Rear Seat Audio (RSA): Notes
WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
The rear seat audio (RSA) and rear HVAC control functions are combined into one dual function control unit. The rear seat audio (RSA) control allows the rear seat passengers to listen to a different music source than the front seat passengers. The rear seat passengers can only control the music sources that the front seat passengers are not listening to. 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.
