The Garmin Edge 520 Plus is the updated version the Garmin Edge 520 that was released in 2015. The 520 Plus has an advanced GPS navigation system as compared to the Edge 520. The Plus comes preloaded with Strava Live Segments and the Garmin cycle map with turn-by-turn directions. The Edge 520 is great for training but not navigation. It does not have cycling-specific maps, and does not have turn by turn directions. It only has breadcrumb type navigation.
