• An antenna base integrated with radio antenna and satellite radio
antenna is adopted.
System Description
INFOID:0000000005528458
MULTI AV system means that the following systems are integrated.
• AV control unit functions by transmitting/receiving data one by one with each unit (slave unit) that configures
them completely as a master unit by connecting between units that configure MULTI AV system with two AV
communication lines (H, L).
• Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
• AV control unit is connected by CAN communication, and it receives data signals from ECM and combina-
tion meter. It computes and displays fuel economy information value with the obtained information. Transmit-
ting/receiving of data signals are performed by BCM. Also, it transmits the required signal of vehicle setting
and receives the response signal.
• AV control unit is connected with front display unit and serial communication, and it transmits the required
signal of display and display control and receives the response signal from front display unit. It is also con-
nected with satellite radio by serial communication, transmits the operating signal and receives the display
signal.
NOTE:
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
• CONSULT-III self-diagnosis: refer to
AV-87, "CONSULT-III Function (MULTI AV)"
• On board self-diagnosis: refer to
AV-74, "Diagnosis Description"
On board self-diagnosis of TEL adapter unit can be performed.
• Refer to
AV-91, "Diagnosis Description"
for on board self-diagnosis.
AUXILIARY INPUT SYSTEM
• Image and sound can be output from an external device by connecting a device with auxiliary input jacks.
• Operation can be performed with multifunction switch and steering switch. Multifunction switch transmits
operation signal to AV control unit by AV communication.
Without DVD Entertainment System
• The AUX image signal is input from the auxiliary input jacks to the AV control unit. The AV control unit out-
puts AUX image signal to the front display unit.

MULTI AV SYSTEM
• The AUX sound signal is input from the auxiliary input jacks to the AV control unit. The AV control unit out-
puts the AUX sound signal to BOSE amp. The BOSE amp. outputs the AUX sound signal to woofer and
each speaker.
With DVD Entertainment System
• The AUX sound signal input from the external input device is transmitted from auxiliary input jacks to DVD
player. DVD player transmits it to AV control unit. AV control unit transmits the AUX sound signal to BOSE
amp. The BOSE amp. outputs the AUX sound signal to woofer and each speaker.
• The AUX image signal input from the external input device is transmitted to the video distributor. The video
distributor transmits the AUX image signal to the AV control unit and rear display unit.

Part name
Description
AV CONTROL UNIT
• It is the master unit of the MULTI AV system, and it is connected to each control
unit by communication. It operates each system according to communication
signals from the AV control unit.
• AV control unit includes audio function and vehicle information function.
• It is connected to ECM, A/C auto amp. and combination meter via CAN com-
munication to obtain necessary information for the vehicle information function.
• It is connected to BCM via CAN communication transmitting/receiving for the
vehicle settings function.
• It inputs the illumination signals that are required for the display dimming con-
trol.
• It inputs the signals for driving status recognition (vehicle speed, reverse and
parking brake).
• The camera image signal is input from the camera control unit. The AV control
unit outputs camera image signal to the front display unit.
• BOSE amp. ON signal and sound signal are transmitted to BOSE amp.
• Power (signal VCC and inverter VCC) is transmitted to front display unit.
Without DVD entertainment system
• Auxiliary image and auxiliary sound signals are input from the auxiliary input
jacks.
