Optional Steering Wheel Control Programming (cont.)
The Mute and Source buttons long press commands can be set to control the factory OnStar / XM functions or given the ability
to control the aftermarket radio. This option can be set using the program button on the side of the interface. The default setting
for these buttons is factory mode which controls the factory OnStar and XM tuner. If these buttons are set to aftermarket mode,
OnStar must be accessed by using the factory controls located on the rearview mirror, and the factory XM tuner can no longer be
accessed.
Aftermarket Mode
• OnStar control through the SWC Mute button is disabled.
This will free up the Mute button to send mute radio
command and a second function.
• In order to program the Source button for short press / long
press in vehicles with external XM tuner, you must unplug
the XM tuner.
Factory Mode
• The SWC Mute and Source buttons are programmed
to control OnStar and Factory XM. They cannot be
programmed for short press / long press dual command
functionality and are blocked from doing so.
• Preset right button can be programmed for dual commands.
However, when XM Control is on, radio commands are
disabled temporarily. The Preset right button will control
XM preset up.
• When XM control is off the Preset right button will send
radio commands as normal.
Use the function chart on the next page as a guide to program the functions in the proper order for your new radio

2. Press and release the programming button on the side of the interface the number of times that corresponds with either
factory or aftermarket mode. One press will set factory mode and two presses will set aftermarket mode. The LED will blink
each time the button is pressed.
3. Once you have chosen either factory or aftermarket mode, after 2.5 seconds the LED will come on solid.
At this point you
have two options:
A. To restore the SWC to factory default settings:
Simply wait 7 seconds and the LED will blink 3 times indicating
the interface has timed out. The default settings are now restored and no further action is required.
B. To program custom SWC assignments:
Proceed to step 4
4.
With the LED on, press the first button to be learned on the steering wheel, the LED will turn off.

Release the button within 1.5 seconds. The LED will turn back on.
B. For long press functionality:
Hold the button until the LED starts blinking. Release the button and the LED
will go back to solid.
5. If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.
6.
If you come across a function in the chart that your steering wheel does not have, or you do not want to program, press and
release the program button on the side of the interface to skip that function.
7.
Once programming is completed, wait seven seconds. The LED will flash three times indicating end of programming.
8. Test the interface for proper functionality. Whenever a SWC is pressed the LED on the interface should blink. If any function
does not work, repeat the programming steps.
