Vehicles with this feature allow the rear seat passengers to listen to and control any of the music sources: radio, CD, DVD, or other auxiliary sources. The rear seat passengers can control the same music sources the front seat passengers are listening to (dual control) or a different source. For example, rear seat passengers can listen to and control 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 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 band on the other system.

RSA functions can be operated even when the main radio 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.

The audio system allows the rear speakers to continue playing even 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 auxiliary input (if available), located below the RSA.

Turn the iPod on, then choose the auxiliary input with the RSA SRCE button. An iPod® or portable audio device can be connected to the front auxiliary jack or the USB port.

Volume: Turn this knob to increase or to decrease the volume of the wired headphones. 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, USB, auxiliary jack, and rear auxiliary.

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.

Press the left seek arrow to go back to the start of the current track or chapter (if more than ten seconds have played). This function is inactive, with some radios, if the front seat passengers are listening to the disc.
