-FM to return to the radio when a

This feature allows rear seat passengers to listen to and
control any of the music sources, including AM
-FM,
cassette tapes and CDs, through the Rear Seat Audio
(RSA) controller. 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 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. Be aware that
the front seat audio controls always have priority over
the RSA controls. 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.
This feature is intended for rear seat passengers.
