A device for ascertaining and displaying a route course for a transportation means comprises a road network. In particular, a navigation device having a data processing device, which is also used to ascertain the route course, and having display means, which are also used to visualize the ascertained route course. The device has at least temporary access to a road network database, and is set up in such a way that upon the existence of a correction of the current direction of the transportation means necessary for following the ascertained route course, which is caused by a transition of the route course from a first road onto a second road, in particular by a road intersection or by a road branch, an automatic change is performed between at least one first and one second operating mode. One of the at least two operating modes causes a visualization of the transition on the display means by at least partial dynamic superposition of at least two visualization layers.
