SYSTEM
• AV control unit calculates the vehicle location based
on the signals from GYRO (angle speed sensor), vehi-
cle 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 indica ted 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 dis-
tance the vehicle moved from the previous calculation point and its
direction.
• Travel distance Travel distance calculations are based on the vehicle speed sen-
sor input signal. Therefore, the calculation may become incorrect
as the tires wear down. To prevent this, an automatic distance cor-
rection function has been adopted.
• Travel direction
Change in the travel direction of the vehicle is calculated by a gyro-
scope (angular velocity sensor) and a GPS antenna (GPS informa-
tion). They have both advantages and disadvantages.
More accurate traveling direction is detected becaus e 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 Princi ple” 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 foll owing 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 cor-
rected manually.
SEL684V
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.

• In map-matching, alternative routes to reach the destination will be shown and prioritized, after the road on which the vehicle is cur-
rently driven has been judged and the vehicle mark has been repo-
sitioned.
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 alter-
nately, depending on maneuvering of the steering wheel and con-
figuration 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 direc-
tion 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 Posi tioning System)
GPS (Global Positioning System) is developed for and is controlled
by the US Department of Defense. The system utilizes GPS satel-
lites (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 (lati-
tude/longitude/altitude) according to the time lag of the radio waves
that four or more GPS satellites transmit (three-dimensional position-
ing). The GPS receiver calculates the travel position in two dimen-
sions (latitude/longitude) with the previous altitude data if the GPS
receiver receives only three radio waves (two-dimensional position-
ing). 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 pr ecision. 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 dimen-
sional 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 AND AUX IN JACK
•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.
• 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.

• Volume level of this system goes up and down aut
omatically 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 cont rol unit and output to the front speakers when operating
the cellular phone.
When A Call Is Originated
• Spoken voice sound output from the microphone (microphone signal) is input to AV control unit.
• AV control unit outputs to cellular phone with Bluetooth
® communication as a TEL voice signal.
• Voice sound is then heard at the other party.

AROUND VIEW MONITOR FUNCTION
• This system is equipped with wide-angle cameras on the front, rear and right and left door mirrors.
• Images from front view, rear view, front-side view ( RH side), and birds-eye view are displayed to monitor the
vehicle surroundings.
• Around view monitor control unit expands the image received from each camera to create each view.
• In front view and rear view, the vehicle width, dist ance lines and predictive course lines are displayed.
• In front-side view, the vehicle distance guiding line and vehicle width guiding line are displayed.
• Birds-eye view converts the images from the camera s into an overhead view and displays the status of the
