COMPONENT PARTS
Steering Angle Sensor
INFOID:0000000011276791
• Steering sensor is installed to the spiral cable.
• Steering angle sends the steering signal necessary for predictive
course line via CAN communication.

SYSTEM DIAGRAM
AUDIO SYSTEM
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)
When the audio system is on, AM/FM signals received by the rod antenna are amplified by the antenna amp.
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), 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.

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 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 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 cor-
rected manually:
• 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.

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.
