Playing the Radio
VOL PWR: Press this control to turn the system on and
off. Turn this control clockwise to increase volume.
Turn it counterclockwise to decrease volume.
AUTO VOL: Your system has a feature called
Speed
- Compensated Volume (SCV). With SCV, your
audio system adjusts automatically to make up for road
and wind noise as you drive.
Set the volume at the desired level. Press AUTO VOL to
adjust the SCV. AVOL will appear on the display. Each
time you press AUTO VOL, another volume setting
(LOW, MEDIUM, HIGH or OFF) will appear on the
display. The volume level should always sound the same
to you as you drive. Each volume setting allows for
more volume compensation at faster vehicle speeds.
NONE will appear on the display if the radio cannot
determine the vehicle speed. If you don’t want to use
SCV, select OFF.
If your vehicle has the Bose radio, your audio system
monitors the noise inside your vehicle. Then, automatic
volume automatically adjusts the volume of your radio
so that it always sounds the same to you. To use
automatic volume, press the AUTO VOL button until
AVOL ON appears on the display. To turn the automatic
volume off, press the AUTO VOL button until AVOL
OFF appears on the display.
