memory navi mode, the display will return to the map display mode used during the DVD navi mode when the DVD Map Disc is set again. • In memory navi mode, map scale data that cannot be read in the memory cannot be displayed. Accordingly, the edge of the map will appear cut off along the point it was not read into memory. This simply indicates the edge of the map data, and is not a malfunction. • If you keep driving or scrolling the map to a point where the map can no longer be displayed, the scale automatically switches to a range possible to display. If you would like to continue driving or scrolling the map at the same scale, set the DVD Map Disc in the navigation system. • You cannot reroute to avoid traffic congestion or closure. • If you continue to drive outside the route for a while, you may not be able to perform map matching. • If you deviate from the route during memory navi mode, set route will be rerouted, but only to return you to the original route calculated within the memorized area. • Although an enlarged map of the intersection will be displayed, no special freeway illustration (illustration of freeway intersections) will be displayed. • If the XM tuner (GEX-P10XMT, GEX-P920XM), which is sold separately, is connected, the logo data is not displayed during memory navi mode. Cautions relating to auto reroute in memory navi mode Auto rerouting in memory navi mode is designed to return you to your original route wherever possible. In memory navi mode, persistently deviating from the route may result in one of the following: • A clearly circuitous route • Leaving a toll road and returning to the toll road from where you left it. In the above case, if the set route seems unsuitable, insert the DVD Map Disc that records your current position. Setting the DVD Map Disc to navigation automatically resets the route from your current location to your destination. TRAFFIC icon during the memory navi mode • XM NavTraffic-related data for a "Zone" (e.g., Zone 1 contain ID, OR, WA) only can be memo- rized. Therefore, if appears on the screen when crossing a zone border, you will need to insert the disc to use the XM NavTraffic function. Touching allows you to check the locations of the traffic information along the route. However, you cannot perform rerouting. Operation outside the memorized area When the vehicle leaves the memorized area, the functions will be limited. • The auto reroute function does not work. • You can only display a larger scale map. The map display will automatically change to a 25 mi (or 50 mi) scale. • The map matching function will not be available. Therefore, the position of your vehicle may be misaligned. • The navigation guidance will only be available when arriving at your destination. Other guidance is not possible (this includes no display of direction arrows). To cancel these limitations, insert the DVD Map Disc to the navigation system. Positioning Technology The navigation system accurately measures your current location by combining the positioning by GPS and by Dead Reckoning. Positioning by GPS The Global Positioning System (GPS) uses a network of satellites orbiting the Earth. Each of the satellites, which orbit at a height of 68 900 000 feet (21 000 km), continually broadcasts radio signals giving time and position information. This ensures that signals from at least three can be 135 Appendix NAVI/AV
