Installation; Audio Level Adjustment - Axxess GMOS-MOST-01 Installation Instructions Manual

With the key in the off position:
• Connect the 16-pin harness with stripped leads, and the GMOS-MOST-01 harness into the interface.
• Connect the GMOS-MOST-01 harness to the wiring harness in the vehicle.
• If an ASWC-1 (sold separately) will be used, do not connect it until the GMOS-MOST-01 is programmed and fully functional.
Attention! If the interface loses power for any reason, the following steps will need to be performed again.
• Turn the key (or push-to-start button) to the ignition position and wait until the radio comes on.
Note: If the radio doesn't come on within 60 seconds, turn the key to the off position, disconnect the interface, check all
connections, reconnect the interface, then try again.
• Turn the key to the off position, then to the accessory position. Test all functions of the installation for proper operation, before
reassembling the dash.

AUDIO LEVEL ADJUSTMENT

• With the vehicle and radio turned on, turn the volume up 3/4 of the way.
• Locate the end of the GMOS-MOST-02, where the 16-pin harness with stripped leads connects to.
• 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.
