BEFORE ATTEMPTING ANY INSTALLATION
The GMOS-LAN-01 is
designed to retain Onstar and retain the warning
chimes that are normally lost when the OEM radio is removed. It
also provides a 12 volt accessory output or proper a termarket
radio operation. THE GMOS-LAN-01 also PROVIDES a MUTE,
PARKING BRAKE, VSS OR SPEED SENSE, AND A REVERSE OUT-
PUT TO MAKE INSTALLING AN AFTERMARKET NAVIGATIONAL
RADIO SIMPLER AND LESS TIME CONSUMING.

7. Cut the gray wire about half way between the two plugs. Connect the gray wire from the 24 pin plug to ampli-
fier’s right front positive speaker output wire. Connect the gray wire from the 12 pin plug to the positive
speakerwire of the Metra SP-2003 or equivalent.
8. Cut the gray/black wire about half way between the two plugs. Connect the gray/black wire from the 24 pin
plug to amplifier’s right front negative speaker output wire. Connect the gray/black wire from the 12 pin plug
to the negative speaker wire of the Metra SP-2003 or equivalent.
Note: I only one SP-2003 is used tape up the gray wires that would normally connect to the second
SP-2003 to avoid a short circuit.
CONNEC IONS O BE MADE ON HE 12 PIN HARNESS:
1. Connect the yellow wire to the radio’s 12 volt battery or memory wire.
2. Connect the black wire to the radio’s ground wire.
3. The black/yellow and black/white wire is for the Onstar volume adjustment. This will be discussed in the
Onstar and Chime Level Adjustment section of this instruction.
When completed, plug the 12 pin harness into the GMOS-LAN-01.
FINAL WIRING CONNEC IONS
Make wiring connections using the EIA color code chart shown below and the
instructions included with the head unit. Metra recommends making connec-
tions as shown below; Strip, Splice, Solder, Tape. Isolate and individually tape
off ends of any unused wires to prevent electrical short circuit.

CHIME VOLUME ADJUS MEN
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.
ONS AR LEVEL ADJUS MEN
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 URN 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.
Now when the turn signal is on, the relay will make the audible “clicking” noise.
INS ALLING HE GMOS-LAN-01
1. With all connections completed, plug the 14 and 12 pin harnesses into the GMOS-LA -01.
2. Reconnect the negative battery terminal.
3. Plug the 30 pin GM harness into the vehicle side harness, and plug the aftermarket radio harness into the
aftermarket radio.
4. Cycle the key by turning the ignition on then back off, then back on again to test the radio.
ES ING HE GMOS-LAN-01
1. Turn the ignition on, and then turn the aftermarket radio on.
2. Push the Onstar button, the radio should turn off and you should hear Onstar. Push the Onstar cancel button
and the radio should come back on.
