A navigation system marks a route to a destination ordestinations on a map, guiding the user along the routeto the destination.Vehicle positioning system GPS (Global Positioning System)The positioning system uses communications satelliteslaunched by the US Department of Defense. Signals arereceived from three or more satellites orbiting at 21 000km altitude, and the principle of triangulation is used tofi nd the position.By receiving GPS signals, this system can position thevehicle within a margin of error of 30 to 200 m.Time before the current position is foundWhen this system is used for the fi rst time, or if ithas not been used for an extended period, it may takeas much as 5 minutes to fi nd the current position. Innormal conditions, at a location with good reception,positioning takes around 2 minutes.Starting to move the vehicle immediately after turning onthe power causes it to take longer to find the position, sothe user is advised to remain parked in a location withgood reception (with no buildings or trees to block thesignals from GPS satellites) until the current position isfound. Locations where GPS signal receptionis diffi cultReception may not be possible in locations such as thefollowing: In tunnels Between tall buildings Under elevated roads Between trees Map matchingThis function displays the vehicle position obtained fromGPS, the gyro sensor and other sources on the map.What is a navigation system?Vehicle positioning precisionThe vehicle mark position may not be displayedcorrectly due to the driving environment and theGPS satellite status.Continue driving without taking further action, and themap matching function and GPS satellite data will beused to automatically correct the vehicle mark position. When a highway and an ordinary road are closetogether When driving through a fork junction with a narrowangle between roads When driving on roads in a block grid pattern After moving on a ferry, car transporter, etc. When driving on steep mountain roads When driving on winding roads When turning right or left after driving on a straightroad for a long period When driving in a weaving motion on a wide roadThe vehicle mark position may not be displayed correctlyin the following additional situations: Between turning the ignition switch on (after turningthe power on) and receiving GPS signals. When driving for the fi rst time after installing thissystem. After changing a tire, particularly when driving on anemergency tire. When driving on roads that are slippery due to snow,gravel etc., or when driving with tire chains. When the vehicle emerges onto a normal road afterdriving on a spiral route out of an underground ormulti-story parking lot, or when the vehicle was turnedon a turntable after stopping the engine (turning thepower off). GPS satellites are under the control of the USDepartment of Defense, which may deliberately reducepositioning precision. In such situations, the vehiclemark not refl ect the actual position of the vehicle.Road on the mapdataRoute trace derived from sensorsActual pathScreen displayPoint corrected by map matchingEnglish110110
