Default Steering Wheel Control Programming
IMPORTANT!
The interface comes pre-programmed for all of the vehicles factory SWC functions and does not require
programming unless you wish to re-assign the SWC functions or utilize short press long press dual command functionality. The
SWC can always be restored to default settings by pressing and releasing the program button on the side of the interface once
and waiting 7 seconds for the LED to flash 3 times.
Optional Steering Wheel Control Programming
If you wish to re-assign the SWC functions, utilize short press long press dual command functionality, the interface must be
programmed in the specific order shown in the chart on page 4. 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 programming button on the side of the interface to
skip that function. The LED will flash off and on confirming that you have successfully skipped that function and are ready to
proceed to the next one.
Short Press Long Press Dual Command Functionality
This feature allows you to assign two aftermarket radio functions to each of the vehicles SWC buttons. It can be used with as
many of the buttons as the user likes or none at all. When this functionality is implemented, quickly pressing and releasing a
SWC button will initiate the short press command while pressing and holding a SWC button for longer than two seconds will
initiate the long press command. Please note that no long press commands are programmed by default. If you wish to assign
dual command functionality to the SWC please follow the programming steps on the next page.
