OnStar® (If equipped)

When OnStar® is activated, a serial data message is sent to the radio that activates a software program. When the software begins its process, the fade goes to the front, Bass and Treble are set to the mid range, the outputs are mono and the audio source is OnStar®. OnStar® takes priority over any other audio source. All of these actions are preset values stored in the radio.

For additional OnStar® information, refer to OnStar Description and Operation .
