NOTE: A radio antenna base integrated with radio antenna and satellite radio antenna is adopted.

System Description
The audio system is equipped with the following functions. Each function can be operated by multifunction switch, preset switch or steering switch. It indicates the operation status of AUDIO to display.






FUNCTION DESCRIPTION

Operating signal
Operation of the audio system can be performed with multifunction switch, preset switch or steering switch.
- Operating signal is transmitted to AV control unit with AV communication when it is operated by multifunction switch or preset switch. The disk ejection operating signal is performed by hardware.
- Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering switch.

Screen display
- The display is switched by communication signal between display and AV control unit.
- The image signal that displays operating status is performed by the RGB signal, RGB area signal and RGB image synchronizing signal.

AM/FM Radio Mode
- AM/FM radio tuner is built into AV control unit.
- Audio signal is received by rod antenna, next it is amplified by antenna amp., and finally it is input into AV control unit. The FM sub antenna is installed on the back door window glass and AV control unit receives audio signal.
- Audio signal is input to BOSE amp., BOSE amp. outputs to woofer and each speaker from AV control unit.

Satellite Radio System
- Satellite radio tuner is controlled by serial communication and request signal from AV control unit.
- Satellite radio wave is received by satellite radio antenna and is input into satellite radio tuner. Satellite radio tuner outputs satellite radio sound signal to AV control unit. AV control unit outputs satellite radio sound signal to BOSE amp., BOSE amp. outputs the sound signal to each speaker and woofer.

CD Mode
- CD function is built into AV control unit.
- AV control unit outputs audio signals to BOSE amp., BOSE amp. outputs to woofer and each speaker when CD is inserted to AV control unit.

iPod Connection
- Connect iPod(R) and iPod adapter with the wire harness. iPod adapter inputs iPod sound signal from iPod(R).
When iPod mode is selected, iPod adapter outputs iPod sound signal to AV control unit. AV control unit outputs sound signal to BOSE amp. and BOSE amp. outputs sound signal to woofer and each speaker.
- Receiving/transmitting of iPod(R) operation signals are performed as follows:
- between AV control unit and iPod adapter: AV communication.
- between iPod(R) and iPod adapter: serial communication.

- iPod(R) connection status can be recognized whether iPod adapter receives iPod connection recognition signal.
- iPod adapter can charge iPod(R).

Driver's Audio Stage Mode
- Driver's Audio Stage controls the speaker output characteristic by BOSE amp. so that driver seat is the center of sound.
- ON/OFF signals of Driver's Audio Stage are transmitted from AV control unit to BOSE amp. using Mode signal.
