Abstract
Disclosed is a method for enabling the user to easily and rapidly access a map image of a desired position in a navigation terminal. When a touch input through a touch screen is generated in a route guidance mode, a virtual scroll button having the form of a multi-directional keypad is displayed, and a dragging direction and a dragging displacement are calculated through the button. Then, map scrolling is performed according to the calculated dragging direction and dragging displacement, thereby displaying a corresponding map image. Accordingly, the user can easily and rapidly move the map image, making it possible to easily find a map image of a desired position.
