Abstract
A navigation apparatus which includes an input section, a central processing section, a display section and a memory section is mounted on a moving object. When an initial or current position and destination of the moving object are provided to the central processing section, the apparatus produces two or more possible routes along which the moving object can move to reach the destination after starting from the current position by using map data stored in the memory section. The initial or current position, destination and possible routes are repeatedly calculated, updated and indicated on a screen of the display section. The two or more possible routes are repeatedly produced by a processor and calculation/retrieval circuitry. A connection route existing between the two or more possible routes may be retrieved and repeatedly indicated. Furthermore, a possible area containing the possible routes may be retrieved and repeatedly indicated.
