Audio System Description

Audio System Description

Overview

The audio unit acts as the processor for all audio functions. You can select of the audio functions from the front panel, the audio remote (on steering wheel), or by using the navigation voice control system. The audio display provides the current front and rear audio status. For vehicles with the navigation option, additional audio information is available by touching the audio button. (See the owner's manual for more details.)

Each audio component passes its audio signal to the audio unit. In addition, it communicates with the audio unit via the GA-Net bus. Any open connection in this circuit will cause audio and navigation functions to appear inoperative.

With the premium sound system, an audio amplifier unit powers the speakers, otherwise the speakers are powered directly by the audio unit.

The system includes an active noise cancellation system to cancel some of the vehicle noise. It uses a sine-wave-shaped sound output to cancel low frequency noise. Two microphones detect the low frequency sound, and the system outputs a canceling sound through the audio speakers.

The 6CD changer output can be directed to the audio unit.

The XM radio plays through the audio unit.

A security signal is daisy-chained between the audio and navigation components and integrated into the vehicle's alarm system.

The optional navigation system provides voice control for the front/rear audio, the XM, and the CD player. Voice control commands are communicated through the GA-Net (audio unit). When using the TALK/BACK or route guidance (RG), only the center speaker is muted and the front speakers give the navigation instructions. When using the HFL/AcuraLink, the center speaker, the rear speakers, and the subwoofer are muted and the front speakers give the telephone sound. When using the HFL/AcuraLink and the RG (Route Guidance) or voice response, the center speaker, the rear speakers, and the subwoofer are muted and the front speakers give the telephone sound and the navigation instructions. Muting commands are passed on the GA-Net bus. For more information, see the navigation section. The outline of the audio interruption function is shown in the following table.

Bluetooth Audio

Bluetooth audio allows music phones to play music via a car audio system using bluetooth technology.

You can control the phone's music player remotely using the wireless connection.

Bluetooth phones must be paired to the vehicle to use the bluetooth audio function.

- You can play music stored in your cell phone using the wireless connection*1

- You can choose next song, previous song and resume/pause via wireless*2

*1: The phone must support AVRC1.0, A2DP1.0 for bluetooth technology.

*2: Not all phones support the bluetooth audio function.

Supported Devices

- Bluetooth music phones that support AVRC1.0/A2DP1.0.

- Bluetooth adapters for portable music devices including iPod are not supported.

NOTE:

- Availability of the functions depends on the connected device.

- The latest support information is updated through the website handsfreelink.com.

Pairing a Cell Phone

You must pair an approved Bluetooth-compatible phone to the HFL system before you can make and receive calls. For a current list of approved phones and specific phone pairing instructions for each phone, see Checking Cell Phone Compatibility, go to handsfreelink.com. The following procedure works for most phones. If you cannot pair your phone to the HFL system with this procedure, refer to your phone's operating manual, visit handsfreelink.com.

NOTE:

- You cannot pair a phone while the vehicle is moving.

- Your phone must be in its Discovery mode.

- A maximum of six Bluetooth-compatible phones can be paired to the system.

1. With your phone on and the ignition switch in ACCESSORY (I) or ON (II), press and release the HFL TALK button. After the deep, say "Phone setup." The HFL responds, "Phone setup options are status, pair, edit, delete, and list."

2. Press and release the HFL TALK button. After the beep, say "Pair." The HFL responds, "The pairing process requires operation of your mobile phone. For safety, only perform this function while the vehicle is stopped. State a four-digit code for pairing. Note this code. It will be requested by the phone."

3. Press and release the HFL TALK button. After the beep, say the four-digit code you want to use. For example, say "1, 2, 3, 4." The HFL responds, "1, 2, 3, 4. Is this correct?"

4. Press and release the TALK button. After the beep, say "Yes." The HFL responds, "HFL is now searching for a Bluetooth phone. Make sure the phone you are trying to pair is in Discovery mode." If these steps do not works on the phone you are pairing, refer to the phone's operating manual.

5. Follow the prompts on your phone to get it into its Discovery mode. The phone will search for the HFL. When it comes up, select HandsFreeLink from the list of options displayed on your phone.

6. When asked by the phone, enter the four-digit code from step 3 into your phone. The HFL responds, "A new phone has been found. What would you like to name this phone?"
