Circuit Description
The rear seat audio (RSA) allows rear seat passengers to listen to and control any of the music sources: radio, CDs, DVDs, or other auxiliary sources. The rear seat passengers can only control the music sources the front seat passengers are not listening
to. The sourced audio can be heard through wired headphones plugged into the jacks on the RSA. The RSA receives audio signals from the radio rear audio output circuits.
