Animated turn guidance
Animated arrows represent all route events other than the above-mentioned special points.
These arrows show the direction in which you need to continue your journey.
The active leg of the route
The active leg is the section of the route you are currently driving. If you have not added any
Via points, the whole route will be the active leg. When Via points are present, the active leg
is the part leading from your location to the next via point.
The active section is always the most conspicuous part of the map even when in the
background of a 3D map view.
