RP4-GM11
Radio Replacement & Steering Wheel Control Interface
for General Motors Vehicles
Introduction & Features
Important Notes
Wiring Connection Chart
Illustration / Schematic
The RP4-GM11 interface allows the replacement of a factory radio in select General Motors vehicles with Class II radios.
Using this interface will retain factory features such as steering wheel controls (SWC), Warning Chimes, Rear Seat
Controls (RSC, select vehicles) and the BOSE amplier (Standard or Premium) when the original radio is removed. Use
of this interface also allows you to program two radio functions to each SWC button by using short press long press dual
command functionality. The RP4-GM11 also provides data bus driven outputs such as retained accessory power (RAP),
vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
1. The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the
vehicle (see below for setting chart).
2. 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 ash 4 times.
PLEASE NOTE: Due to the many different possible OEM SWC congurations, some applications may need to be reprogrammed for
the SWC assignments to make sense.
3. RSC buttons that are identical to the SWC will mimic the SWC one for one.
4. To prevent over driven audio when installing into a vehicle with a Bose system and the aftermarket radio does not have low level outputs
then an LOC (part # SNI-35 or OEM-2) is recommended to match the input voltage or you can create an audio attenuation circuit (see diagram
2 below for audio attenuation wiring).
5. To prevent ground loop or engine noise when installing aftermarket radios that use a common ground on the outer shield of the low level
outputs will require a ground loop isolator (part # SNI-1)
6. The LED will ash whenever a SWC button is pressed.

Installation Steps
1.The radio select rotary switch on the side of the interface must be adjusted to the proper radio
setting before plugging the interface into the vehicle.
2. Make all connections as described in the chart on page 1. If there is a Bose® Audio system present: Connect the RCA inputs to the
aftermarket radios pre-amp output. The audio level will vary depending on the new radios pre-amp output voltage (2-4 volts is recommended).
If there is not a Bose® Audio system present: Cut the RCA inputs off and connect the aftermarket radios speaker outputs to the remaining
wire according to the chart on page 1.
3. Connect the SWC wire according to the chart on page 1 (aftermarket radio MUST support a wired remote input).
4. If you wish to reassign functions to the SWC follow the programming instructions in the next section.
IMPORTANT! The interface comes pre-programmed for the functions listed in the chart below and does not require programming unless you
wish to re-assign the SWC functions to different buttons. The SWC can always be restored to default settings by pressing the program button
on the side of the interface once and waiting for the timeout. PLEASE NOTE: Due to the many different possible OEM SWC congurations,
some applications may need to be reprogrammed for the SWC assignments to make sense.

Default Steering Wheel Control Programming
If you wish to re-assign the SWC functions or utilize short press long press dual command functionality, the interface must be
programmed in the specic order shown on 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 ash off and on conrming 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.

Testing & Verication
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 amplied Systems will not fade as neither the
aftermarket radio or the RP interface have the ability to control the amplier’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 ash 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
