Very nice device, careful construction, easy installation of the sensors and implementation carefree. I know the family of GPS Garmin EDGE and am very satisfied with the party say conventional GPS (navigation, maps etc.) Wifi connections for Garmin Connect and Blue Tooth connections for pairing with my smartphone work well. Mapping "Garmin Round Europe" is well suited to cycling road biking I add Birdseye satellite imagery. I am very satisfied with this product.
