TABLE OF CONTENTS
*Important: Before beginning any of the following, disconnect the negative battery terminal
to prevent an accidental short circuit.
1
INSTALLING THE INTERFACE
From the 20 pin harness:
• Connect the Red wire to the ignition/accessory wire of the aftermarket radio.
• Connect the Orange/White wire to the illumination wire of the aftermarket radio. If the
aftermarket radio has no illumination wire just tape off the Orange/White wire.
• Connect the Blue/White wire to the amp turn on wire of the aftermarket radio.
• Connect the Brown wire to the mute wire of the aftermarket radio. If the aftermarket
radio does not have a Mute wire, tape up the Brown wire.
The Black/Yellow wire will be discussed later on in the instructions
For Non-Amplied Systems:
• Connect the White wire to the left front positive speaker output of the aftermarket radio
• Connect the White/Black wire to the left front negative speaker output of the aftermarket
radio
• Connect the Gray wire to the right front positive speaker output of the aftermarket radio
• Connect the Gray/Black wire to the right front negative speaker output of the
aftermarket radio
For Amplied Systems:
• Connect the White rca to the left front low level output of the aftermarket radio
• Connect the Gray rca to the right front low level output of the aftermarket radio
• Connect the Green rca to the left rear low level output of the aftermarket radio
• Connect the Violet rca to the right rear low level output of the aftermarket radio
The following wires are for the aftermarket radios that have navigation built in:
• Connect the Green wire to the parking brake wire of the aftermarket navigation radio.
• Connect the Blue/Pink wire to the VSS or speed sense wire of the aftermarket naviga-
tion radio.
• Connect the Green/Purple wire to the reverse wire of the aftermarket navigation radio.

POTENTIOMETERS
Chime/Turn signal Volume Adjustment
To adjust the chime volume, use a small screwdriver to rotate the potentiometer, located
on the 8 pin harness side of the interface (closest to 8 pin harness). Turn clockwise to
make the chime/turn signal louder and counterclockwise to make the chime/turn signal
softer. Turn signal will not be affected in non amplied or class II systems.
Overall Gain Level Adjustment
To adjust the overall audio volume of your vehicle, use a small screwdriver to rotate the
potentiometer, located on the 8 pin harness side (furthest away from 8 pin harness). Turn
clockwise to make gain louder and counterclockwise to make the gain softer.
Onstar Level Adjustment
To adjust the Onstar volume level nd the Black/Yellow wire on the 20 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/Yel-
low wire is tapped to ground it will automatically go back to the rst 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.
3
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.
TESTING THE GMOS-100i
Turn the ignition on, and then turn the aftermarket radio on.
Push the Onstar button, the radio should turn off (if mute wire is connected radio will mute)
and you should hear Onstar. Push the Onstar cancel button and the radio should come
back on.
