CURRENT VEHICLE LOCATION DISPLAY OF CURRENT VEHICLE LOCATION This navigation system combines the data obtained from the vehicle (by gyro sensor) and from GPS (Global Positioning System) satellites to calculate the current location of the vehicle. This position is then displayed throughout route guidance to a destination. Map data is available on the provided SD-card. For information about the map SD-card, contact a NISSAN dealer or call the NISSAN NAVIGATION SYSTEM HELPDESK. See the contact information on the inside front cover of this manual. Map data includes 2 types of areas: "Detailed coverage areas" providing all detailed road data and other areas showing "Main roads only". NOTE: Detailed map data is not available in many areas and is generally limited to select major metropolitan areas. ROUTE CALCULATION ● The NISSAN Navigation System may not calculate a route if the current vehicle location is too far away from the destination. In this case, please divide your trip by selecting one or two intermediate destinations. ● To reach your destination, refer to the map screen. Always follow actual roads and regulations and drive safely. ● The suggested route may not be the shortest, nor are other circumstances such as traffic jams considered unless the SiriusXM Traffic is active. ● Because of the inevitable difference in road conditions and circumstances between the time you use this system and the time the information was produced for the map data, there may be discrepancies in roads and regulations. In such cases, follow the actual information available. ● During route calculation, the map will not scroll, however the vehicle icon will move with the actual vehicle's movement. ● In some cases, after the calculation is complete, the calculated route may not be immediately displayed. ● If you scroll the map while the suggested route is being drawn, it may take more time to finish drawing. WHAT IS GPS (Global Positioning System)? GPS is a position detecting system that uses satellites deployed by the U.S. government. This navigation system receives radio signals from three or more different satellites that orbit 13,049 miles (21,000 km) above the earth in space, and detects the position of the vehicle by utilizing the principle of triangulation. WHEN A GRAY ROAD IS DISPLAYED ON THE MAP ● Route calculation may not be possible when a destination or the current vehicle location is near a gray road. ● Route guidance (enlarged view and voice guidance) may not be available at the intersection where the road your vehicle is driving on and a gray road intersect. ● Places information and street names near gray roads are not contained in the map data. DETAILED MAP COVERAGE (MCA) FOR THE NAVIGATION SYSTEM This system is designed to help you reach your destination, and also performs other functions as outlined in this manual. However, you, the driver, must use the system safely and properly. Information concerning road conditions, traffic signs and the availability of services may not always be up-to-date. The system is not a substitute for safe, proper, and legal driving. 6-4 General system information
