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.
