Radio With Cassette And Cd - GMC 2004 Sonoma Owner's Manual

Radio with Cassette and CD

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): With automatic
volume, your audio system adjusts automatically
to make up for road and wind noise as you drive.
Set the volume at the desired level. Press this button to
select LOW, MEDIUM, or HIGH. AVOL will appear
on the display. Each higher setting will allow for more
volume compensation at faster vehicle speeds. Then as
you drive, automatic volume increases the volume as
necessary to overcome noise at any speed. The volume
level should always sound the same to you as you
drive. NONE will appear on the display if the radio
cannot determine the vehicle speed. If you don't want to
use automatic volume, select OFF.
DISP (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 DISP 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).
To change the default on the display, press the DISP
knob until you see the display you want, then hold
the knob for two seconds. The radio will produce one
beep and selected display will now be the default.
