Abstract:
PROBLEM TO BE SOLVED: To provide a navigation apparatus by which a dropping-in installation which agrees with a user's desire can be selected simply and quickly by a method wherein, during a running operation up to a destination, only a dropping-in installation existing along a route is extracted and displayed. SOLUTION: Installations around a retrieval point are sorted by designating a type. The shortest straight distance between the sorted installations and a route which is searched in advance is computed (Step SD1). Only the installations whose computed shortest straight distance exists within 150m are extracted (Step SD2). The right position and the left position, with reference to the advance direction of a route, of every extracted installation are detected (Step SD3). A distance up to a destination along a guide route is found in every installation (Step SD4). According to the found distance up to the destination, respective installation data are rearranged (Step SD5).
