PROGRAMMING THE AXDIS-GMLN11
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 AXGMLAN11-SWC harness to the wiring harness in the vehicle.
3. The L.E.D. will initially turn on solid Green, then turn off for a few seconds while it auto
detects the radio installed.
4. The L.E.D. will then flash Red up to (18) times indicating which radio is connected to the
interface, and then turn off for a couple of seconds. Pay close attention to how many Red
flashes there are. This will help in troubleshooting, if need be. Refer to the L.E.D. feedback
section for more information.
5. After a couple seconds the L.E.D. will turn on solid Red while the interface auto detects the
vehicle. The radio will shut off at this point. This process should take 5 to 30 seconds.
6. Once the vehicle has been auto detected by the interface, the L.E.D. will turn on solid Green,
and the radio will come back on, indicating programming was successful.
7. Immediately after the radio comes back on, the following buttons on the steering wheel
must be pressed in the exact sequence as shown. For each button press, the L.E.D. will turn
on momentarily. If a button is not present, press Volume Up to skip that button.
• Volume Up
• Seek Up
• Volume Up
• PTT (OnStar) or MUTE
• Volume Up

8. The L.E.D. will turn on after the last Volume Up button has been pressed, indicating
programming has ended.
9. Test all functions of the installation for proper operation, before reassembling the dash.
10. If the interface fails to function, refer to Resetting the AXDIS-GMLN11, then resume from step 7.
Notes:
• PTT (OnStar) when pressed will Mute/Attenuate the radio.
• PTT (OnStar) when pressed and held for 2 seconds will activate OnStar, if applicable.
Note: The L.E.D. will turn on solid Green for a moment, and then turn off under normal operation
after the key has been cycled.
ADJUSTING THE AXDIS-GMLN11
OnStar Level Adjustment
• Press the OnStar button to activate it.
• While OnStar is speaking, press the VOLUME UP or VOLUME DOWN button 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 AXDIS-GMLN11 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.
