Installation Guide

AXGMLN-02

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
