Abstract
Comfortable navigation is made possible with a small amount of transmitted information by a terminal unit, a central station and a process for the transmission of route information completely defining a route of a vehicle in a traffic network, which route is suggested as a navigation aid, from a central traffic station to a terminal unit in the vehicle. The route information concerns path points located on the suggested route, wherein a path point is defined wherever it is recommended by the central traffic station that the vehicle turn off from a road. Additional information defining the next path point following in the driving direction of the suggested route is transmitted in addition to route information at a path point.
