The present invention relates to a navigation system in which that navigation system shows a configuration of a complicated intersection a driver is about to enter, and displays where to turn and a progression rate of the car on the path the driver is headed to. The navigation system comprises a Gyro sensor for detecting a rotation angle of the car; and route information from the Gyro sensor to generate the configuration of an intersection the user is supposed to enter and an arrow indicating a driving route to the user, and to display a progression rate of the car along the route; a display driving unit for displaying the configuration of the intersection and the arrow for route guidance, and a gradual progression rate of the car is indicated in the directional arrow.
