AUDIO SYSTEM

• 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.

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 sig-
nal 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

®

 and iPod adapter with the wire harness. 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 out-
puts sound signal to BOSE amp. and BOSE amp. outputs 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.

• iPod

®

 connection status can be recognized whether iPod adapter receives iPod connection recognition sig-

nal.

• iPod adapter can charge iPod

®

.

Driver's Audio Stage Mode

• Driver's Audio Stage controls the speaker output characteristic by BOSE amp. so that driver seat is the cen-

ter of sound.

• ON/OFF signals of Driver's Audio Stage are transmitted from AV control unit to BOSE amp. using Mode sig-

nal.
