1. A method for transferring at least one navigation element, especially a road name and/or a place name, from a vehicle navigation unit to a master station, having the following steps:
- a) entering navigation element data which relate to at least one navigation element, into the vehicle navigation unit, b) transmitting entered navigation element data to a master station via an online connection between the vehicle navigation unit and the master station, c) comparing the transmitted navigation element data to navigation element database entries available in the master station, and differentiating between at least the following cases;
Case 1;
a navigation element database entry may be uniquely assigned to the transmitted navigation element data, with respect to each navigation element that is included, Case 2;
a plurality of navigation element database entries is not able to be uniquely assigned to the transmitted navigation element data, at least with respect to one navigation element, Case 3;
no navigation element database entry is able to be assigned to the transmitted navigation element data, at least with respect to one navigation element,
in case 2, the master station transmitting at least some of the plurality of the navigation element database entries, that are not uniquely assignable, via an online connection to the vehicle navigation unit, wherein an additional selection point is offered to the user in Case 2 which may be selected by the user if none of the plurality of navigation element database entries, that were transmitted and are not uniquely assignable, is applicable.

Abstract
The present invention relates to a method for transferring at least one navigation element from a vehicle navigation unit to a master station. The present invention also relates to a vehicle navigation unit, as well as a master station.
The vehicle navigation unit is a vehicle navigation unit which does not have a database sufficient for a route calculation, having an input device via which a user is able to input navigation element data concerning at least one navigation element, the vehicle navigation unit having communications devices, or cooperating with separate communications devices, to exchange data with a master station in which routes are calculated.
According to the present invention it is provided that the vehicle navigation unit has means using which the user may 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.
