Select a destination and Edge 800 provides turn-by-turn navigation prompts on screen. Edge 800 can also guide you along routes you or other cyclists record on sites like RideWithGPS, which this site uses.Any activities you upload to your Edge 800 are stored as courses. You can also use BaseCamp to create a route, view elevation changes and other data, and then upload to Edge.
