CHIME VOLUME ADJUSTMENT
To adjust the chime volume, use a small screwdriver to rotate the potentiometer, located on the 14 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 12 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 vol-
ume 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, a momentary contact
switch (sold separately) can be added. Connect one terminal from the switch to ground and the other terminal to the
Black/Yellow
wire. The volume will change one level every time the switch is pressed.
AUDIBLE TURN SIGNAL
When the factory radio is removed the audible turn signal indicator is lost.
If that turn signal “clicking” is desired follow these steps:
1.
Using a SPDT relay (Metra part # E-123), connect pin #85 to the Black/White wire in the 12 pin harness.
2. .
Connect pin #86 to the 12 volt constant wire on the 12 pin harness.
3 .
Be sure to cover the other leads of the relay by either using female spade connectors or using tape to cover
the leads.
N
ow when the turn signal is on, the relay will make the audible “clicking” noise.
