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 specific order shown in the chart below. 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 below.

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 12 for more details on how to use the app to set this feature.

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 green 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 green.

1. If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.
2. 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.
3. Once programming is completed, wait seven seconds. The LED will flash three times indicating end of programming.
4. 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.

Testing and Verification

1. Turn the ignition on. The LED on the interface will turn on and the +12v accessory wire will turn on.
2. Turn on the radio and check balance and fade.
3. Verify that all SWC are functioning properly.
4. Verify that the programmable 12v+ output is functioning as intended (if connected).
5. Verify that all HVAC controls are functioning properly. If the A/C is not blowing cold air, please ensure that the ribbon cables you installed are seated in their connectors properly. Once that is done you may have to drive the vehicle around with the A/C on for up to 20 minutes in order to re-initialize it.
6. The LED & radio will turn off when the ignition is turned off.

Camera Control

1. If you have the VS41 connected, the cameras can be accessed at any time by using the four buttons you relocated from the factory dash panel. See below for button assignments.
2. If the vehicle is equipped with a factory reverse camera, you can use the first button in the bank of four, or the "Mode" button on the SWC, to switch between wide and narrow view, whenever the vehicle is in reverse. PLEASE NOTE: The wide / narrow switch does not function if the reverse camera has been forced. The vehicle must actually be in reverse for this to function.
3. The default operation of additional cameras is: Blind Spot = on when vehicle moving and turn signal on, Front = Manual Only (using push buttons on HVAC panel). Behavior of these cameras can be changed using the RadioPRO PC application (see next section).
