Chime Volume Adjustment
To adjust the chime volume, use a small screwdriver to
rotate the potentiometer, located on the 16 pin harness
side of the interface, clockwise to make the chime
louder and counterclockwise to make the chime softer.
Onstar Level Adjustment
To adjust the Onstar volume level find the Black/Yellow
wire on the 22 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 is tapped to ground it will automatically go back to
the first volume setting. 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.
