Operating Signal
Audio system operation can be performed with multifunction switch, preset switch, steering switch, touch panel function or voice recognition function.
- 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 hardwire.
- Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering switch.
- Refer to Navigation (Twin Monitor) for explanation of voice recognition function and touch panel function.

Screen Display
- The display is switched by communication signal between front display unit and AV control unit.
- The image signal that displays operating status is performed by the RGB image signal, RGB area signal and
RGB 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. and BOSE amp. outputs to woofer and each speaker for AV control unit.

Satellite Radio Mode
- Satellite radio tuner is built into AV control unit.
- Audio signal (satellite radio) is received by satellite antenna, and it is input to AV control unit. AV control unit outputs audio signal to BOSE amp. The signal is also outputted from BOSE amp. to both woofer and each speaker.

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

Music Box Mode
- Music CD data is stored on HDD that is built into AV control unit, and it can be played.
- AV control unit outputs music (audio signal) that is stored on HDD to BOSE amp., and BOSE amp. outputs to woofer and each speaker.

CF Mode
- AV control unit has built in CF replay function.
- Music (audio signal) that is stored in CF outputs to BOSE amp. and BOSE amp. outputs to woofer and each speaker when CF is inserted into AV control unit.

iPod Connection
- Connect iPod� and iPod adapter with wire harness and iPod adapter inputs iPod sound signal from iPod�.
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. output sound signal to woofer and each speaker.
- 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.
- The iPod� connection status can be recognized whether iPod adapter receives iPod connection recognition signal.
- The iPod adapter can charge iPod�.

Driver's Audio Stage Mode
