A navigation system performs route guidance with map information, which is suited for use in navigating a vehicle or other movable object. The system includes a user interface in which starting point and destination are input to a service provider. A service provider determines the route between the starting point and destination and generates driving directions and map images for one or more turning points along the routes. Map images near the turning points are displayed to the user, along with the driving directions for each turning point. A mark indicating the position of the vehicle itself is superimposed on the map image that is displayed to the driver.
