Abstract
A navigation system includes: a detection unit that detects a vehicle to be in a stationary state or in a traveling state; a display monitor at which a roadmap is displayed; and a manual route specification unit that allows a road traced on the display monitor to be specified as a route when the vehicle is detected to be in a stationary state by the detection unit and does not allow the road traced on the display monitor to be specified as the route when the vehicle is detected to be in a traveling state by the detection unit.
