PAC RP3-GM11 is a radio replacement interface designed for select General Motors vehicles. It allows you to replace the factory radio with a Class II aftermarket radio while retaining essential factory features like warning chimes, BOSE amplifier, and more. Here are some key capabilities of the RP3-GM11:
- Retains factory features such as warning chimes and BOSE amplifier
- Provides data bus driven outputs like retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake
- Offers a secondary output for adding an optional PAC Steering Wheel Control (SWC) retention interface, which also supports Rear Seat Controls (RSC) if equipped

Introduction & Features
Important Notes
Wiring Connection Chart
Illustration / Schematic
The RP3-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 Warning Chimes and BOSE® amplifi er (Standard or Premium) when the original
radio is removed. The RP3-GM11 provides data bus driven outputs such as retained accessory power (RAP), vehicle speed
sensor (VSS), illumination, reverse trigger and parking brake. The RP3-GM11 also provides a secondary output for adding an
optional PAC Steering Wheel Control (SWC) retention interface (SWI-RC, SWI-PS, SWI-JACK, SWI-ECL2 or SWI-X). Rear Seat
Controls (RSC) if equipped will also be retained with the SWI interface.
1. When used in Non-BOSE® applications simply cut off the RCA connectors and connect the remaining wires to the aftermarket
radios high level speaker outputs.
2. For BOSE® systems, the recommended line level input is between 2-4 volts from the aftermarket radio.
3. RSC buttons that are identical to the SWC will mimic the SWC one for one
4. To prevent over driven audio when installing the interface into a vehicle with a BOSE® system, and the aftermarket radio does
not have low level outputs, then an LOC (part # SOEM-4 or LP3-4) is recommended to match the input voltage or you can create
an audio attenuation circuit (see diagram 2 below for audio attenuation wiring).
5. Use the 4 position selector switch located on the side of the interface to select the best chime output volume for your specifi c
installation .

Testing & Verifi cation
Product Updates (Firmware)
Installation Steps
1. It is extremely important to makes sure the ignition is off and the drivers door open before connecting the interface to 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 the vehicle is not equipped with the BOSE® Audio system: Cut the RCA inputs off and connect the
aftermarket radios speaker outputs to the remaining wire according to the chart on page 1.
1. The RP3 provides a SWC output connector attached
to the harness. For ease of installation, all necessary
connections for an SWI have been made for you.
2. When using this SWC output connector the SWC
interface MUST BE PROGRAMMED FOR VERSION 2.
(refer to SWC interface programming instructions for
exact programming sequence).
3. Both loops should remain in tact.
4. During steering wheel button assignment programming
the vehicle should be running and each button should
be pressed and held for at least 5 seconds. Please refer
to the SWI manual for button assignment order.
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 amplifi ed Systems will not fade as neither the
aftermarket radio or the RP interface have the ability to control the amplifi er’s fader.
3. Verify that the factory subwoofer (if present) is playing
4. If an optional SWC retention interface was used, verify that all SWC are functioning properly.
5. Turn off vehicle & remove key. RAP will be active & keep the radio on for 10 minutes or until the drivers door is opened.
6. The LED & radio will turn off when RAP turns off or the drivers door is opened.
7. Use the 4 position selector switch located on the side of the interface to select the best chime output volume for your specifi c
installation. Setting 1 being loudest and 4 softest.
The RP3-GM11 can be updated with new fi rmware as it becomes available using the PAC-UP interface updater (sold separately).
