Map Database Information and updates Map database is made based on the maps, 1999 edition of DENSO, whose information source comes from NavTech maps and GDT maps. In order to provide you with accurate map information as much as possible, we are always gathering information such as road repairs and doing site investigation. However, the names of roads, streets, facilities, and their locations are often changed. In some places, construction on roads may be in progress. For that reason, information on some areas in this system might be different from the actual location. The map database is normally updated once a year. Contact your dealer for updating a map database. E 1999 Navigation Technologies. All rights reserved. E GDT, Geographic Data Technology, Inc.

There are two types of areas which has been registered and none registered in a route guidance. (See page 39.) In the latter area, only the road is displayed on the map. The navigation do not show a route guidance to you, because the data (no right turns, one-way traffic, etc.) is not fixed. You should get your destination with an arrow which points a direction of your destination and a straight distance from the current vehicle position to your destination in that area. They are displayed on the bottom left of the screen.
