BASIC FUNCTIONS In order to provide you with accurate map information as much as possible, we are always gathering information such as on road repairs and carrying out on−site investigations. 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. "DVD": To determine which version of the database is currently in your vehicle, select the "DVD" switch on the "Menu" screen. The "DVD information" screen appears and displays the map database version. ROUTE GUIDANCE AVAILABILITY Route guidance available area for detailed roads and for main roads are provided. The software covers the route guidance available area as shown in the following "Route guidance availability" illustrations. Route guidance available areas may change due to the upgrading of the map data. The map database is normally updated once a year. Contact your Toyota dealer for information about the availability and pricing of an update. 71
