COMPONENT DESCRIPTION

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 communication 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 control. 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. With DVD entertainment system Composite image signal (auxiliary and DVD images) is input from the video distributor. Sound signal (DVD and auxiliary sounds) is input from the DVD player.
VIDEO DISTRIBUTOR	It receives the image signal from the DVD player, and auxiliary input jack, and then transmits it to the AV control unit and rear display unit. Composite synchronize signal is output to rear display unit. It transmits the headphone ON signal to the rear display unit, and then receives the remote controller operation signal from the rear display unit.
FRONT DISPLAY UNIT	Front display image is controlled by the serial communication from AV control unit. It receives the power (signal VCC and inverter VCC) from the AV control unit and operates. RGB image signal is input from AV control unit (RGB, RGB area and RGB synchronizing). Synchronizing signal (HP, VP) is output to AV control unit. Camera image signal is input from AV control unit. Without DVD entertainment system Auxiliary image signal is input from AV control unit. With DVD entertainment system Composite image signal (auxiliary and DVD images) is input from the AV control unit.
REAR DISPLAY UNIT	The rear display unit has functions of remote control receiver and headphone amp. Transmits the headphone sound signal when receiving headphone ON signal from the video distributor. Headphone sound signal is input from DVD player via wiring harnesses and outputs the signal to headphones via infrared wireless communication. Receives the operation signal from the remote controller and transmits the signal to the video distributor via serial communication. Rear display image is controlled by the serial communication from video distributor. RGB image signal is input from video distributor (RGB image and RGB area). Composite image signal (DVD and auxiliary images) is input from the video distributor. Synchronize signal (HP, VP) is output to video distributor.
DVD PLAYER	It transmits the playback DVD image signal to the video distributor. It transmits the playback DVD sound signal to the AV control unit. It also transmits the input AUX sound signal to the AV control unit.
BOSE AMP.	Inputs power (amp. ON) and sound signal from AV control unit, and outputs sound signal to woofer and each speaker. Woofer amp. ON signal is transmitted to woofer.
WOOFER	Composed of two woofers and a woofer amp. Inputs power (amp. ON) and sound signal from BOSE amp. Outputs low frequency sound.
FRONT DOOR SPEAKER	Outputs sound signal from BOSE amp. Outputs sound (mid and low range).
REAR DOOR SPEAKER	Outputs sound signal from BOSE amp. Outputs sound (mid and low range).
FRONT SQUAWKER	Outputs sound signal from BOSE amp. Outputs sound (high and mid range).
REAR SPEAKER	Outputs sound signal from BOSE amp. Outputs sound (high and mid range).
CENTER SPEAKER	Outputs sound signal from BOSE amp. Outputs sound (high and mid range).
MULTIFUNCTION SWITCH	Operation panel is equipped with the centralized switch where audio and auxiliary input operations are integrated. The multifunction switch is connected to the preset switch by wiring harness, and it transmits the operation signal to the preset switch.
PRESET SWITCH	Operation panel is equipped with the centralized switch where audio and air conditioner operations are integrated. The preset switch is connected via AV communication, and it transmits the operation signals of the preset switch and multifunction switch. The disk ejection operating signal is performed by wiring harness.
STEERING SWITCH	Operations such as audio and hands-free phone are possible. Steering switch signal (operation signal) is output to AV control unit.
MICROPHONE	Used only when hands-free phone is operated. Outputs Mic. signal (TEL voice signal) to the TEL adapter unit. The power (Mic. power supply) is supplied from the TEL adapter unit.
AUXILIARY INPUT JACKS	Without DVD entertainment system The image signal of the auxiliary input is output via the AV control unit to the front display, and it outputs the sound signal to the AV control unit. With DVD entertainment system The AUX image signal of the auxiliary input is output via the video distributor to the AV control unit and rear display unit, and it outputs the AUX sound signal to the DVD player.
ANTENNA BASE	A radio antenna base integrated with radio antenna amp. and satellite radio antenna is adopted. ANTENNA AMP. Radio signal received by rod antenna is amplified and transmitted to AV control unit. Power (antenna amp ON signal) is supplied from AV control unit. SATELLITE RADIO ANTENNA Receives the satellite radio wave and outputs it to the satellite radio tuner.
CAMERA CONTROL UNIT	Camera image signal is input from rear view camera. Camera image signal output to AV control unit. Power (camera ON signal) is transmitted to rear view camera. AV control unit recognizes the presence of camera system with camera connection recognition signal. Camera control unit is connected via AV communication.
REAR VIEW CAMERA	The image of vehicle rear view is transmitted to camera control unit. It receives the power (camera ON signal) from the camera control unit and operates.
STEERING ANGLE SENSOR	Steering signal necessary for possible route line control is transmitted to camera control unit.
TEL ADAPTER UNIT	Inputs the TEL voice signal from TEL antenna and outputs it to the AV control unit. It is connected with the AV control unit via AV communication and controlled with the AV control unit.
TEL ANTENNA	Receives the TEL voice signal and outputs it to the TEL adapter unit.
SATELLITE RADIO TUNER	Inputs the satellite radio signal from satellite radio antenna and outputs the sound signal to the AV control unit. It is controlled with the AV control unit and serial communication (communication signal and request signal).
iPod ADAPTER	Inputs iPod sound signal from iPod®, and outputs iPod sound signal to AV control unit. Receiving/transmitting of iPod® operation signals are performed as follows: between AV control unit and iPod adapter: AV communication. between iPod® and iPod adapter: serial communication.
