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:

communicating a user defined destination with a communication unit for communicating the user defined destination through a communication link connected to a first device and a second device;

generating a reminder for announcing a reception of the user defined destination for communicating the reminder between the first device and the second device;

generating a first route from a first location to the user defined destination for navigating the first device from the first location to the user defined destination, where the first route includes a first line characteristic; and

generating with a control unit a second route from a second location to the user defined destination for navigating the second device from the second location to the user defined destination, where the second route includes a second line characteristic displayed different from the first line characteristic.

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

calculating a first estimated time of arrival for providing location based service associated with the first device and a second estimated time of arrival for providing location based service associated with the second device; and

communicating the first estimated time of arrival and the second estimated time of arrival for providing location based service with 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 waypoint; and

communicating the first revised route for navigating with 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

communicating the first revised route and the second revised route for navigating with the first device and the second device.

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

communicating a user defined destination with a communication unit for communicating the user defined destination through a communication link connected to a first device and a second device;

generating a reminder for announcing a reception of the user defined destination for announcing the reception by the second device to the first device;

generating a first route from a first location to the user defined destination for navigating the first device from the first location to the user defined destination, where the first route includes a first line characteristic;

generating a second route from a second location to the user defined destination for navigating the second device from the second location to the user defined destination, where the second route includes a second line characteristic displayed different from the first line characteristic; and

generating the reminder announcing a second estimated time of arrival and the second location for further updating the first device.

6. The method as claimed in claim 5 further comprising:

receiving a waypoint for updating the first route based on the waypoint from the second device;

generating a first revised route from the first route based on including the waypoint in traversing from the first location to the user defined destination; and

communicating the first revised route for displaying the first revised route on the first device, the second device, or a combination thereof.

7. The method as claimed in claim 5 wherein generating the reminder includes announcing a change in the second estimated time of arrival.

8. The method as claimed in claim 5 wherein generating the reminder includes announcing the second estimated time of arrival for providing location based service when the first device reaches a preselected distance from the user defined destination.

9. The method as claimed in claim 5 wherein generating the second route includes generating the second route including the second line characteristic for the line solidity, the line density, or a combination thereof different from the first line characteristic.

10. A navigation system comprising:

a communication unit for communicating a user defined destination for communicating the user defined destination through a communication link connected to a first device and a second device; and

a control unit, coupled to the communication unit, for;

generating a reminder for announcing a reception of the user defined destination for communicating the reminder between the first device and the second device;

generating a first route from a first location to the user defined destination for navigating the first device from the first location to the user defined destination, the first route including a first line characteristic; and

generating a second route from second location to the user defined destination for navigating the second device from the second location to the user defined destination, the second route including a second line characteristic displayed different from the first line characteristic.

11. The system as claimed in claim 10 wherein:

the control unit is for calculating a first estimated time of arrival and a second estimated time of arrival; and

wherein;

the communication unit is for communicating the first estimated time of arrival and the second estimated time of arrival for providing location based service with the first device and the second device.

12. The system as claimed in claim 10 wherein:

the control unit is for revising the first route based on a waypoint; and

the communication unit is for;

receiving the waypoint between the first location and the user defined destination, and

communicating the revised first route for navigating with the first device and the second device.

13. The system as claimed in claim 10 wherein:

the control unit is generating a first revised route and a second revised route based on revising the first route and the second route with a revised user defined destination; and

the communication unit is for;

receiving the revised user defined destination, and

communicating the revised first route and the revised second route for navigating with the first device and the second device.

14. The system as claimed in claim 10 the control unit is for:

generating the reminder for announcing the reception of the user defined destination by the second device to the first device; and

generating the reminder announcing a second estimated time of arrival and the second location for further updating the first device.

15. The system as claimed in claim 14 wherein the control unit is for generating the reminder announcing a reception of the user defined destination.

16. The system as claimed in claim 14 wherein the control unit is for generating the reminder announcing a change in the second estimated time of arrival.

17. The system as claimed in claim 14 wherein the control unit is for generating the reminder announcing the second estimated time of arrival for providing location based service when the first device reaches a preselected distance from the user defined destination.

18. The system as claimed in claim 14 wherein the control unit is for generating the second route including the second line characteristic for the line solidity, the line density, or a combination thereof different from the first line characteristic.
