Introduction and Features
Important Notes
1. Aftermarket radio must have an auxiliary input in order to retain RSE audio.
2. Aftermarket radios with a 2-wire resistive based SWC circuit will not have default button assignments programmed. Please
refer to the owners manual of the radio you are installing to nd out the proper SWC programming procedure.
3. If the vehicle chimes when the radio is removed, the CMX is not necessary. In order to get the best possible sound out of the
CMX, please mount it in a place free and clear of any obstructions, preferably as close as possible to the bottom of the dash
pointing down toward the oor of the vehicle.
4. The external speaker, part number (RP-SPX, Sold Seperatly) must be used when installing a 4 channel amplier to retain the
OnStar prompts. It can be purchased through any PAC authorized dealers if required for your installation.

Using this interface will retain factory features such as Warning Chimes, Bose Amplier, Steering Wheel Controls (SWC), Rear
Seat Entertainment (RSE), and Rear Seat Controls (RSC) when the original radio is removed. The RP5-GM11 provides data bus
driven outputs such as retained accessory power (RAP), vehicle speed signal (VSS), illumination, reverse trigger and parking
brake.

Installation Steps
Other = Advent, BOYO, Dual, Lightning Audio, Rockford Fosgate, Visteon
Set DIP switches that correspond with your radio to the ON position.
Set all other DIP switches to the OFF position.
If your brand is not listed above, please use “ALL OTHER BRANDS.”
1. Set the Radio Select DIP switches according to the radio you are installing.
2. Wire your aftermarket radio to the RP5-GM11’s harness according to the wiring connections chart below.
3. The Brown mute loop in Interface Connector 4 (if not cut) will turn the RP5’s accessory output o󰀨 when any OnStar
function is active. If the aftermarket radio has a mute input, cut this loop and connect the Brown wire in pin 23 to it. This pin
is located in the top row next to the solid blue wire. (The top of the connector has the locking tab on it).
4. Plug Interface Connectors 1 and 2 into the appropriate ports on the RP5-GM11 interface (using the diagram on Page 1 or
the label on the bottom of the interface to identify the connector ports).
5. The Connector 3 connection will be dependent upon whether or not the vehicle has a factory amplied system. Plug this
connector into one of the two ports on the RP5-GM11 (using the diagram on Page 1 or the label on the bottom of the interface
to identify the port appropriate for the installation).
6. If the aftermarket radio is equipped with an auxiliary input and you wish to retain the factory RSE audio, plug the RCA
connectors from the Vehicle Connector 2 into the radios auxiliary input.
7. Remove the factory radio and plug in the RP5-GM11’s Vehicle Connector 1 and Vehicle Connector 2 into the factory vehicle
harness.
8. If you wish to reassign functions to the SWC, follow the Optional Steering Wheel Control Programming on Page 4.
9. Plug the 2-Pin connector into the CMX Chime Module (If the vehicle chimes when the radio is removed, the CMX is not
necessary). PLEASE NOTE: In order to get the best possible sound out of the CMX, please mount it in a place free and clear
of any obstructions, preferably as close as possible to the bottom of the dash pointing down toward the oor of the vehicle.

of your choice. Please see the Optional Steering Wheel Control Programming instructions on Page 4 for more details.
B. 2 Chimes and LED 1 ash amber: SWC re-calibration (this mode is available in the Corvette only).This allows you
to re-calibrate the analog SWC in the event they fall out of the expected range and do not function properly. If data
control SWC are detected by the interface, this mode will be automatically skipped.
C. 4 Chimes and LED 1 ash red: Master reset. This does a master reset of the interface and restores the following
settings to factory defaults:

Optional Programming Order
Optional Steering Wheel Control Programming
Programming
1. Turn the key to the ignition position.
2. Press and hold programming button on the side of the interface until LED 1 blinks green then release programming button
and the LED will go solid green.
3. Within 7 seconds, press the button that is to be learned on the steering wheel. LED 1 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. LED 1 will turn back to green.
B. For long press functionality: Hold the button until LED 1 starts blinking. Release the button and the LED will
go back to green.
4. 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. LED 1 will ash three times indicating end of programming.
7. Test the interface for proper functionality. Whenever a SWC is pressed LED 1 will illuminate green.
8. If any function does not work, repeat the programming steps.
Testing and Verication
1. Turn the ignition on. LED 1 will illuminate red and the +12v accessory wire will turn on.
2. Turn on the radio and check chimes, volume, balance, and fader.
3. In vehicles equipped with Premium Bose (Y91 / UQA): If the overall volume is too low, use the adjustment dial on the
side of the 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 adjustment dial on the RP5-GM11 clockwise until some distortion is heard, then counter-clockwise a little.
4. Verify that all SWC buttons are functioning properly for both the aftermarket radio and OnStar. To adjust OnStar volume,
press the OnStar button on the mirror then use the volume buttons on the SWC, or the adjustment dial on the side of the
module to adjust the level. When you hear a chime during this process it means you have reached the farthest minimum /
maximum level.
5. Pressing the OnStar button on the rearview mirror will turn o󰀨 the rear speakers and allow the OnStar audio to be heard in
the two front speakers. The OnStar active LED 2 will also turn on. When
OnStar disconnects, the radio will un-mute or turn back on and the OnStar
LED will turn o󰀨. Pressing the VR / OnStar button on the steering wheel will
also activate OnStar.
6. Turn o󰀨 vehicle and remove key. RAP will be active and keep the radio on
for 10 minutes or until any door is opened.
7. The LED 1 and radio will turn o󰀨 when RAP turns o󰀨 or until any door is
opened.
8. Use the 4-position selector switch located on the side of the CMX chime
module to select the best chime output volume for your specic installation.
Setting 1 being loudest and 4 being softest.

Rear Seat Entertainment (RSE); If equipped
The factory RSE system will function independently from the aftermarket radio. The unit will power up and pass audio through
the headphones as long as the vehicle’s ignition is on. If you wish to pass audio from the RSE to the aftermarket radio you must
connect the RCAs from the 12-pin connector to the aftermarket radios auxiliary input. Select the aftermarket radios auxiliary input
to hear RSE audio.

Please Note: This is only necessary if after installation, the SWC are acting erratic or
unresponsive in the Corvette.
1. Turn the key to the ignition position.
2. Press and hold the programming button until LED 1 blinks amber and you hear two chimes.
When this happens, release the programming button.
3. Within 7 seconds, press and hold the button that is to be learned on the steering wheel. The

5. If you come to a button in the list that your vehicle does not have, skip it by pressing the
programming button on the interface. Any buttons not learned during this process will not
function.
6. Once programming is completed, the LED 1 will ash amber 3 times indicating end of
programming.
7. Test the interface for proper functionality. Whenever a SWC is pressed LED 1 on the interface
should blink green. If any function does not work, repeat the programming steps.
