Rear Seat Audio (Rsa) - GMC 2005 Safari Owner's Manual

Rear Seat Audio (RSA)

This feature allows rear seat passengers to listen to any
of the sources: radio and CDs. However, the rear
seat passengers can only control the sources that the
front seat passengers are not listening to. For example,
rear seat passengers may listen to and control a CD
through headphones while the driver listens to the radio
through the front speakers. The rear seat passengers
have control of the volume for each set of headphones.
The front seat audio controls always have priority
over the RSA controls. If the front seat passengers
switch the source for the main radio to a remote source,
the RSA will not be able to control the remote source.
You can operate the RSA when the main radio is off.
PWR (Power): Press this button to turn the system on
or off. The rear speakers will be muted when the
power is turned on.
VOL (Volume): Press this knob lightly so it extends.
Turn the knob to increase or to decrease the volume.
Push the knob back into it's stored position when
you are not using it. The upper knob controls the upper
headphones and the lower knob controls the lower
headphones.
