Abstract

A method for operating a mobile navigation device in a vehicle. The vehicle is equipped with a radio device and wherein the navigation device encompasses at least one device for generating maneuvering instructions and a transmitter device for generating radio signals and wherein signals can be transmitted by the navigation device to the receiving part of the radio device by means of the transmitter device. The method includes the following method steps: a) computing a maneuvering display including a maneuvering instruction, which is to be displayed graphically; b) encoding the maneuvering display as a radio signal; and c) transmitting the maneuvering display, which is encoded as a radio signal, by the transmitter device of the navigation device, for transmitting the maneuvering display to the radio device.

Claims

1. A method for operating a mobile navigation device in a vehicle, wherein the vehicle is equipped with a first radio device and wherein the navigation device encompasses at least one device for generating maneuvering instructions and a transmitter device for generating radio signals and wherein signals can be transmitted by the navigation device to a receiving part of the radio device by means of the transmitter device, said method comprising the following method steps:

a) computing a maneuvering display including a maneuvering instruction, which is to be displayed graphically;

b) encoding the maneuvering display as a radio signal; and

c) transmitting the maneuvering display, which is encoded as a radio signal, by the transmitter device of the navigation device, for transmitting the maneuvering display to the radio device.

2. The method according to claim 1, in which the maneuvering display is encoded as a text message using letters, digits and special characters.

3. The method according to claim 1, in which the maneuvering display is encoded according to a Radio Data System (RDS) standard, in particular the maneuvering display is encoded as a Program Identification (PI) service according to the RDS standard.

4. The method according to claim 1, in which the maneuvering display includes arrow symbols for displaying a driving direction, in particular a turning direction of a next maneuver.

5. The method according to claim 1, in which the maneuvering display includes text information for displaying a distance to a next maneuver.

6. The method according to claim 5, in which the text information for displaying the distance to the next maneuver are updated dynamically.

7. The method according to claim 1, in which the maneuvering display includes data for describing a destination street of a next maneuver.

8. The method according to claim 1, in which the maneuvering display additionally includes data for describing speed limits and/or traffic information.

9. The method according to claim 1, in which the maneuvering display includes data for describing markers or direction signs, which are to be expected along a route which is computed by the navigation device.

10. The method according to claim 1, in which different components of the maneuvering display are transmitted and displayed in a chronologically offset manner.

11. The method according to claim 1, in which the navigation device comprises the functionality of a media player, in particular the functionality of a DVD player and/or the functionality of a CD player and/or the functionality of an MP3 player and/or the functionality of a Digital Video Broadcasting (DVB) player and in that media contents, which are to be output acoustically and/or optically, can be transmitted to the radio device by the navigation device as part of the radio signals.

12. The method according to claim 1, in which the navigation device comprises the functionality of a cellular phone and in that messages of the cellular phone, which are to be output acoustically, in particular dialog contents, which are to be output acoustically, can be transmitted to the radio device by the navigation device as part of the radio signals.

13. The method according to claim 1, in which the navigation device comprises the functionality of a second radio device and in that radio program contents, which are to be output acoustically, can be transmitted to the first radio device in the vehicle by the navigation device as part of the radio signals.

14. The method according to claim 1, in which the first radio device in the vehicle is connected to an external functional unit in the vehicle, in particular to a multifunction display in a dashboard of the vehicle, wherein the maneuvering display transmitted to the first radio device can be displayed on a display device of the external functional unit.

15. The method according to claim 1, in which the maneuvering display is transmitted and displayed for a longer period than an assigned acoustic maneuvering instruction.

16. The method according to claim 1, in which transmission of the maneuvering display is ended after a predetermined period and/or after a predetermined distance has been covered.
