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.

Optional SWC Programming Procedure

Turn the key to the ignition position.
Press and release programming button on the side of the interface. The Status LED will turn green.
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.
If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.
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.
Once programming is completed, wait seven seconds. The LED will flash three times indicating end of programming.
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.

SWC Re-Calibration Procedure

Turn the key to the ignition position.
Press and hold the programming button until the LED begins blinking amber. When the LED begins blinking, release the programming button. The LED will light solid amber.
Within 7 seconds, press and hold the button that is to be learned on the steering wheel. The LED will turn off when the button is pressed and begin blinking when the value has been learned. Once the LED begins blinking, release the button. Please Note: the buttons must be calibrated in the order shown in the chart. If you press the wrong button the LED will not respond at all.
If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.
If you come across a function in the chart that your steering wheel does not have, press and release the program button on the side of the interface to skip that function.
Once programming is completed, wait seven seconds. The LED will flash indicating end of programming.
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.

After you have re-calibrated the SWC buttons, the default SWC button assignments will be the same as what is listed in the chart on page 3. If you wish to re-assign button functions you must also go through the programming listed above (Optional SWC Programing Procedure).

Testing and Verification

Turn the ignition on. The LED on the interface will turn on and the +12v accessory wire will turn on.
Turn on the radio and check volume, balance and fade. If you do not hear any audio you may need to cycle the ignition to initialize the factory amplifier.
If the overall volume is too low, use the gain adjustment on the side of the RP4.2 interface to set it to the desired level. The best way to do this is to turn the volume on the radio to 3/4 volume, then turn the gain on the RP4.2 until some distortion is heard, then back it down a little.
If you have a JBL system and there is no audio, please make sure the Blue / White wire in the radio connector is hooked up properly. If there is still no audio, reset the interface according to the procedure in the next section.
If fading is acting inconsistent, please ensure that all speakers are connected to the proper polarity.
Verify that all SWC are functioning properly. If any of the SWC are not functioning properly you may need to reset the interface or follow the re-calibration procedure above.
The LED and 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. Please note, the LED will go through two stages before it starts blinking red. First it will blink green, then amber, then red.
This reset will restore the following settings to their factory defaults:

SWC Mapping
Factory Amplifier Settings
Real Time Fade will be reset to on

Introduction & Features

The RPA-VA1 is a differential to single ended video converter. It is designed for use when installing an aftermarket radio into a vehicle that uses a differential camera. The RPA-VA1 can also be used as a video noise filter in cases where the camera ground is on a different plane than the aftermarket radio, by eliminating the ground loop and fixing distortion such as horizontal lines in the video.

Important Notes

It is very important that you connect the RPA-VA1 ground wire to the aftermarket radio’s ground wire. These two components sharing the same ground is critical to the noise filter feature.
The video input connector has 2 independent wires for when you are connecting to a factory reverse camera. The RCA end can be cut off and the harness wires connected directly to the vehicle.
