If the vehicle has the Bose
system, it has AudioPilot noise compensation
technology.
To use AudioPilot:
1. Set the radio volume to the desired level.
2. Press the MENU button to display the radio
setup menu.
3. Press the pushbutton located under the AUTO
VOLUM tab on the radio display.
4. Press the ON or OFF button to turn this feature on

When turned ON, AudioPilot continuously adjusts
the audio system equalization, to compensate for
background noise, so that the music always sounds
the same at the set volume level.
The feature is most effective at lower radio volume
settings where background noise can affect how well
you hear the music being played through the vehicle's
audio system. At high volume settings there might be
little or no adjustments by AudioPilot. For more
