Testing the GMOS-LAN-03
1) Turn the ignition on if not already, and then turn the radio on to verify that the radio
works. Check balance and fader controls for proper operation.
2) Push the OnStar button (if equipped) to verify OnStar is working. The radio will shut off or
mute, depending if the Brown wire on the 16-pin harness is connected, and OnStar will
be heard through the front speakers. Turn off OnStar and the radio will turn back on.
Chime Volume Adjustment
To adjust the chime volume, use a small
screwdriver to rotate the potentiometer
clockwise to make the chime louder and
counterclockwise to make it softer. The
potentiometer is located on 16-pin side
of the GMOS-LAN-03.
OnStar Level Adjustment
To adjust the OnStar volume level find the
Black/Yellow wire on the 14-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.
Additional 12-pin harness (ASWC harness)
This 12-pin harness is to be used in conjunction with the ASWC (not included).
Please refer to ASWC instructions for programming.
