With the key in the off position:
• Connect the 16-pin harness with stripped leads, and the AXGM-05 harness, into the interface.
• Connect the AXGM-05 harness to the wiring harness in the vehicle.
Attention! If the interface loses power for any reason, the following steps will need to be performed
again. Also, if installing an ASWC-1 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, and then to the accessory position. Test all functions of the
installation for proper operation, before reassembling the dash.
Chime level adjustment:
• Turn the vehicle off but leave the keys in the ignition. Open the driver’s door and leave it
open; chimes will be heard.
• Wait 10 seconds, and then with a small flat-blade screwdriver, adjust 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.
• When the chime is at the desired level, remove the keys from the ignition. This will lock
the chime level in at its current level.
OnStar level adjustment:
• Press the OnStar button to activate it.
• While OnStar is speaking, press the VOLUME UP or VOLUME DOWN buttons 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 AXGM-05 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.
