Component Description

AUDIO UNIT




Base System
- It receives the TEL voice signal and voice guidance signal from AV (NAVI) control unit and output them to the front speaker.
- When the TEL voice and voice guidance is output, it controls the volume of each speaker.




BOSE 2ch System
It receives the TEL voice signal from AV (NAVI) control unit and output it to the BOSE amp.




BOSE Surround 5.1ch System
- It receives the TEL voice signal from AV (NAVI) control unit and output it to the BOSE amp.
- DVD player receives the received AUX sound and the down-mix sound of DVD player, and then sends them to the BOSE amp.

BOSE AMP




BOSE 2ch System
- It amplifies the sound signal from the audio unit and output it to each speaker.
- It receives the voice guidance signal from AV (NAVI) control unit and output it to the front speaker.
- It controls sound volume of each speaker when outputting TEL voice and voice guidance.
- It subjects to AudioPilot(r) processing when receiving sound signal from microphone for AudioPilot(r).

BOSE Surround 5.1ch System




- It amplifies the sound signal from the audio unit and the DVD sound signal from DVD player, and then output them to each speaker.
- It receives the voice guidance signal from AV (NAVI) control unit and output it to the front speaker.
- It controls sound volume of each speaker when outputting TEL voice and voice guidance.
- It subjects to AudioPilot(r) processing when receiving sound signal from microphone for AudioPilot(r).
- It subjects to Centerpoint(r) processing.




SATELLITE TUNER
- The satellite tuner is connected with the audio unit via communication line.
- It sends the received sound signal from the satellite radio antenna to the audio unit.




AV CONTROL UNIT (WITHOUT NAVI)
- It controls each unit of the system by the operation signal from the multifunction switch and sends the image signal of operating condition or vehicle information, etc. to the front display unit.
- It receives the TEL input voice or the input voice at voice control from the microphone. It receives the received TEL voice, and then sends it to the audio unit.
- It sends the voice guidance signal to BOSE amp (BOSE system) and audio unit (BASE system).




NAVI CONTROL UNIT (WITH NAVI)
- It controls each unit of the system by the operation signal from the multifunction switch and sends the image signal of operating condition or vehicle information, etc. to the front display unit.
- It receives the TEL input voice or the input voice at voice control from the microphone. It receives the received TEL voice, and then sends it to the audio unit.
- It sends the voice guidance signal to BOSE amp (BOSE system) and audio unit (BASE system).
- Signals are received from the gyro, the vehicle speed sensor, and the GPS antenna. Vehicle location is determined by combining this data with the data contained in the DVD-ROM map. Location information is shown on liquid crystal display panel.




FRONT DISPLAY UNIT
- It receives the RGB signal and the image signal of DVD player and camera control unit from AV (NAVI) control unit.
- The changing of image is controlled by the communication with AV (NAVI) control unit.




DVD PLAYER
- It sends the sound signal to the BOSE amp and sends the image signal to the front display unit.
- When the down-mix function is turned ON when playing DVD, the sound signal is sent to the audio unit.
- It inputs the sound signal from auxiliary input jacks, and then sends it to audio unit.




CAMERA CONTROL UNIT
- When the reverse signal is input, the power is supplied to the rear view camera, and then the image signal from the rear view camera is sent to the front display unit.
- The camera control unit displays the guiding lines and possible route lines, and then it synthesizes them to the camera image.

CAN Communication System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
