Audio Function

The audio system is equipped with the following functions. Each function is operated with multifunction switch, preset switch, touch panel, steering switch or voice recognition. Operation status of audio is indicated at front display unit.

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 wiring harness.
• Operating signal is transmitted to AV control unit with steering switch signal when it is operated by steering switch.
• Refer to the following system description ("VOICE RECOGNITION FUNCTION " and "TOUCH PANEL SYSTEM ") for explanation of voice recognition function and touch panel function.

Screen Display

Switching of display is performed with serial communication between display unit and AV control unit.

AM/FM Radio Mode

• AM/FM radio tuner is built into AV control unit.
• Audio signal is received by glass 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 woofer and each speaker. (coupe models)
• 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. (roadster models)

Satellite Radio Mode

• Satellite radio tuner is built into AV control unit.
• Audio wave (satellite radio) is received by satellite radio 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 woofer and each speaker. (coupe models)
• Audio wave (satellite radio) is received by satellite radio 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 each speaker. (roadster models)

CD Mode

• CD function is built into AV control unit.
• AV control unit outputs audio signal to BOSE amp., and BOSE amp. outputs to woofer and each speaker. (coupe models)
• AV control unit outputs audio signal to BOSE amp., and BOSE amp. outputs to each speaker. (roadster models)

Bluetooth™ Audio

• Bluetooth™ audio function is built into AV control unit.
• When the Bluetooth™ audio is connected to the portable audio equipped with the Bluetooth™ communication compliant profile via Bluetooth™ communication, it can be play the music data in the portable audio.
• A maximum of five Bluetooth™ devices including the audio devices and cellular phones can be registered in the AV control unit.

Music Box Mode

• Music CD data is stored on HDD (Hard Disk Drive) that is built into AV control unit, and it can be played.
• AV control unit outputs music (sound signal) that is stored on HDD (Hard Disk Drive) to BOSE amp., and BOSE amp. outputs to woofer and each speaker. (coupe models)
• AV control unit outputs music (sound signal) that is stored on HDD (Hard Disk Drive) to BOSE amp., and BOSE amp. outputs to each speaker. (roadster models)

Sound Equalizer Automatic Switching Function

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