A navigation apparatus, in which guidance information for travel to a desired destination is outputted upon inputting the desired destination, has an input unit for inputting a desired destination, a memory unit for storing guidance information and destination information, and a display unit for outputting the guidance information and input information from the input unit, characterized in that the destination information has region name data and information data related to regions, and information data relating to a region is obtained by inputting the region name from the input unit. When input of the name of a prefecture, city or town for which a destination has not been specified is selected, a course search routine is executed in which a prefecture name list, city name list and town name list are retreived in order by the entry of prefecture name, city name and town name, the storage addresses of an intersection list and landmark list are obtained and an intersection at the destination is set. Accordingly, even in case of ambiguity where a destination cannot be specified, a concrete destination, such as a representative intersection or a representative landmark, is called from the ambiguous destination so that navigation to this destination can be performed.
