2007 GMC ENVOY Power seat

Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen
to any of the sources: radio, cassette tapes,
CDs, or DVDs. 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
cassette tapes, CDs, or DVDs through the
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 source. You can operate the rear seat
audio when the main radio is off.
P(Power):Press this button to turn the system
on or off. The rear speakers will be muted
when the power is turned on.
u(Volume):Turn this knob to increase or to
decrease the volume. The left volume knob
controls the left wired headphones and the right
volume knob controls the right wired headphones.
