 _Tracks_ does not contain a _map_ (as this would required Internet access).
 To show your tracks on a map, a 3rd party application (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand) or [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro)) needs to be installed.
