Abstract: When an area corresponding to area information is determined to use a default font, an ECU displays characters by using the default font stored in a ROM. When an area corresponding to area information is determined to not use a default font, the ECU reads out an exclusive font corresponding to the area to store it in a RAM, and displays characters by using the exclusive font stored in the RAM.

Abstract: A normal route guidance of a navigation apparatus based on guidance information retrieved from a hard disk drive is switched to a turn list display based on the guidance information from an external memory when a vehicle enters a high-altitude area. The navigation apparatus calculates a navigation route to a destination, and determines if the navigation route passes a high-altitude area. If the route passes the high-altitude area, the guidance information of a high-altitude area section of the navigation route is written in the eternal memory. Thus, while the vehicle is traveling, the navigation apparatus having the hard disk drive continues its navigation operation by displaying the turn list even when an operation of the hard disk drive is stopped due to a function restriction in the high-altitude area.

Abstract: With respect to a connection road linked with a rotary included in a guidance route, a vehicular navigation system acquires a dummy link that is defined to extend towards an inside of the rotary based on road map data. An advancing direction at the rotary is computed by using an angle defined by two dummy links with respect to both an entering road being the connection road on which the vehicle is to approach the rotary and an exiting road being the connection road on which the vehicle is to recede from the rotary. Guidance information at the rotary is outputted based on the computed advancing direction when the vehicle approaches the rotary.

Abstract: A navigation system for providing a navigation route of a travel between a start point and an end point based on a route search by using a predetermined condition includes a display unit for displaying the navigation route and/or a navigation route candidate with a condition name associated thereto. The predetermined condition with the condition name associated thereto yields a plurality of navigation route candidates as a result of the route search.
