I have never found navigation on edge units reliable. I am now using an Edge 1030+ after previously used an 800 and 1000. None of these units were usable for navigation to a location. On Monday I tried to make a journey from Emosson in Switzerland to Chamonix in France. This is about 30 km along a single road with no sensible options. The Edge proposed a 169 km route heading into Switzerland in the opposite direction. Fortunately I knew where I needed to go and the road signs were good. Even entering the outskirts of Chamonix the Edge tried to direct me up a mountain along gravel tracks. The routing is set to road cycling. Is there any improvement in the settings or can the edge not be trusted for navigation?
