A common word in Japanese syllabary is extracted from multiple items of the destination data, and the common words thus extracted are stored as search keywords. Furthermore, the search keywords are assigned to each potential destination which may be a search target. When a search is made for a destination, those keywords which match the input characters, in whole or in part, are extracted, and the keywords thus extracted are displayed as selectable keys, thus allowing the location candidates to be narrowed down based upon the input characters and the selected keywords. The priority levels of the extracted location candidates are adjusted according to priority score adjustment rules set by operator input, and the location candidates are displayed in the form of a list in descending order of priority. This allows the extracted location candidates to be displayed in the form of a list in an order matching the user's preference.
