Abstract

A vehicle navigation system includes a navigation component (2), which includes a memory (4, 5, ?) for geographic data and a processor (8) for generating navigation information from the geographic data, and the system also includes a mobile phone (1) as a user interface for inputting requests to the navigation component and for displaying navigation information furnished by the navigation component (2).

Claims

1. A vehicle navigation system, having a navigation component (2), which includes a memory (4, 5, 11) for geographic data and a processor (8) for generating navigation information from the geographic data, and having a user interface (1) for inputting requests to the navigation component (2) and for displaying navigation information furnished by the navigation component (2), characterized in that the user interface is a mobile phone (1).

2. The vehicle navigation system of claim 1, characterized in that the mobile phone (1) is coupled to the navigation component (2) via a serial interface (3).

3. The vehicle navigation system of claim 1 or 2, characterized in that the mobile phone (1) is set up for outputting alphanumeric or graphic information, furnished by the navigation component (2), to a display field (15).

4. The vehicle navigation system of one of the foregoing claims, characterized in that the mobile phone (1) is connected to a hands-free system for outputting audio information furnished by the navigation component (2) and/or for inputting a request to the navigation component.

5. The vehicle navigation system of one of the foregoing claims, characterized in that the navigation component (2) further includes a memory (11) for terminal addresses that can be contacted with the aid of the mobile phone, and that the mobile phone (1) is set up for accessing this memory (11) in order to contact a distant terminal.

6. The vehicle navigation system of one of the foregoing claims, characterized in that it is set up to send, with the aid of the mobile phone (1), information pertaining to its current position that has been generated by the navigation component (2).

7. The vehicle navigation system of one of the foregoing claims, characterized in that the memory (4, 5, 11) of the navigation component (2) includes alphanumeric information, and that a filter (8) is provided for identifying terminal addresses that can be contacted with the aid of the mobile phone (1) in the alphanumeric information and for forwarding an identified terminal address to the mobile phone (1).

8. The vehicle navigation system of one of the foregoing claims, characterized by a transmission route for data, received by radio by the mobile phone (1), to the navigation component (2).

9. The vehicle navigation system of claim 8, characterized in that the navigation component (2) has a device (8) for identifying and evaluating data, received by radio by the mobile phone (1), of the kind that include supplementary geographic data.

10. The vehicle navigation system of claim 9 and claim 10, characterized in that program information that the navigation component (2) uses in evaluating the supplementary geographic data is also stored on the interchangeable data carrier.

11. The vehicle navigation system of claim 10 or 11, characterized in that the navigation component (2) is set up for forwarding a data set, stored on a data carrier placed in the reader unit (4), to the mobile phone (1) for broadcast.
