Rear Seat Audio (RSA): Notes

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The rear seat audio (RSA) control allows the rear seat passengers to listen to a different music source than the front seat passengers. For example, the rear seat passengers may listen to the cassette 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 headphone. The primary radio controls always override the RSA controls.

The remote radio control supply voltage circuit, from the radio, supplies voltage to the RSA control when the radio is ON. When the RSA control is turned ON, a voltage signal is sent back to the radio on the RSA enable circuit. After receiving the voltage signal, the radio is enabled to control RSA audio functions. The radio controls RSA functions through the remote radio control signal (RUI2) circuit, some vehicles may use a class 2 communication circuit. When the radio receives the enable signal the rear speakers are muted. This allows the user to listen to the audio through the headphones.
