When a facility is specified from a facility list indicating facilities which satisfy a facility searching condition, a path searching processing section searches for a driving path with the specified facility being set as a destination, and obtains information such as driving distance and driving time required when a vehicle travels the driving path to the destination. A text-information generating and drawing section generates drawing data for displaying text information, such as the driving distance and the driving time, and stores the drawing data in a VRAM. A map drawing section generates drawing data for displaying a map image of an area which includes the driving path and stores the drawing data in the VRAM. An image synthesis section synthesizes the drawing data stored in the VRAM and the drawing data supplied from an operation-screen generation section, and causes a display apparatus to display a search image which includes the facility list, the text information, and the map image on one screen.
