Navigation device and method providing a traffic message channel resource

1. A navigation system for selecting a traffic message channel, the navigation system comprising:

a receiver to determine a signal strength of a traffic message channel at a location;

a memory to store information representing the signal strength of the traffic message channel; and

at least one processor to correlate the information stored in memory to compile a traffic message channel resource and select a traffic message channel based on the traffic message channel resource and a location associated with a navigation device.

2. The navigation system of claim 1 wherein a first processor correlates the information stored in memory to compile the traffic message channel resource and a second processor selects a traffic message channel based on the traffic message channel resource and the location associated with a navigation device.

3. The navigation system of claim 2 wherein the first processor is included in a central system and the second processor is included in a navigation device.

4. The navigation system of claim 1 wherein the at least one processor is included in the navigation device.

5. The navigation system of claim 1 wherein the location associated with a navigation device is a current location of the navigation device.

6. The navigation system of claim 1 wherein the location associated with a navigation device is an expected location of the navigation device.

7. The navigation system of claim 1 wherein the traffic message channel resource designates a traffic message channel as preferred.

8. The navigation system of claim 7 wherein the traffic message channel resource designates a preferred traffic message channel is based on at least one of a radio station location, a radio station coverage, a planned route, information provided by a user of a navigation device, and information provided by the traffic message channel provider.

9. The navigation system of claim 1 wherein the selected traffic message channel is based on at least one of a radio station location, a radio station coverage, a planned route, information provided by another navigation device user, and information provided by the traffic message channel provider.

10. A method for selecting a traffic message channel, the navigation system comprising:

determining a signal strength of a traffic message channel at a location;

storing information representing the signal strength of the traffic message channel;

correlating the information stored in memory to compile a traffic message channel resource; and

selecting a traffic message channel based on the traffic message channel resource and a location associated with a navigation device.

11. The method of claim 10 wherein the location associated with a navigation device is an expected location of the navigation device.

12. A navigation device to perform the method of claim 10 .

13. A navigation system for selecting a traffic message channel, the navigation system comprising:

means for measuring a signal strength of a traffic message channel;

means for storing information representing the signal strength of the traffic message channel at the location of a navigation device;

means for correlating the information stored in memory to compile a traffic message channel resource; and

means for selecting a traffic message channel based on the traffic message channel resource and a current location of a navigation device.

14. The navigation system of claim 13 wherein the means for correlating is included in a central system and the means for selecting is included in a navigation device..
