In a vehicle navigation system, a data storage device stores data on
categories of points of interest indicated on sign boards provided at
freeway exits and facilities and services available at the points of
interest. The navigation system performs a search for a point of interest
that provides facilities or services specified by an input from a user in
a category specified by an input from the user based on the stored data.
The navigation system displays an exit at which a sign board including
the searched point is provided in a manner that the searched exit is
distinguishable from other exit on the display device. Furthermore, the
navigation system displays a route to the searched point of interest on
the display device.
