A vehicle navigation apparatus displays an expressway guide diagram indicating the names of plural exits at which a travelling vehicle can exit an expressway and the distance and estimated arrival time to each of the exits. The expressway guide diagram includes a map display for indicating a display of a surrounding-area map of an exit. When the map display is operated, the display scale of the surrounding-area map is determined so as to contain a predetermined number of representative facilities, and the surrounding-area map is displayed on a display device according to the display scale. Therefore, with respect to each exit at which the vehicle can get off the expressway, a map based on the proper display scale corresponding to the positional relationship between each exit and facilities can be displayed.

When a control circuit extracts data of an entity corresponding to a phone number, the control circuit retrieves phone numbers that accord, with respect to lower seven digits of a phone number, with the inputted phone number from among phone numbers included in retrieval data. After the entity having the phone number corresponding to the inputted phone number is extracted, a map including the entity extracted is displayed based on the position information of the entity extracted. Accordingly, even when the area code of the phone number is changed, the map including the corresponding entity can be displayed.
