COMPONENT PARTS

AV Control Unit


DESCRIPTION






- High-resolution 7-inch wide VGA display integrated AV control unit is installed at the center of the instrument panel.
- The AV control unit is equipped with the following parts. It is the master unit integrated with functions and controls the multi-AV system.





- Signals necessary for the vehicle information display function are received from ECM and the combination meter via CAN communication.
- It is connected to TCU in USB communication, and signals necessary for the Telematics function and CARWINGS function are sent and received.
- Signals necessary for vehicle setting functions are sent and received with BCM via CAN communication.
- It inputs the signal for driving status recognition (vehicle speed signal, reverse signal, and parking brake signal).
- A possible route line is generated on the camera image from the rear view camera, and it is shown on the display.
- It has the built-in gyro sensor and acceleration sensor as a vehicle position calculation sensor. Map data is read from an SD card in the SD slot.
- SD card
- It records the map data, traffic control data, and guide information, etc.
- Gyroscope
- Detects vehicle cornering condition.
- Acceleration sensor
- Detects the inclination angle and height variation of the vehicle.
NOTE:
For details of each functions, refer to "MULTI AV SYSTEM : System Description" System Description.
SD Card Slot
With the display opened, the map card slot is located on the right (main slot), and the card slot used for import/
export of stored location is located on the left (sub slot).
Display
- High resolution 7-inch wide VGA LCD monitor is adopted to display a high definition image including digital image signals.
- Touch panel function is adopted to improve operability.
- RGB digital image signals (navigation image/menu image) and composite image signals (rear view camera image) are displayed.
Audio Amplifier
- 45W x 4ch amplifiers are installed.
- Audio sound, TEL voice and guiding voice are output to each speaker.
AM/FM Electronic Tuner
- The AM/FM electric tuner includes the PLL frequency synthesizer system.
Satellite Radio Tuner
- The adoption of the PPL synthesizer method allows the signal reception at more accurate frequencies.
- The satellite radio tuner receives a satellite radio antenna signal and converts the signal into an audio sound signal and a data signal.
- The audio sound signal is transmitted to the audio amplifier and the data signal is transmitted to the display.
CD Drive
- It is CD-R/CD-RW compliant and enables MP3 and WMA files to play music.
- It displays the artist name, album title or song title recorded to the file by the ID3 tag/WMA tag display function.
USB Interface
- Music can be played by connecting an iPod� or USB memory.
Camera Controller
- Warning message, width/distance guiding line and possible route line are generated on the image from the rear view camera.
- The possible route line is drawn based on the steering signal received from the steering sensor via CAN
communication.
Bluetooth�Module
- Wireless connection to the audio device equipped with Bluetooth�communication can play music.
- Once a Bluetooth� communication compliant phone has been registered in the AV control unit, hands-free phone communication and connection to the CARWINGS information center can be carried out without connecting the cellular phone to the TEL harness.
- Five units of Bluetooth� communication devices including audio devices and cellular phones can be registered to the AV control unit.
