The present invention relates to a navigation system using a remote control, and more particularly, to a navigation system using a remote control that can easily and quickly input the destination information into the navigation system.

In general, a navigation system, in conjunction with a GPS receiving system, displays a vehicle's current location on a map displayed on a display mounted on a vehicle, and furthermore, a driving guidance system that accurately guides the vehicle to the destination by displaying a route to the destination. And the like.

1 is a block diagram for explaining the configuration of a conventional navigation system.

The conventional navigation system shown in FIG. 1 includes a GPS module 14 for receiving GPS data from a GPS satellite via a GPS antenna 15, a map database 11 containing map data, and a keypad for outputting an operation signal. (12), a display 13 for displaying a map and a graphical user interface, and the like, and a GPS inputted from the GPS module 14 by using the map data of the map database 11 to display on the display 13. The control unit 10 is configured to display a current position or the like on the display 13 by using a signal and to display a destination route or the like on the display 13 by using data input from the keypad 12.

The keypad 12 is composed of a number key from 0 to 9 for data input, a plurality of character keys for character input, and a plurality of function keys for function control.

Conventional navigation system made as described above must input the address or name and GPS location information by operating the keypad 12 to search for a destination that the user wants to go.

For example, if the destination name is a 'canary part' located in Daechi-dong, Gangnam-gu, Seoul, Korea, and the name is input by a name search method, the keypad 12 is operated to sequentially input corresponding keys.

'ㄱ'-> 'ㅐ'-> 'ㄴ'-> 'ㅏ'-> 'ㄹ'-> 'ㅣ'-> 'ㅇ'-> 'ㅏ'-> 'ㅍ'-> 'ㅏ'-> 'ㅌ'-> 'ㅡ'-> 'Search'-> 'Enter'

In addition, even when the GPS location information is used, since the GPS location information of the 'Canary part' is 37 degrees 3 minutes 3.55 seconds in north latitude (N) and 127 degrees 3 minutes 1.66 seconds in longitude (E), it is sequentially inputted as follows.

'N'-> '3'-> '7'-> '3'-> '3'-> '5'-> '5'-> 'E'-> '1'-> '2'-> '7'-> '3'-> '1'-> '6'-> '6'-> 'Input'

However, in order to input data into the navigation system using the keypad as described above, since a large number of keys must be correctly and sequentially inputted, there is a problem in that operability is very inconvenient.

In addition, in the case where the location is impossible to search without knowing the GPS location information, there was a problem that data input is impossible.

Meanwhile, as illustrated in FIG. 2, a navigation system including a remote controller 27 capable of inputting data in addition to the keypad 22 has been conventionally proposed.

In FIG. 2, the reference numeral 20 is a control unit, 21 is a map database, 22 is a keypad, 23 is a display, 24 is a GPS module, 25 is a GPS antenna, and a signal of the remote controller 27 is connected to a control unit 20. 26).

Since the navigation system of FIG. 2 simply replaces the function of the keypad 12 illustrated in FIG. 1 with the remote controller 27, there is a problem in that data input is inconvenient and difficult to input location information that cannot be searched.
