A navigation device is provided with detailed map information of service areas and parking areas on freeways, and in the event that the vehicle to which the navigation device is mounted enters a service area for example while driving along the freeway which is a guided route, the navigation device reads out detailed map information of the service area which the vehicle has entered and displays a detailed map of this area such that the driver can readily understand the location of parking space, restaurants, stores, etc., and also displays the current position of the vehicle. Thus, in the event that the vehicle enters a service area or parking area while on a guided route, where what is within the area and where the vehicle is can be displayed in a readily understood manner, by the vehicle entering the area. |

DETAILED DESCRIPTION In light of the above problems, it is a first object of the present invention to display points of interest and the location of a vehicle within a service area or parking area which the vehicle has entered, in a manner that is readily understood.
It is a second object of the present invention to allow the vehicle to smoothly return to a portion of a guided route, such as a freeway, from the service area or parking area which the vehicle has entered.
It is a third object of the present invention to display, in a manner that is readily understood, the formation of the exit when the vehicle approaches the exit of the service area or parking area.
It is a fourth object of the present invention to display the location of desired stores and facilities, parking areas, and exits within a shopping mall which the vehicle or cursor has entered, in a manner that is readily recognized.
It is a fifth object of the present invention to allow the position of desired stores and facilities within the shopping mall to be readily recognized, and to allow these to be readily set as destinations.
It is a sixth object of the present invention to search routes to desired stores, facilities, and exits, so as to realize route guiding within the shopping mall.
It is a seventh object of the present invention to allow stores and facilities within a shopping mall to be set as destinations outside of the shopping mall, and performing route guiding toward the destination stores and facilities.
According to the present invention, the above first object is achieved by having detailed map information of inside freeway service areas and parking areas, and displaying detailed maps of within such an area in the event that the vehicle enters an arbitrary area while driving on a freeway which is a guiding route.
According to the present invention, the above second object is achieved by performing rerouting calculations in the event that the vehicle enters an area, and displaying a guiding route.
According to the present invention, the above third object is achieved by displaying the exit area in an enlarged manner in the event that the distance from the vehicle to the area exit is equal to or less than a certain distance while driving along the guiding route within the area, and also displaying the direction of progression
