PROBLEM TO BE SOLVED: To provide a navigation system that can search a guiding route even when a destination, etc., is not strictly designated. SOLUTION: A processing and control section 5 acquires information that vaguely designates the destination (for example, 'in the vicinity ofΔΔΔTower') through a voice recognizing section 8. Then the section 5 extracts the candidates of the destination decided from the acquired information from a CD-ROM 4 and sets the candidate meeting a prescribed condition as the destination from among the candidates. In addition, the section 5 acquires information that vaguely designates a transit place (for example, 'along×××Road') through the voice recognizing section 8. Then the section 5 extracts a plurality of candidates for the transit place decided from the acquired information from the CD-ROM 4 and sets the candidate meeting a prescribed condition from among the candidates. In addition, the section 5 searches the guiding route from road network information recorded on the CD-ROM 4 in accordance with the set destination, etc. |
