Operating Signal

Audio system operation 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 hardwire.
Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering switch.

Screen Display

Switching of display is performed with serial communication between display unit and AV control unit.
The image signal to display operating condition is performed with RGB image 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 to AV control unit. Audio signal is input to BOSE amp., and BOSE amp. outputs to each speaker.

Satellite Radio Mode

Satellite radio tuner is controlled by communication signal and request signal with AV control unit.
Sound signal (satellite radio) is received by satellite antenna and transmitted to AV control unit. AV control unit is output the sound signal (satellite radio) to each speaker.

CD Mode

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

USB Connection Function

iPod or music files in USB memory can be played.
iPod sound signals are transmitted from USB connector to the AV control unit and to each speaker.
iPod® is recharged when connected to USB connector.

iPod® is a trademark of Apple inc., registered in the U.S. and other countries.

NOTE: Use the enclosed USB harness when connecting iPod® to USB connector.

AudioPilot®

AudioPilot® is a sound improving system that picks up by a microphone in a driver headrest any noises or the sound of music coming into the vehicle, and that uses the BOSE amp. to revise the frequency feature of music in real time in response to the frequency feature of the noise while driving and listening to music.

If the low frequency area noise from the vehicle is loud, it adjusts the low frequency element of music to be larger than the vehicle noise.
If the high frequency area noise from the vehicle is loud, it adjusts the high frequency element of music to be larger than the vehicle noise.
If the vehicle noise is smaller than the setting volume, correction is not performed. This eliminates the vehicle noise when listening to music.

Sound Equalizer Automatic Switching Function

Sound quality in a fully-open retractable hard top condition is improved by the correction for bringing the frequency characteristics in a fully-open retractable hard top condition closer to the characteristics in a fully-closed retractable hard top condition. When the retractable hard top is in a fully-open condition, sound pressure is reduced due to the absence of sound echo generated by sound reflection from the retractable hard top. BOSE amp. detects an open-close condition of the retractable hard top by receiving a roof status signal from the retractable hard top control unit and switches the equalizer to correct the frequency characteristics in a fully-open retractable hard top condition. During the switching of the equalizer, audio stops temporarily due to the temporary mute.
