• 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.

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.
