REV. 7/3/2018 INSTGMOS-LAN-06
With the key in the off position:
• Connect the 16-pin harness with stripped leads, and the GMOS-LAN-06 harness, into the
interface.
Attention! Do not connect the GMOS-LAN-06 harness to the wiring harness in the vehicle just yet.
For the steps below, the L.E.D. located inside the interface can only be seen while active. The
interface does not need to be opened to see the L.E.D.
1. Start the vehicle.
2. Connect the GMOS-LAN-06 harness to the wiring harness in the vehicle. The L.E.D. will initially be
Green to indicate the interface is powered.
3. After a few seconds the L.E.D. will turn on solid Red while the interface automatically programs
to the vehicle. The radio will shut off at this point. This process should take 5 to 30 seconds.
4. After the interface is programmed, the L.E.D. will turn on solid Green, and the radio will come
back on, indicating programming was successful.
5. Test all functions of the installation for proper operation, before reassembling the dash.
6. If the interface fails to function, refer to “Troubleshooting”.
Resetting the Axxess interface
1. The Blue reset button is located inside the Axxess interface, between the two connectors.
The button is accessible outside the Axxess interface, no need to open the Axxess interface.
2. Press and hold the reset button for two seconds, then let go to reset the Axxess interface.
3. Refer to “Programming the Axxess Interface” from this point.
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 volume setting.
• Once the volume is set it will stay at that volume until the Black/Yellow wire is tapped to
ground again.
