SYSTEM DIAGRAM
AUDIO SYSTEM
The audio system consists of the following components
• Audio unit
• Front door speakers
• Rear door speakers
• Steering wheel audio control switches
• USB interface and AUX in jack
• Antenna base (antenna amp. and satellite antenna)
• Rod antenna
When the audio system is on, AM/FM signals received by the rod antenna are amplified by the antenna amp.
and sent to the audio unit. The audio unit then sends audio signals to the front door speakers and rear door
speakers.
Refer to Owner's Manual for audio system operating instructions.
HANDS-FREE PHONE SYSTEM
• Bluetooth® control is built into the audio unit.
• The connection between cellular phone and the audio unit is performed with Bluetooth
® communication.
• The voice guidance signal is input from the audio unit and output to the front speakers when operating the cellular phone.
When A Call Is Originated
• Spoken voice sound output from the microphone (microphone signal) is input to the audio unit.
• Audio unit outputs to cellular phone with Bluetooth
® communication as a TEL voice signal.
• Voice sound is then heard at the other party.
When Receiving A Call
• Voice sound is input to own cellular phone from the other party.
• TEL voice signal is input to the audio unit by establishing Bluetooth
® communication from cellular phone,
and the signal is output to front speakers.
REAR VIEW MONITOR
Camera Image Operation Principle
• The audio unit supplies power to the rear view camera when receiving a reverse signal.
• The rear view camera transmits camera images to the audio unit.
• The audio unit combines a warning message and fixed guide lines with an image received from the rear view camera.
