Claim One:
1. A device for ascertaining and displaying a route course, comprised by a roadway network, for a transportation means, in particular a navigation device, having a data processing device, which is also used for ascertaining the route course, and having display means, which are also used to visualize the ascertained route course, and the device having at least temporary access to a road network database, in which the device 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 causing a visualization of the transition on the display means by at least partial dynamic superposition of at least two visualization layers.
