Speed Compensated Volume (SCV): Radios with SCV automatically adjusts the radio volume to compensate for road and wind noise while driving. That way, the volume level should sound about the same while driving. To activate SCV: 1. Set the radio volume to the desired level. 2. Press the MENU button to display the radio setup menu. 3. Press the pushbutton under the AUTO VOLUM (automatic volume) tab on the radio display. 4. Press the pushbutton under the desired Speed Compensated Volume setting (OFF, Low, Med, or High) to select the level of radio volume compensation. The display times out after approximately 10 seconds. Each higher setting allows for more radio volume compensation at faster vehicle speeds. Press to turn the system on AudioPilot®: If the vehicle has the Bose® audio 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 or off. 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 information on AudioPilot, visit bose.com/audiopilot. 3-100
