The system has a position detection device, a destination selection device with an input unit (12) within the vehicle (11), a topological data memory (13) with information about topological conditions in a defined area of the Earth's surface and a display in the vehicle for displaying a relationship between the current vehicle position and the selected destination. The topological data memory is connected to an external, preferably central server (15) that can communicate via a mobile network (16) with navigation system units (17) within the vehicle An Independent claim is also included for a method of operating a navigation system.
