Testing & Verication
1. Turn the ignition on. The LED on the interface will turn on & the +12v accessory wire will turn on.
2. Turn on the radio & check balance & fade. (Premium systems may not fade.)
3. Verify that all SWC are functioning properly. The LED will ash whenever a SWC button is pressed, even if a function is not
assigned to the button.

5. The LED & radio will turn off when the ignition is turned off.
Restoring Factory Settings
You can restore the interface to factory default settings by pressing and holding the programming button on the side of the module
until the status LED starts blinking red. Once the LED starts blinking red, release the button. You must release the button while
the LED is blinking red in order to perform the reset.
This reset will restore the following settings to their factory defaults:
• SWC Mapping
• Programmable 12v+ Output (Latched)
• Parking Brake Output Settings
• Factory Warning Chime Volume (High)
Optional SWC Programming Procedure
1. Turn the key to the ignition position.
2. Press and release programming button on the side of the interface. The Status LED will turn green.
3. Within 7 seconds, press the button that is to be learned on the steering wheel. The LED will turn red when the button is pressed.
At this point you have two options:
A. For short press functionality: 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.
4. If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.
5. 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.
6. Once programming is completed, wait seven seconds. The LED will ash three times indicating end of programming.
7. 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
