Playing the Radio
PWR (Power): Press this knob to turn the system on
and off.
VOL (Volume): Turn this knob to increase or to
decrease volume.
AUTO VOL (Automatic Volume): Your vehicle is
equipped with Bose AudioPilot noise compensation
technology. AudioPilot monitors the level of noise in the
vehicle and automatically increases and decreases
the level of the audio to keep your audio above
the noise.
To use this feature press the AUTO VOL button until
AVOL ON appears on the display. This feature
works best at lower volume settings where background
noise may be louder then the audio. At high volume
settings, where the audio is much louder then the
background noise, there will be no change in the audio
level. To turn automatic volume off, press this button
until AVOL OFF appears on the display.
DISPL (Display): Press this knob to switch the display
between the radio station frequency and the time.
Time display is available with the ignition turned off.
For RDS, press the DISPL knob to change what appears
on the display while using RDS. The display options
are station name, RDS station frequency, PTY, and the
name of the program (if available).
For XM™ (48 contiguous US states, if equipped),
press the DISPL knob while in XM mode to retrieve
four different categories of information related to
the current song or channel: Artist, Song Title, Category
or PTY, Channel Number/Channel Name.
To change the default on the display, press the DISPL
knob until you see the display you want, then hold
the knob for two seconds. The radio will produce
one beep and the selected display will now be the
default.
