Installing the BX-GM4

With the key in the off position:
• Connect the 16-pin harness with stripped leads into the interface.
• Connect the BX-GM4 harness into the interface.
• Connect the BX-GM4 harness into the vehicle.
• With all connections completed, reconnect the negative battery terminal.
Note: If retaining steering wheel controls, ensure the jack/wire is connected
before proceeding to the next step.

Initializing the BX-GM4

• Turn the key to ignition, the L.E.D. inside the interface by the 16-pin harness
will turn on solid red.
• After 30 seconds the L.E.D. will turn off for a few seconds, and then flash up
to 15 times depending on what radio it sees connected to it, and then turn off
again. Refer to the L.E.D. feedback section for more information.
Note: If the L.E.D. does not turn off, it is not communicating to the vehicle. Turn
the key off, check all connections, and then try again.
Note: For the vehicles in the application list with a †, the audio controls on
the steering wheel must be programmed to the BX-GM4 in a different manner.
Refer to manual programming mode for instructions to do so.

Adjusting the BX-GM4

Chime level adjustment (digital amplified models only):
• 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.
Audio level adjustment (digital amplified models only):
• With the vehicle and radio turned on, turn the volume up 3/4 of the way.
• With a small screwdriver, adjust the potentiometer clockwise to raise the audio
level; counterclockwise to lower the audio level.
• Once at a desired level, your audio level adjustment is complete.
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, find the
Black/Yellow wire on the 22-pin 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.
