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, utilize short press long press dual command functionality or assign 
the programmable 12v output to a SWC button. 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 ash 3 times.
Optional Steering Wheel Control Programming
If you wish to re-assign the SWC functions, utilize short press long press dual command functionality or assign the programmable 
12v output to a SWC button, the interface must be programmed in the specic 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  ash off and on conrming 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.
Programmable 12v Output
The red/white wire on the interface can be programmed via the RadioPRO app to do a pulsed or latched 12v output which can 
then be assigned to any of the vehicle’s factory SWC buttons. When assigned, the factory SWC button will activate the pulsed or 
latched output to control external accessories. Please refer to page 6 for more details on how to use the app to set this feature.
