If the radio has this feature, it has either a Bose® sound system or a Bose® 5.1 Cabin Surround® sound system. DSP is used to provide a choice of different listening experiences.

To choose a DSP setting:

1. Press the TUNE/TONE knob to display the tone/speaker and DSP tabs.

2. Press the softkey under the DSP tab.

3. Press the softkey below the Back tab to return to the original tone/speaker display, or wait for the display to time out.

The DSP settings available are:

- Normal : Select for normal mode; this provides the best sound quality for all seating positions.

- Driver : Select to adjust the audio for the driver to receive the best possible sound quality.

- Rear : Select to adjust the audio for the rear seat passengers to receive the best possible sound quality.

- Centerpoint® : Select to enable Bose® Centerpoint signal processing circuitry. Centerpoint creates a Bose® surround sound listening experience from stereo CDs, MP3s, and satellite radio.

As a result, vehicle owners enjoy a surround sound listening experience from many audio sources. Simply turn it on, and it operates automatically.

This feature is not available in AM/FM radio mode.

If the vehicle is equipped with the Bose 5.1 Cabin Surround sound system, the radio can support the playback of 5.1 surround sound DVD-A discs or DTS 5.1 surround sound CD discs. When a 5.1 surround sound formatted disc is playing, DSP options available are:

– 5.1 Surround + Normal: Best for all seating positions.

– 5.1 Surround + Rear: Best for the rear seating positions.
