  • Connect the White wire to the left front positive speaker output.

  • Connect the White/Black wire to the left front negative speaker output.

  • If the aftermarket radio has a mute wire, connect the Brown wire to it. If the mute wire is not connected, the radio will turn off when OnStar is activated.

The following (3) wires are for multimedia/navigation radios that require these wires.

  • Connect the Light Green wire to the parking brake wire.
  • Connect the Blue/Pink wire to the speed sense wire.
  • Connect the Green/Purple wire to the reverse wire.

From the AXGMLN-09 harness to the aftermarket radio:

  • Connect the Red and White RCA jacks to the audio AUX-IN jacks of the aftermarket radio.

  • Connect the Yellow RCA jack to the backup camera input jack.
    Note: Only connect this jack if the RPO code I03 is present in the “Service Parts Identification” sticker located inside the glove box. If this code is not present, use the AXBUCH-GM3 harness (sold separately) to retain the factory backup camera.

  • Disregard the DIN jack, it will not be used in this application.
    Note: The relay attached to the AXGMLN-09 harness is only for audible turn signal clicks. No extra steps are required to retain this feature, so leave the relay as-is.

INSTALLATION

With the key in the off position:

  1. Connect the 16-pin harness with stripped leads, and the AXGMLN-09 harness, into the AXGMLN-09 interface.
  2. If an AXSWC (sold separately) will be used, do not connect it until the AXGMLN-09 is programmed and fully functional.
    Attention! Do not connect the AXGMLN-09 harness to the wiring harness in the vehicle just yet.

PROGRAMMING

For the steps below, the L.E.D. located inside the AXGMLN-09 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 AXGMLN-09 harness to the wiring harness in the vehicle. The L.E.D. will initially be Green to indicate the interface is powered.
    Note: For the Equinox and Malibu, use part number AXEXH-GM09 (sold separately) to extend the wiring harness to the right of the glovebox where the radio brain is located at.

  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. Note: The vehicle must be running for the factory camera to power on.

  6. If the interface fails to function, refer to the Troubleshooting section.

ADJUSTMENTS

Chime Level Adjustment

  1. With the vehicle on, turn it off and leave the key in the ignition. Open the driver’s door; chimes will be heard.

  2. Wait 10 seconds, and then with a small flat-blade screwdriver, turn 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.

  3. When the chime level is at a desired level, remove the key from the ignition. This will lock the chime volume at its current level.

OnStar Level Adjustment

  1. Press the OnStar button to activate it.
  2. While OnStar is speaking, press the VOLUME UP or VOLUME DOWN buttons on the steering wheel to raise or lower the OnStar level.
  3. If the vehicle does not come equipped with steering wheel controls, find the Black/Yellow wire on the AXGMLN-09 harness. While
  4. 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.
