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. However, the rear seat passengers can only control the music sources the front seat passengers are not listening to (except on some radios where dual control is allowed). For example, rear seat passengers can control and listen to a CD through the headphones, 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 radio functionality is controlled by both the RSA and the front radio.

Only one band can be tuned to at one time. Changing the band on the RSA or the front radio will change the band on the other system, if they are both sourced to the radio.

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

Depending on the audio system, the rear speakers may continue to play when the RSA audio is active through the 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: To increase or decrease headphone volume, turn the knobs located next to the SRCE or PROG buttons. 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 the seek arrows 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 10 seconds have played). Press the right seek arrow to go 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.

While a DVD video menu is being displayed, press either seek arrow to perform a cursor up or down on the menu. Hold either seek arrow to perform a cursor left or right on the menu.

PROG (Program): Press this button to go to the next preset radio station or channel set on the main radio. This function is inactive, with some radios, if the front seat passengers are listening to the radio.

While a CD or DVD-A disc is playing, press this button to go to the beginning of the CD or DVD-A.

This function is inactive, with some radios, if the front seat passengers are listening to the CD or DVD-A.

While a disc is playing in the CD or DVD changer, press this button to select the next disc, if multiple discs are loaded. This function is inactive, with some radios, if the front seat passengers are listening to the disc.
