Installing the GMOS-LAN-03
Initializing the GMOS-LAN-03
With the key in the off position:
• Connect the 16-pin harness with stripped leads, and the GMOS-LAN-03
harness, into the interface.
• Connect the GMOS-LAN-03 harness to the wiring harness in the vehicle.
• If using the ASWC-1, connect it after you initialize and test the GMOS-LAN-03,
with the key in the off position.
Attention! If the interface loses power for any reason, the following steps will need
to be performed again. Also, if installing an ASWC-1 connect it after you initialize
and test the interface/radio, with the key in the off position.
• Turn the key (or push-to-start button) to the ignition position and wait until the
radio comes on.
Note: If the radio does not come on within 60 seconds, turn the key to the
off position, disconnect the interface, check all connections, reconnect the
interface, and then try again.
• Turn the key to the off position, and then to the accessory position. Test all
functions of the installation for proper operation, before reassembling the dash.

Adjusting the GMOS-LAN-03
Chime level adjustment:
• Turn the vehicle off but leave the keys in the ignition. Open the driver’s door and leave it open;
chimes will be heard.
• Wait 10 seconds, and then with a small flat-blade screwdriver, adjust the potentiometer clockwise
to raise the chime level; counterclockwise to lower the chime level.
Note: The potentiometer is located on the side of the interface where the 16-pin harness with
stripped leads is connected to.
• When the chime is at the desired level, remove the keys from the ignition. This will lock the chime
level in at its current level.
OnStar level adjustment:
• Press the OnStar button to activate it.
• While OnStar is speaking, press the VOLUME UP or VOLUME DOWN buttons on the steering wheel
to raise or lower the OnStar level.
• If the vehicle does not come equipped with steering wheel controls, locate the Black/Yellow wire
on the GMOS-LAN-03 harness.
• While OnStar is speaking, tap the Black/Yellow wire to ground. Once the OnStar level is set, it will
stay at that level until the Black/Yellow wire is tapped to ground again.
