HANDS-FREE PHONE FUNCTION
 AV control unit includes hands-free phone function.
 Hands-free communication can be oper ated by connecting using Bluetooth
™ communication with cellular
phone.
 Operation is performed by steering switch, and operating condition is indicated on display.
 Guide sound that is heard during operation is input fr om AV control unit to BOSE amp., and is output from
front speaker and center speaker.
When A Call Is Originated
Spoken voice sound output from the microphone (microphone signal ) is input to AV control unit. AV control 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 output to door speaker, and
the signal is input to BOSE amp. via AV control unit by establishing Bluetooth
™ communication from cellular
phone.
TOUCH PANEL SYSTEM
Each operation of multi AV system can be perfo rmed by directly touching a front display.
AROUND VIEW MONITOR FUNCTION
 This system is equipped with wide-angle high-resolution cameras on the front and rear of the vehicle and on
both right and left door mirrors. The images from front view, rear view, front-side view (RH side), and birds-
eye view that shows the view from the top of the vehicle are displayed to monitor the vehicle surroundings.
 Around view monitor control unit cuts out and expands the image received from each camera to create each view.
 The sonar indicator is displayed on display (superimposed on the camera image) in combination with the
camera assistance sonar system to warm of the approach of an obstacle.
 In front view and rear view, the vehicle width, dist ance lines and predictive course lines are superimposed
and displayed. In front-side view, the vehicle distance guiding line and vehicle width guiding line are dis-
played.
 The Birds-Eye view converts the images from 4 cameras into the overhead view and displays the status of
the vehicle on display. The vehicle icon and sonar indica tor that are displayed on the Birds-Eye view display
are rendered by around view monitor control unit.
Around View Monitor Screen
 Around view monitor combines and displays the travel di rection view and “Birds-Eye view”, “Front-Side view”
and then it displays the sonar indicator on the “Birds -Eye view”, “Front-Side view”, “Rear wide view”.
 AV control unit renders the “Change View” switch, view icon, warning message on display.

Front view guiding lines
REAR VIEW The rear view image is from the rear camera.
 When the selector lever is in the reverse position, the rear view is displayed. Backing and parking are
improved by the images from Birds-Eye view and Front-S ide view. The rear wide view function allows the
display of an image with a 180 ° horizontal angle.
 Display the vehicle width guiding line and vehicle distance guiding line in Rear view and display the predic- tive course line according to the steering angle (except when using the rear wide view function).
 The predictive course line is not di splayed at the steering neutral position.
 AV control unit is connected to the steering angle s ensor and receives the steering angle signal via CAN
communication. AV control unit is transmits steering angle signal to around view monitor control unit via AV
communication.
 Around view monitor control unit controls the direction and distance of predictive course line according to the
sensor signal from steering angle sensor.
Rear view guiding lines
FRONT-SIDE VIEW
 The front-side view image is from the side camera RH.
 In Front-Side view, display the vehicle distance guiding line and vehicle width guiding line.
 The infrared LED illumination is installed on the door mirror RH to illuminate around the front wheels.
