<p>A control circuit (29) of a navigation apparatus (1) acquires exit port information in a rotary intersection for route guidance (S101). It is determined whether a guidance point or guidance target used as an exit path from the rotary intersection is a learned road acquired by the road learning function (S102). When the exit path is not a learned road (S102: NO), namely, when the exit path is an existing road in a ready-made map data, an "exit path guidance for existing roads" aimed at an exit port to an existing road is executed (S103). In contrast, when the exit path from the rotary intersection is a learned road (S102: YES), an "exit path guidance for learned roads" aimed at an exit port to a learned road is executed (S104).
