Abstract
In a vehicular navigation system, an electronic control unit uses in its recommended vehicle travel path determination processing restricted-type roads the data of which is less reliable than those of normal roads. A display device indicates the recommended travel path on a road map displayed thereon. When a vehicle travels on the restricted-type road, a travel guidance specific to the restricted-type road is issued to notify a driver of traveling on the restricted-type road and thereby invite the driver to decide himself or herself. The guidance may be in a vocal announcement from a speaker and/or a visual display on the display device.
