AUDIO SYSTEM

The audio system consists of the following components

• AV control unit

• A/C and AV switch assembly

• Display unit

AWNIA2810GB

[PREMIUM AUDIO WITH NAVIGATION]

SYSTEM

• Steering switches

• BOSE speaker amp.

• Center speaker

• Instrument panel tweeters

• Front tweeters

• Front door speakers

• Rear door tweeters

• Rear door speakers

• Rear side speakers

• Subwoofer

• Antenna

When the audio system is on, radio signals are received by the window antenna. The AV control unit then

sends audio signals to the BOSE speaker amp. The BOSE speaker amp. amplifies the audio signals before

sending them to the speakers, tweeters and subwoofer.

Refer to Owner's Manual for audio system operating instructions.

HANDS-FREE PHONE SYSTEM

System Operation

NOTE:
Cellular telephones must have their wireless connection set up (paired) before using the Bluetooth

telephone

system.
The Bluetooth

telephone system allows users who have a Bluetooth

cellular telephone to make a wireless

connection between their cellular telephone and the AV control unit. Hands-free cellular telephone calls can be
sent and received. Some Bluetooth

cellular telephones may not be recognized by the AV control unit. When

a cellular telephone or the AV control unit is replaced, the telephone must be paired with the AV control unit.

Different cellular telephones may have different pairing procedures, refer to the cellular telephone operating

manual.
Refer to the Owner's Manual for Bluetooth

telephone system operating instructions.

AV Control Unit

When the ignition switch is turned to ACC or ON, the AV control unit will power up. During power up, the AV

control unit is initialized and performs various self-checks. Initialization may take up to 20 seconds.

Steering Switches

When buttons on the steering switches are pushed, the resistance in steering switch circuits change, depend-

ing on which button is pushed.

The following functions can be performed using the steering switches:
• Initiate self-diagnosis of the Bluetooth

telephone system

• Answer and end telephone calls

• Adjust the volume of calls

• Record memos

Microphone

The microphone is located in the roof console assembly. The microphone sends a signal to the AV control unit.

The microphone can be actively tested during self-diagnosis.

NAVIGATION SYSTEM

System Operation

NOTE:

Refer to NAVI System Owner's Manual for system operation.

The navigation system periodically calculates the vehicle's current position according to the following three

signals: Travel distance of the vehicle as determined by the vehicle speed sensor, turning angle of the vehicle

as determined by the gyroscope (angular velocity sensor), and the direction of vehicle travel as determined by

the GPS antenna (GPS information).

The current position of the vehicle is then identified by comparing the calculated vehicle position with map data

read from the map data, which is stored in the hard disk drive (HDD) (map-matching), and indicated on the

screen with a current-location mark.
