A method and a device are provided for outputting data records on the basis of input data records entered by a user, a set of data records present in a database being structured via a tree structure, and search criteria and filter information items being assigned to nodes in the tree structure which are not terminal nodes.

Searching a map database via a tree of nodes having multiple search criteria and filter items within a non terminal node

A storage medium on which geographic data of a geographic region are stored together as map units, a corresponding method for generating a map from the geographic data, and a corresponding navigation device. In order to reduce the amount of data to be processed, the map units are structured hierarchically, map units of an norder respectively corresponding to one geographic partial region, n being a natural number, and map units of an (n+1)order respectively corresponding to one geographic subregion of one of the partial regions.

Storage medium for map data, method for generating maps, and navigation device

In a method for the input of a destination, first of all a category selection is made, destinations corresponding to the category selection subsequently being offered for selection, at least a portion of the destinations being assigned to at least one subordinate category that, in each instance, has a superordinate category, characterized in that a category selection is made such that in each case, a superordinate category is displayed for the category selection or the superordinate category is replaced by one or the plurality of categories subordinate to it, and in each instance, a replacement is made when the number of subordinate categories with respect to a superordinate category is less than a predefined first threshold value.

Method for the input of a destination and navigation device

A method is proposed for entering place names into a device for processing the place names, in particular into a navigation device in a vehicle, where in the case that a match of a place name is ambiguous, a graphical representation for distinguishing the respective places of the same name is displayed for selection of the particular place.

Method for inputting local names

A navigation system including a drive for reading out navigation data which is stored on a data medium. In addition to the navigation data, a pregap is present on the data medium in which identification data is stored. The drive is designed in such a way that it is able to read CD information in the pregap and compares the identification data stored in the pregap to predefined data to allow or deny access to the navigation data.

Navigation system including a drive for reading out navigation data and a method for operating a navigation system

A driver information device with a map display is designed in such a way as to make the map display clear and easy to read. This is achieved, in cases where multiple special objects are situated at one location on the map, through the use of an indicator symbol representing such special objects, with a selection menu for selecting individual special objects, instead of displaying an individual symbol for each one of them.
