Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the audio sources: radio, cassette tapes, CDs,
DVDs, XM (if your vehicle is equipped with XMTM
Satellite Radio Service), or DAB (if your vehicle is
equipped with DAB) depending on your vehicles options.
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. The front seat audio controls
always override the RSA controls.
