The audio system consists of the following component:

•  AV control unit
•  Front tweeters
•  Front door speakers
•  Rear door speakers
•  USB interface
•  AUX in jack
•  Steering switches
•  Antenna base (rod antenna, antenna amp. and satellite antenna)

and sent to the AV control unit. The AV control unit then sends audio signals to the front tweeters, front door speakers and rear door speakers.

Refer to Owner's Manual for audio system operating instructions.

NAVIGATION SYSTEM

Description

•  The navigation system can be operated by control panel of the AV control unit and display (touch panel) of the AV control unit
•  Guide sound during the operation of the navigation system is output from AV control unit to front tweeters.
•  AV control unit calculates the vehicle location based on the signals from GYRO (angle speed sensor), vehicle sensor, and GPS satellite, as well as the map data from map SD-card. The vehicle location is displayed on the AV control unit.

POSITION DETECTION PRINCIPLE

The navigation system periodically calculates the vehicle's current position according to the following three signals:

•  Travel distance of the vehicle as determined by the vehicle speed sensor
•  Turning angle of the vehicle as determined by the gyroscope (angular velocity sensor)
•  Direction of vehicle travel as determined by the GPS antenna (GPS information)

The current position of the vehicle is then identified by comparing the calculated vehicle position with map data read from the map SD-card (map-matching), and indicated on the screen as a vehicle mark. More accurate data is judged and used by comparing vehicle position detection results found by the GPS with the result by map-matching.

The current vehicle position will be calculated by detecting the distance the vehicle moved from the previous calculation point and its direction.

•  Travel distance
  Travel distance calculations are based on the vehicle speed sensor input signal. Therefore, the calculation may become incorrect as the tires wear down. To prevent this, an automatic distance correction function has been adopted.
•  Travel direction
  Change in the travel direction of the vehicle is calculated by a gyroscope (angular velocity sensor) and a GPS antenna (GPS information).

  They have both advantages and disadvantages.

Type	Advantage	Disadvantage
Gyroscope (angular velocity sensor)	Can detect the vehicle's turning angle quite accurately.	Direction errors may accumulate when vehicle is driven for long distances without stopping.
GPS antenna (GPS information)	Can detect the vehicle's travel direction (North/South/East/West).	Correct direction cannot be detected when vehicle speed is low.

More accurate traveling direction is detected because priorities are set for the signals from these two devices according to the situation.

MAP-MATCHING

Map-matching compares a current location detected by the method in the “Location Detection Principle” with a road map data from map SD-card.

NOTE: The road map data is based on data stored in the map SD-card.

The vehicle position may not be corrected under the following circumstances and after driving for a certain time when GPS information is difficult to receive. In this case, the vehicle mark on the display must be corrected manually.

•  In map-matching, alternative routes to reach the destination will be shown and prioritized, after the road on which the vehicle is currently driven has been judged and the vehicle mark has been repositioned.

  Alternative routes will be shown in different order of priority, and the incorrect road can be avoided if there is an error in distance and/or direction.

  Routes are of the same priority if two roads are running in parallel.

  Therefore, the vehicle mark may appear on either of them alternately, depending on maneuvering of the steering wheel and configuration of the road.

• Map-matching does not function correctly when a road on which the vehicle is driving is new and not recorded in the map SD-card, or when road pattern stored in the map data and the actual road pattern are different due to repair.

  The map-matching function may find another road and position the vehicle mark on it when driving on a road not present in the map.

  Then, the vehicle mark may change to it when the correct road is detected.

•  Effective range for comparing the vehicle position and travel direction calculated by the distance and direction with the road data read from the map SD-card is limited. Therefore, correction by map-matching is not possible when there is an excessive gap between current vehicle position and the position on the map.

GPS (Global Positioning System)

GPS (Global Positioning System) is developed for and is controlled by the US Department of Defense. The system utilizes GPS satellites (NAVSTAR), transmitting out radio waves while flying on an orbit around the earth at an altitude of approximately 21,000 km (13,049 mile).

The receiver calculates the travel position in three dimensions (latitude/ longitude/altitude) according to the time lag of the radio waves that four or more GPS satellites transmit (three-dimensional positioning).

The GPS receiver calculates the travel position in two dimensions (latitude/longitude) with the previous altitude data if the GPS receiver receives only three radio waves (two-dimensional positioning).

GPS position correction is not performed while stopping the vehicle.

Accuracy of the GPS will deteriorate under the following conditions:

•  In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes.
•  The position of GPS satellite affects GPS detection precision. The position detection may not be precisely performed.
•  The position detection is not performed if GPS receiver does not receive radio waves from GPS satellites.

  (Inside a tunnel, parking in a building, under an elevated highway etc.) GPS receiver may not receive radio waves from GPS satellites if any object is placed on the GPS antenna.

NOTE:

•  The detection result has an error of approximately 10 m (32.81 ft) even with a high-precision three dimensional positioning.
•  There may be cases when the accuracy is lowered and radio waves are stopped intentionally because the GPS satellite signal is controlled by the US trace control center.

USB INTERFACE

•  iPod® or music files in USB memory can be played.
•  Sound signals are transmitted from USB interface to the AV control unit and output to each speaker.
•  iPod® is recharged when connected to USB interface.

AUX IN JACK

•  Sound can be output from an external device by connecting a device to the AUX in jack.
•  AUX sound signals are transmitted to each speaker via AV control unit.

SPEED SENSITIVE VOLUME SYSTEM

•  Volume level of this system goes up and down automatically in proportion to the vehicle speed.
•  The control level can be selected by the customer.

HANDS-FREE PHONE SYSTEM

•  Bluetooth® control is built into AV control unit.
•  The connection between cellular phone and AV control unit is performed with Bluetooth® communication.
•  The voice guidance signal is input from the AV control unit and output to the front speakers when operating the cellular phone.
