Vehicles with this feature allow the 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 control the same music sources the front seat passengers are listening to (dual control, is available depending upon radio) or a different source. For example, rear seat passengers can control and listen to a CD through the headphones, while the driver listens to the radio through the speakers. The rear seat passengers have control of the volume for each set of headphones.

The RSA can be used even when the main radio is off. The front audio system will display the headphone icon when the RSA is on, and will disappear from the display when it is off.

Audio can be heard through wired headphones (not included) plugged into the jacks on the RSA. If the vehicle has this feature, audio can also be heard on Channel 2 of the wireless headphones.

To listen to an iPod or portable audio device through the RSA, attach the iPod or portable audio device to the front auxiliary input (if available), located on the front audio system. Turn the iPod on, then choose the front auxiliary input with the RSA SRCE button.

(Power): Press this button to turn the RSA on or off.

Volume: Turn this knob to increase or to decrease the volume. The left knob controls the left headphones and the right knob controls the right headphones.

SRCE (Source): Press this button to switch between the radio (AM/FM), XM™ (if equipped), CD, and if the vehicle has these features, DVD, front auxiliary, and rear auxiliary.

  (Seek): When listening to FM, AM, or XM™ (if equipped), press either seek arrow to go to the previous or to the next station or channels and stay there. This function is inactive, with some radios, if the front seat passengers are listening to the radio. Press and hold either seek arrow until the display flashes, to tune to an individual station. The display stops flashing after the buttons have not been pushed for more than two seconds. This function is inactive, with some radios, if the front seat passengers are listening to the radio. While listening to a disc, press the left seek arrow to go back to the start of the current track or chapter (if more than ten seconds have played). Press the right seek arrow to go to the next track or chapter on the disc. This function is inactive, with some radios, if the front seat passengers are listening to the disc.
