A method for transferring at least one navigation element from a vehicle
navigation unit to a master station. The vehicle navigation unit does not
include a database sufficient for a route calculation, including an input
device via which a user is able to input navigation element data
concerning at least one navigation element, the vehicle navigation unit
including communications devices, or cooperating with separate
communications devices, to exchange data with a master station in which
routes are calculated. The vehicle navigation unit includes an
arrangement to select at least one navigation element database entry, of
a plurality of navigation element database entries, which are transmitted
by the master station as response to the navigation element data
transmitted to the master station, when the master station is not able
uniquely to assign a plurality of navigation element database entries to
at least one navigation element.
