Testing & Verification

Product Updates (Firmware)

1. Vehicles equipped with a DVD player built into the rear screen assembly:

  The RP4-GM11 will allow the VES DVD player and rear screen to function as if the factory radio were present. A/V will be passed 

  from the factory DVD player to the rear screen and audio can be heard through the headphones. A/V cannot be passed from the 

   factory DVD player to the aftermarket head unit.

The RP4-GM11 can be updated with new firmware as it becomes available using the PAC-UP interface updater (sold separately). 

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. Note: 

Premium Factory amplified Systems

 will not fade as neither the

aftermarket radio or the RP interface have the ability to control the amplifier’s fader.

3.

Verify that the factory subwoofer (if present) is playing

4. Verify that all SWC are functioning properly.

4. Turn off vehicle & remove key. RAP will be active & keep the radio on for 10 minutes or until the drivers door is opened.

5. The LED & radio will turn off when RAP turns off or the drivers door is opened.

Programming

1.

Turn the key to the ignition position.

2.

Press and release programming button on the side of the interface.

3.

Within 7 seconds, press the button that is to be learned on the steering wheel. The LED will turn off 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 flash 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
