Abstract
A navigation system includes: a roadmap display unit that displays a roadmap at a display monitor; a current position detection unit that detects a current position of the navigation system; a setting unit that sets a right turn instruction or a left turn instruction for an intersection displayed in the roadmap; and a guidance unit that provides guidance based upon the right turn instruction or the left turn instruction having been set, as the detected current position moves to a point at or within a predetermined distance to the intersection having been set via the setting unit.
