Use the 'Download Maps for Track, Route, or Area' feature to download an offline map that follows your track or route or area. This downloads 5 map tiles (individual images that make up a digital map) on either side of your route or track. Because the tile size is different for different sources, the width of the map may vary slightly depending on the selected map source and the location of the track/route/area.
