Abstract

A navigation apparatus includes a current position detector that detects a current position and at least one controller. The at least one controller determines the administrative district where the current position is located, searches for at least one facility within each of a plurality of administrative districts that are substantially adjacent to the administrative district where the current position is located, and assigns each adjacent administrative district to a selection area on a search screen based on the direction from the current position to each facility within the plurality of adjacent administrative districts. A touch screen having buttons may be formed to represent the positional relationships between the current position and the adjacent administrative districts and enable the user to easily input commands for searching desired destination locations.

Description

technical field [0001] The present invention relates to a program of a navigation system and a location retrieval method. Background technique [0002] In conventional navigation devices, for example, GPS (Global Positioning System) detects the current position of the vehicle, that is, the current location, and at the same time detects the vehicle's orientation, That is, the vehicle orientation, the map data is read from the data recording unit, a map screen is formed on the display of the display unit, and the current location, the surrounding map, and the vehicle orientation are displayed on the map screen. Therefore, the driver, who is the operator, can drive the vehicle based on the current location, the surrounding map, and the direction of the vehicle displayed on the above-mentioned map screen. [0003] Furthermore, if the driver sets a destination and sets search conditions, it is possible to search for a route from the departure point indicated by the current locat...
