To adjust the OnStar volume level find the Black/Yellow wire on the 16-pin harness. Push the Blue
OnStar button, while the voice is speaking tap the Black/Yellow wire to ground.
There are 4 volume settings for OnStar; once the 4th setting is reached and the Black/Yellow wire

installation and then left alone. If user adjustment is desired, the customer may also tap volume "up"
or "down" on the steering wheel (if equipped) to adjust the OnStar level.
