ABSTRACT:
A position input system for a vehicular navigation apparatus includes an input unit for inputting a desired destination and a present position, a memory unit for storing desired destination information and map information, and a display unit for outputting the desired destination information and map information in response to input information from the input unit. The map information is indicative of intersections and a geographical point located between intersections and possessing useful guidance information. A desired destination and present position are capable of being inputted by setting the useful guidance information between a road leading to and a road leading from the geographical point. This makes it possible to enter position simply and accurately. Positions are precise since they are selected from pre-stored information relating to geographical locations. Vehicle direction can also be inputted in accurate fashion where parking lot exits and intersections are concerned.
