• Signals necessary for the vehicle information display function are received from ECM and the combination meter via CAN communication.
• 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.
• The AV control unit contains an HDD with map data and sensors used for automatic location calculation, i.e. a gyroscope (angular velocity sensor) and a G sensor.
  • HDD
• The AV control unit records map data, traffic regulations data, and guidance information.
  • Gyroscope
• Detects vehicle cornering condition.
  • Acceleration sensor
• Detects the inclination angle and height variation of the vehicle.

HDD

• The adoption of a fast high-capacity 40 GB HDD improves the navigation performance.
• The adoption of the music box function enables the recording of music data to HDD and the storing of approximately 3, 000 tracks at a maximum.

AM/FM Electronic Tuner

The adoption of the PLL frequency synthesizer system enables the signal outputting with accurate frequencies.

Satellite Radio Tuner

• The adoption of the PLL frequency synthesizer system enables the signal outputting with accurate frequencies.
• Receives satellite radio antenna signal and converts it into the sound signal and data signal.
• It outputs sound signal to BOSE amp. and outputs data signal to front display unit.

CD/DVD drive

• It is CD-R/CD-RW compliant and enables MP3, WMA, and AAC files to play music.
• It displays the artist name, album title or song title recorded to the file by the ID3 tag/WMA tag/AAC tag display function.
• DVD playback function is equipped.

USB Interface

• Music can be played by connecting an iPod® or USB memory.

Camera Controller

• Warning message, width/distance guiding line and predictive course line are generated on the image from the rear view camera.
• The predictive course 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 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.
