A navigation system for a movable body wherein a map to be displayed on a screen can be selected freely in accordance with a request of an operator and, when an initial map displayed is restored, the operator can find out a current position of the movable body readily. The navigation system comprises a memory in which map data are stored, a position detector for detecting a current position of the movable body, and a display unit having a screen on which a map based on part of the map data and a current position mark based on a current position from the position detector are normally displayed on the screen. When an operator wants to see an adjacent portion contiguous to the map displayed, one of four scroll key patterns displayed on the screen is selectively touched to cause the map and current position mark on the screen to be scrolled. If a map returning pattern displayed on the screen is touched, the initial map is restored and the current position mark is displayed in position on the map. If the current position mark is out of position then, a correction pattern on the screen is touched to cause the current position mark to be displayed in position on the map.
