Although the device can also be used without a card, however, takes a lot of imagination to determine unequivocally a prefabricated track at an intersection. However, the Edge 800 has become all my expectations. It distinguishes driven tours, shows me important data. But with caution are the routes that are displayed on maps as OpenStreetMaps or Google Maps. Some forest roads turned out to be more than boar wallowing because as paths. Most often this is related to outdated maps. Nevertheless, for the money in connection with a 8GB micro SD card and Open Source Map a great GPS device for biking!
