To adjust the OnStar volume level find the Black/Yellow wire on the 16-pin

Once the volume is set it will stay at that volume until the Black/Yellow wire is
tapped to ground again. This can be set during 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.
