Rear Seat Audio (RSA)
If your vehicle has rear seat audio (RSA), this feature
allows rear seat passengers to listen to and control any
of the following audio sources: AM/FM tuner, front
CD player, and XM™ Satellite Radio Service
(if equipped). 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 a CD in the front radio and control it
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.
The DVD or auxiliary device will always be available on
channel (CHA or CH1) of the wireless headphones.
All other RSA sources are available on CHB or CH2 of
the wireless headphones, as well as the wired
headphones. If the RSA is off, the wired headphones
will provide DVD or auxiliary device audio. The rear seat
passengers will not be able to listen to XM, on CHB
or CH2, if the front passenger is listening to a DVD or
auxiliary device.
The remote control will not operate any of the RSA
features.
O (Power): Press this button to turn the RSA system
on or off. RSA CHB or RSA CH2 will appear on the
display when the system is on to indicate the channel to
receive audio for the wireless headphones. Pressing
this button will also silence the rear speakers.
BAND: Press this button to switch between FM1, FM2,
AM, or XM1 or XM2 (if equipped). The selected radio
station will appear on the display. If the front passengers
are listening to the radio, the RSA will not switch
between the bands and cannot change the station.
