For 1990-2009 cars only

If your vehicle has rear seat audio (RSA), this feature allows rear seat passengers to listen to and control any of the following audio sources: AM/FM tuner, front CD player, and XM™ Satellite Radio Service (if equipped). However, the rear seat passengers can only control the sources that the front seat passengers are not listening to. For example, rear seat passengers may listen to a CD in the front radio and control it 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 have priority over the RSA controls. If the front seat passengers switch the source for the main radio to a remote source, the RSA will not be able to control the remote source. You can operate the RSA when the main radio is off.

The DVD or auxiliary device will always be available on channel (CHA or CH1) of the wireless headphones. All other RSA sources are available on CHB or CH2 of the wireless headphones, as well as the wired headphones. If the RSA is off, the wired headphones will provide DVD or auxiliary device audio. The rear seat passengers will not be able to listen to XM, on CHB or CH2, if the front passenger is listening to a DVD or auxiliary device.

The remote control will not operate any of the RSA features.
