Audio System Description

Overview

There are two audio systems available for the TSX:

- The premium audio system is on vehicles without navigation. It includes six speakers, a subwoofer, and an XM receiver.

- The ELS audio system is available on vehicles with navigation. It includes surround sound with nine speakers (the same six that are available on the premium audio system, plus one in each rear door and in the middle of the front dash), a subwoofer, and AcuraLink control unit (XM receiver).

The audio unit acts as the processor for all audio functions. You can select the audio functions from the front panel, the audio remote (on the 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.

The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio preset data (AM/FM radio frequency, sound settings, etc.) even when the battery is disconnected.

With the ELS and the premium audio system, a stereo amplifier powers the speakers.

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 security system.

The optional navigation system provides voice control for the audio, the XM, and the CD player. Voice control commands are communicated through the GA-Net (audio unit). When using the navigation TALK/BACK or route guidance (RG), the center speaker is muted and you hear the navigation instructions through the front speakers. 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 HFL/AcuraLink and the RG (Route Guidance) or the navigation TALK/BACK, the center speaker, the rear speakers, and the subwoofer are muted and you hear the telephone sound and navigation instructions through the front speakers. 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 approved Bluetooth cell phones equipped with music function to play music via a car audio system using Bluetooth technology. You can control the phone's music player remotely using the wireless connection.

- You can play music in your device via wireless connection*1.

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

*1: The cell phone must support AVRCP1.0, A2DP1.0 for Bluetooth technology, and also be on the Acura approved HFL list at www.acura.com/handsfreelink.

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

Supported Devices

- Bluetooth music phones that support AVRCP1.0/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 www.acura.com/handsfreelink.

Pairing a cell phone

To pair a cell phone, refer to pairing a cell phone in the HandsFreeLink system '09 model, Initial Inspection and Diagnostic Overview '10 model Initial Inspection and Diagnostic Overview phone is paired, the process does not have to be repeated for the phone.

How to play the Bluetooth Audio

1. Push the AUX button to select Bluetooth Audio source.
NOTE:

- If you push the AUX button when no cell phone is connected, NO CONNECT is displayed.

- If you see NO CONNECT when you are using the cell phone music function, check that the device is properly paired. If it is paired, the cell phone may not be compatible. See www.acura.com/handsfreelink for more information.

- Music titles and artist names are not displayed.

2. Start the music player in the paired device.
NOTE: Depending on the cell phone, the music may start automatically, or a user may need to manually select headset as an audio output.

3. A user can remotely select Next Song or Previous Song using the SKIP button.

4. A user can remotely select pause and resume by selecting [RESUME/PAUSE] in AUDIO MENU using the interface dial.
