Abstract
A navigation apparatus provides a guidance about an exiting road of a circular intersection based on a prestored road and a learned road. The navigation apparatus determines whether or not the learned road is included in connection roads of the circular intersection. When the learned road is not included in the connection roads of the circular intersection, the navigation apparatus provides the guidance about the circular intersection in an exit number mode. When the learned road is included in the connection roads of the circular intersection, the navigation apparatus device provides the guidance about the circular intersection in a learned road guidance mode.
