Navigation system for use in passenger car, has map plotting device plotting three-dimensional map with destination guiding line using determined position, where line represents route in map using vector map data

摘要

The system has height detecting device for detecting height of a route between start and end points in a three-dimensional map. A position determining device determines a position of a destination guiding line in the map based on the route height. A map plotting device (8g) plots the map with the guiding line using the position, where the line represents the route in the three-dimensional map using vector map data.
