Rear Seat Audio (RSA) With Entertainment System

This feature allows rear seat passengers to listen to and control any of the sources: radio and CDs. An audio or radio source can be listened to but cannot be changed from the RSE if the front seat passengers have selected the same source from the front seat controls. (For example, the radio station selected with the front seat controls cannot be changed by the rear seat control(s).

The front seat audio controls always have priority over the RSA controls. If the front seat passengers switch to the same source as the RSA, the RSA no longer controls the source.

You can operate the RSA when the main radio is off.

The rear seat passengers have control of the volume for each set of headphones.
