Abstract

A navigation system and method of exchanging location information through a messenger. The navigation system exchanging location information through a messenger, the navigation system includes a messenger program-installed navigation device which includes a communication device, transmits/receives messenger information including the location information to/from another navigation device, and displays the location information received through the message program on a map for route guidance.

Claims

1. A navigation system exchanging location information through a messenger, the navigation system comprises a messenger program-installed navigation device which includes a communication device, transmits/receives messenger information including the location information to/from another navigation device, and displays the location information received through the message program on a map for route guidance.

2. The navigation system of claim 1, wherein the messenger information includes destination information about a destination of the other navigation device, navigation device location information about a location of the navigation device, destination description information including text information about the destination, and communication information through the messenger.

3. The navigation system of claim 2, wherein the destination description information includes destination text information which is the text information about the destination, and destination alarm information which determines whether to display the destination text information when the destination is located a predetermined distance away.

4. The navigation system of claim 3, wherein the navigation device sets an alarm region, and when the navigation device moves into the alarm region, displays the destination text information, the alarm region having a radius which is the predetermined distance from the received destination information.

5. The navigation system of claim 2, wherein the navigation device retrieves a map between the received destination information and the location of the navigation device, and displays a shortest route based on the map.

6. The navigation system of claim 2, wherein the navigation device map-matches a map corresponding to the received navigation device location information to another navigation device location information, and displays the map with respect to a location of the navigation device and a map corresponding to the other navigation device location information, the other navigation device location information being location information about the other navigation device transmitting the navigation device location information.

7. The navigation system of claim 6, wherein the navigation device supports a screen division function, and simultaneously displays at least one map corresponding to a location of each of at least one navigation device.

8. The navigation system of claim 7, wherein the navigation device displays the navigation device and the other navigation device when the received navigation device location information can be displayed on the map where the location of the navigation device is matched, and divides a screen to simultaneously display the map of the navigation device and the map of the other navigation device when the received navigation device location information is too far away to be displayed on the map where the location of the navigation device is matched.

9. The navigation system of claim 3, wherein the navigation device includes a Text To Speech (TTS) function, and outputs the destination text information through voice.

10. The navigation system of claim 2, wherein the messenger program installed in the navigation device is installable in another device using a wired/wireless network.

11. The navigation system of claim 10, further comprising:

a network device which is connectable to a network, transmits/receives the destination information, the destination description information including the text information about the destination to/from the navigation device, and the conversion information through the messenger, the messenger program being installed in the network device.

12. The navigation system of claim 10, wherein the network device stores map information, or uses a map through a network using a web messenger installed in the network device.

13. A navigation method of exchanging location information through a messenger, the navigation method comprising:

receiving navigation device location information about a location of another navigation device;

determining whether the navigation device location information can be displayed on the map displayed in a navigation device;

retrieving a map corresponding to the navigation device location information;

dividing a screen of the navigation device, displaying the retrieved map corresponding to the navigation device location information in one part of a split screen of the navigation device, and a map currently displayed in the navigation device in another part of the split screen of the navigation device; and

additionally displaying a location corresponding to the navigation device location information on the map displayed in the navigation device.

14. The navigation method of claim 13, further comprising:

determining whether the location corresponding to the navigation device location information moves to a location which can be displayed on the map displayed in the navigation device; and

combining the screen of the navigation device and displaying a location of the navigation device and the location corresponding to the navigation device location information on the map.
