Abstract

In a radio signal receiver for motor vehicles with a radio receiver with an RDS decoder for digital signals, convertible via a table into traffic information, the signals can be forwarded from the decoder via a data link to a navigation system provided with a route data storage which generates the traffic information from the signals.

Claims

1. A radio signal receiver for a motor vehicle, comprising:

a radio receiver having an RDS decoder which decodes digital signals that are convertible through the use of a table into traffic information;

a navigation system having a route data storage, said navigation system containing said table; and

a data link which forwards said digital signals from said RDS decoder to said navigation system, wherein said navigation system uses said table to generate the traffic information;

wherein said navigation system enters said traffic information into a map section being displayed.

2. The radio signal receiver according to claim 1, wherein said navigation system enters said traffic information into a planned route of said map section being displayed.

3. The radio signal receiver according to claim 2, wherein said radio signal receiver further includes a storage device for at least some of said digital signals.

4. The radio signal receiver according to claim 1, wherein said radio signal receiver further includes a storage device for at least some of said digital signals.

5. A radio signal receiver for a motor vehicle, comprising:

a radio receiver having an RDS decoder which decodes digital signals that are convertible through the use of a table into traffic information;

a navigation system having a route data storage, said navigation system containing said table; and

a data link which forwards said digital signals from said RDS decoder to said navigation system, wherein said navigation system uses said table to generate the traffic information;

wherein said navigation system further comprises a speech storage system which converts said traffic information into acoustic information;

wherein said navigation system enters said traffic information into a map section being displayed.

6. The radio signal receiver according to claim 5, wherein said radio signal receiver further includes a storage device for at least some of said digital signals.

7. The radio signal receiver according to claim 5, wherein said navigation system enters said traffic information into a planned route of said map section being displayed.

8. A radio signal receiver for a motor vehicle, comprising:

a radio receiver having an RDS decoder which decodes digital signals that are convertible through the use of a table into traffic information;

a navigation system having a route data storage, said navigation system containing said table; and

a data link which forwards said digital signals from said RDS decoder to said navigation system, wherein said navigation system uses said table to generate the traffic information;

wherein said navigation system includes a display which outputs said traffic information;

wherein said navigation system enters said traffic information into a map section being displayed.

9. The radio signal receiver according to claim 8, wherein said radio signal receiver further includes a storage device for at least some of said digital signals.

10. The radio signal receiver according to claim 8, wherein said navigation system enters said traffic information into a planned route of said map section being displayed.
