First, referring to FIG. 2, as the vehicle is started and the vehicle power is applied, the navigation system is powered on and initialized (S210).

Subsequently, after the vehicle occupant stores the driving path search and setting in the storage unit 300 through the key input unit 200, when the driving starts, the position detector 400 receives a signal of the GPS satellites applied from the GPS receiver 100. The location data is extracted from the current vehicle location data and the intersection (three-way or four-way, etc.) located in front of the driving road of the vehicle.

The vehicle position data and the intersection position data are compared with the driving route stored by the controller 800 to guide the driving route to the driver through the screen display unit 700 and the voice output unit 710 (S220).

If an intersection exists on the driving route during the driving route guidance (S230), a predetermined distance for entering the front intersection is extracted and a direction indication signal corresponding thereto is output. At this time, it is determined whether to turn left or right, not U-turn or P-turn, etc. at the intersection, and output a direction indication signal for turning on the direction indicator in the corresponding direction.

The direction indicator driver 500 lights up the left or right direction indicator by the direction indication signal (S240), and the abnormality detection unit 600 checks whether the direction indicator corresponding to the direction indication signal is actually turned on. (S250).

If there is an error in the corresponding direction indicator, the driver is notified through blinking that the screen display unit 700 is not turned on (S260).

On the other hand, the control unit 800 checks whether the current lane is a left-turn or right-turn lane based on the data signal input from the position detecting unit 400 when the turn signal is turned on (S310), and turns from the current lane.
