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. 3-67
