A navigation system includes: an intersection enlargement creation unit that creates based upon map data an intersection enlargement over a predetermined map range around a target guidance-requiring intersection present on a recommended route, at which a turn should be made; an intersection enlargement display unit that displays at a display monitor the intersection enlargement having been created by the intersection enlargement creation unit; and a mark display unit that displays an indicator mark indicating an advancing path shape at a next guidance-requiring intersection immediately beyond the target guidance-requiring intersection over the intersection enlargement on display at the display monitor.
