Abstract

A method of operation of a navigation system includes: operating a communication unit for establishing a communication link between a first device and a second device; receiving a user defined destination; displaying a first location and a first route to the user defined destination on the first device and the second device, where the first location represents the location of the first device; and displaying a second location and a second route to the user defined destination on the first device and the second device, where the second location represents the location of the second device.

Claims

1. A method of operation of a navigation system comprising:

operating a communication unit for establishing a communication link between a first device and a second device;

receiving a user defined destination;

displaying a first location and a first route to the user defined destination on the first device and the second device, where the first location represents the location of the first device; and

displaying a second location and a second route to the user defined destination on the first device and the second device, where the second location represents the location of the second device.

2. The method as claimed in claim 1 further comprising:

calculating a first estimated time of arrival for the first device and a second estimated time of arrival for the second device; and

displaying the first estimated time of arrival and the second estimated time of arrival on the first device and the second device.

3. The method as claimed in claim 1 further comprising:

receiving a waypoint between the first location and the user defined destination;

generating a first revised route from the first route based on the location of the waypoint; and

displaying the first revised route on the first device and the second device.

4. The method as claimed in claim 1 further comprising:

receiving a revised user defined destination;

generating a first revised route and a second revised route from the first route and the second route, respectively, based on the revised user defined destination; and

displaying the first revised route and the second revised route on the first device and the second device.

5. The method as claimed in claim 1 wherein displaying the first route includes displaying the first route with a line characteristic that is different from the line characteristic of the second route.

6. A method of operation of a navigation system comprising:

operating a communication unit for establishing a communication link between a first device and a second device;

receiving a user defined destination;

displaying a first location and a first route to the user defined destination on the first device and the second device, where the first location represents the location of the first device;

displaying a second location and a second route to the user defined destination on the first device and the second device, where the second location represents the location of the second device; and

generating a reminder announcing a second estimated time of arrival and the second location.

7. The method as claimed in claim 6 wherein generating the reminder includes announcing a reception of the user defined destination.

8. The method as claimed in claim 6 wherein generating the reminder includes announcing a change in the second estimated time of arrival.

9. The method as claimed in claim 6 wherein generating the reminder includes announcing the second estimated time of arrival when the first device reaches a preselected distance from the user defined destination.

10. The method as claimed in claim 6 wherein providing the communication unit includes providing the communication unit for establishing a communication link among the first device, the second device, and an intermediate device.

11. A navigation system comprising:

a communication unit for establishing a communication link between a first device and a second device, including;

a communication interface for receiving a user defined destination; and

a display interface, coupled to the communication unit, for displaying a first location and a first route to the user defined destination, and a second location and a second route to the user defined destination on the first device and the second device.

12. The system as claimed in claim 11 further comprising:

a control unit, coupled to the communication unit, for calculating a first estimated time of arrival and a second estimated time of arrival; and

wherein;

the display interface is for displaying the first estimated time of arrival and the second estimated time of arrival on the first device and the second device.

13. The system as claimed in claim 11 further comprising:

a control unit, coupled to the communication unit, for revising the first route based on a waypoint; and

wherein;

the communication interface is for receiving a waypoint between the first location and the user defined destination; and

the display interface is for displaying the revised first route on the first device and the second device.

14. The system as claimed in claim 11 further comprising:

a control unit, coupled to the communication unit, for revising the first route and the second route based on a revised user defined destination; and

wherein;

the communication interface is for receiving the revised user defined destination; and

the display interface for displaying a revised first route and a revised second route on the first device and the second device.

15. The system as claimed in claim 11 wherein the display interface is for displaying the first route with a line characteristic that is different from the line characteristic of the second route.

16. The system as claimed in claim 11 further comprising a control unit, coupled to the communication unit, for generating a reminder announcing a second estimated time of arrival and the second location.

17. The system as claimed in claim 16 wherein the control unit is for generating the reminder announcing a reception of the user defined destination.

18. The system as claimed in claim 16 wherein the control unit is for generating the reminder announcing a change in the second estimated time of arrival.

19. The system as claimed in claim 16 wherein the control unit is for generating the reminder announcing the second estimated time of arrival when the first device reaches a preselected distance from the user defined destination.

20. The system as claimed in claim 16 wherein the communication unit is for establishing a communication link among the first device, the second device, and an intermediate device.
