A vehicle-mounted navigation device comprises an image display means which performs guiding of a direction of travel only by display of an arrow when a vehicle is running on a guided route and which performs map display instead of said arrow display when said vehicle is off the guided route.

Vehicle-mounted navigation device

A navigation system comprises a map information storage device for storing map data, a route setting device for setting a route between two points on the map data, target intersection detecting device for detecting a target intersection on the route from the set route and the map data, present position detector for detecting the present position of a mobile body, quantization computing device for quantizing the set route into simple graphics, and display for displaying the quantized route on a stepwise basis according to the distance between the nearest target intersection and the present position. The navigation system is capable of reducing the amount of distraction posed to a vehicle driver, is highly versatile and reduces the cost of the system.

Navigation system providing simplified navigation instructions using graphics and voice guidance to preferred routes and using landmarks

A method of navigating including decoding a position-information code represented by a string of codes including the latitude and the longitude of a position entered via an input means into original information on the position including the latitude and the longitude of the position. Information created from the recovered original information resulting from the decoding of the position-information code and map data read out from a map-information storage unit are presented to the user by using a display means and a sound outputting means.
