Buick 2004 Rendezvous - Manual (Page 266)

Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to and
control any of the music sources: radio, cassette tapes,
and CDs. However, the rear seat passengers can only
control the music sources that the front seat passengers
are not listening to. For example, rear seat passengers
may listen to a cassette tape or 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.
Thefront 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
play the same remote source. The rear speakers will be
muted when the RSA power is turned on. You may
operate the RSA functions even when the main radio
is off.
If your vehicle has the rear seat entertainment (RSE)
system and the system is on, the rear seat passengers
can listen to the DVDs through the wired headphone
jacks on the RSA system. The RSE system cannot be
controlled with the RSA system.
