The Navigator even goes one step further, as it not only displays the track on the map, but also converts it into a navigable route. This has the great advantage that you receive navigation instructions with arrows and audio.
If you deviate from the specified track, the routing will first take you back to the place where you left the track. As soon as there is a shorter route back to the planned track in your direction of travel, you will be guided in the direction of the track.
If you have planned your track with an external planning tool and the track is defined using waypoints and/or "shaping points", waypoints are always travelled to as fixed destinations until you skip them. "Shaping points" are only used for the route.
