MULTI AV SYSTEM


WITH NAVIGATION : System Description

Multi AV system means that the following systems are integrated.










- AV control unit function 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 signal from ECM, unified meter and A/C amp. It computes and displays fuel economy information value with the obtained information. Transmitting/receiving of data signal is 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 via serial communication, and it transmits the required signal of display and display control and receives the response signal from display.

NOTE:
AV control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
- CONSULT-III self diagnosis: Refer to Consult-III Function (Multi AV).
- On board self diagnosis: Refer to Diagnosis Description.

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.

With Navigation
- The AUX image signal is input from the auxiliary input jacks to the front display unit.
- The AUX sound signal is input from the auxiliary input jacks to the AV control unit. The AV control unit outputs the AUX sound signal to the BOSE amp. The BOSE amp. output the AUX sound signal to each speaker.

With Navigation And DVD Player
- The AUX image signal is input from the auxiliary input jacks to the DVD player. The DVD player outputs the
AUX image signal to the front display unit.
- The AUX sound signal is input from the auxiliary input jacks to the DVD player. The DVD player outputs the
AUX sound signal to the AV control unit. The AV control unit outputs the AUX sound signal to the BOSE amp., and the BOSE amp. outputs to each speaker.

VOICE RECOGNITION SYSTEM
- Each operation of multi AV system can be performed by inputting sound to microphone.
- Start of sound recognition system can be performed by steering switch.

TOUCH PANEL SYSTEM
Each operation of multi AV system can be performed by directly touching a display.
