< FUNCTION DIAGNOSIS >[AUDIO SYSTEM]
AUDIO SYSTEM
The audio system consists of the following components
• AV control unit
• Display unit
• BOSE speaker amp.
• Window antenna
• Steering wheel audio control switches
• A/C and AV switch assembly
• Rear audio and remote control unit
• Front door speakers
• Front tweeters
• Center speaker
• Rear door speakers
• Rear door tweeters
• Back door speakers
• Subwoofer
When the audio system is on, radio signals are receiv
ed by the window antenna. The AV control unit then
sends audio signals to the BOSE speaker amp. The BO SE speaker amp. amplifies the audio signals before
sending them to the front door speakers, front tweeters, center speaker, rear door speakers, rear door tweet-
ers, back door speakers and the subwoofer.
Refer to Owner's Manual for audio system operating instructions.
SATELLITE RADIO SYSTEM
The satellite radio system consists of the following components
• Satellite antenna
• AV control unit
When the satellite radio system is on, radio signals are supplied to the AV contro l unit from the satellite
antenna. The AV control unit then sends audio signals to the BOSE speaker amp.
Refer to Owner's Manual for satellite radio system operating instructions.
SPEED SENSITIVE VOLUME SYSTEM
Volume level of this system goes up and down automatically in proportion to the vehicle speed. The control
level can be selected by the customer. Refer to Owner's Manual for operating instructions.
