Rear Seat Audio (RSA) (if equipped)
The rear seat audio (RSA) feature allows rear seat passengers to listen to a different audio program than the front seat passengers. When RSA is ON, the rear vehicle speakers are muted, and the rear passengers can select their own audio program to listen to using the headphones.
The rear seat passengers can only control the sources that are not being listened by the front seat passengers. For example, rear seat passengers can listen to and control CDs or DVDs through the headphones while the driver listens to the radio through the front speakers. 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 is not able to control the source. The rear seat audio can be operated while the main radio is OFF, and the key is RUN, ACCESSORY, or when retained accessory power is active. The rear seat passengers have control of the volume for each set of individual headphones.
Depending on the audio system, the rear speakers may continue to play when the RSA is active through the headphones.
The RSA is integrated into the rear HVAC control module. Audio, video source are controlled by the radio through serial data communication. Some sources are: Radio, CD, and if the vehicle has these features, DVD, front auxiliary, and rear auxiliary.
The rear speaker channels pass through the RSA. The rear seat audio can be muted by the RSA when in use.
