MULTI AV SYSTEM
FUNCTION DIAGNOSIS
MULTI AV SYSTEM
System DiagramINFOID:0000000001728627
System DescriptionINFOID:0000000001728628
Multi AV system means that the following systems are integrated.
 Two AV communication lines (H, L) connect between units that configure MULTI AV system. NAVI control
unit controls by sending/receiving data one by one with each unit (slave unit) that configures them com-
pletely as a master unit.
 Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
 NAVI control unit is connected by CAN communication, and it receives data signal from ECM, combination
meter. It computes and displays fuel economy information value with the obtained information. Sending/
receiving of data signal is performed by BCM. Also, it sends the required signal of vehicle setting and
receives the response signal.

 NAVI control unit is connected with display and serial communication, and it sends the required signal of dis-
play and display control and receives the response signal from front display. Also, it is connected with satel-
lite radio by serial communication, and it sends the operating signal and receives the display signal.
NOTE:
NAVI control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
 CONSULT-III self diagnosis: Refer to AV-48, "
CONSULT - III Function (MULTI AV)".
 On board self diagnosis: Refer to AV-39, "
Diagnosis Description".
HANDS-FREE PHONE SYSTEM
 Hands-free communication can be operated by connecting using Bluetooth® with cellular phone.
 Operation is performed by steering switch, and operating condition is indicated on display.
 Guide sound that is heard during operation is input from NAVI control unit to audio unit and is output from
front speaker.
When a call is originated
Spoken voice sound output from the microphone (Mic. Signal) is input to NAVI control unit. NAVI control unit
outputs to cellular phone with Bluetooth
® communication as a TEL voice signal. Voice sound is then heard at
the other party.
When receiving a call
Voice sound is input to own cellular phone from the other party. TEL voice signal is output to front speaker, and
the signal is input to audio unit via NAVI control unit by establishing Bluetooth
® communication from cellular
phone.

NAVIGATION SYSTEM
Location 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 DVD-
ROM, which is stored in the DVD-ROM drive (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.
