Installing the AXGMLN-02
With the key in the off position:
• Connect the 16-pin harness with stripped leads, and the AXGMLN-02 harness,
into the interface.
• Connect the AXGMLN-02 harness to the wiring harness in the vehicle.
• If applicable, connect the backup camera harness to the wiring harness in the vehicle .
Note: If using the AXSWC, connect it after you initialize and test the
AXGMLN-02, with the key in the off position.
Initializing the AXGMLN-02
Attention! If the interface loses power for any reason, the following steps will need
to be performed again. Also, if installing an AXSWC, 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, pause for a moment, and then to the accessory
position. Test all functions of the installation for proper operation, before
reassembling the dash.

Adjusting the AXGMLN-02
Audio level adjustment:
• With the vehicle and radio turned on, turn the volume up 3/4 of the way.
• With a small flat-blade screwdriver, adjust the potentiometer clockwise to
raise the audio level; counterclockwise to lower the audio level.
• Once at a desired level, audio level adjustment is complete.
Chime level adjustment (for models without a digital amplifier *):
• With the vehicle on, turn it off and leave the keys in ignition. Open the driver's
door; chimes will be heard.
• Wait 10 seconds, and then with a small screwdriver, turn the potentiometer
clockwise to raise the chime level; counterclockwise to lower the chime level.
• When the chime is at a desired level, remove the keys from the ignition. This
will lock the chime volume at its current level.
* Please reference the "Service Parts Identification" sticker located in the glove box
for the RPO code STZ or Y91. If STZ or Y91 are present, then the vehicle is equipped
with a digital amplifier. Refer to the vehicle owner's manual to adjust the chimes
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, or they no
longer function, locate the Black/Yellow wire on the AXGMLN-02 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
