I created a "trek" route (On OS maps, and imported into Basecamp - copied to Etrex.\nWhen trying to follow the route the map is not visiible, only a white screen shows.\n\nTo resolve I had to:\na. delete ALL nearby routes\nb. Delete All nearby Waypoints. \n\nOnly after this did the map show.\n\nSo, I have no chance to see a route over laying the map. \n\nMaps are paid for high detail ones. (UK local sections).\n\nQuestion; Is there something else to do to have off road routes visible together with a map?\nIts not much use without the map.
