PAC RP5-GM32 Radio Replacement and Steering Wheel Control Interface

Introduction & Features

The RP5-GM32 interface allows the replacement of a factory radio in select General Motors vehicles with 29-bit LAN radios. Using this interface will retain factory features such as OnStar, steering wheel controls (SWC), warning chimes, you to program two radio functions to each SWC button by using short press long press dual command functionality. The RP5-GM32 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.

Important Notes

1. These instructions only apply to R.2.6.6.17 or later revisions. The revision info can be found on a small white sticker on the interface and packaging.
2. 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 next page for setting chart).
3. 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 following the procedure outlined on page 3.
4. RSC buttons that are identical to the SWC will mimic the SWC one for one.

Installation Steps

SET RADIO SELECT SWITCH

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. Be sure to connect both Yellow wires (one from vehicle harness and one from RP5 harness) and both Black wires (one from vehicle harness and one from RP5 harness) while making these connections.
3. If the vehicle is equipped with a Premium BOSE system, connect the subwoofer and center channel RCA inputs to the aftermarket radio. If the aftermarket radio to be installed does not have a dedicated center channel or sub output, do not use this cable. To ensure best sound performance, channel summing is not recommended. Use this cable according to the outputs that are available.
4. If the vehicle is equipped with a reverse camera and the aftermarket radio has a reverse camera input, connect the Yellow RCA plug on the Gray connector to the aftermarket radio’s reverse camera input.
5. Plug the CMX chime module in if necessary (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
6. The Mute loop (if not cut) will turn the accessory output off when an OnStar or Bluetooth call is made or received. If the aftermarket radio has a mute input, cut this loop and connect the outer brown wire to the mute input.
7. Connect the SWC wire according to the chart on page 1 (aftermarket radio MUST support a wired remote input).
8. If you wish to reassign functions to the SWC follow the programming instructions in the next section.

Default Steering Wheel Control Programming

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 or utilize short press long press dual command functionality. 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.

Optional Steering Wheel Control Programming

If you wish to re-assign the SWC functions, utilize short press long press dual command functionality or select between Factory function in the chart that your steering wheel does not have, or you do not want to program, press and release the program button function and are ready to proceed to the next one.

SET RADIO SELECT SWITCH .

The Mute button can be set to control the factory OnStar functions or given the ability to control the aftermarket radio. This option can be set using the program button on the side of the interface. The default setting for this button is factory mode which controls the factory OnStar. If this button is set to aftermarket mode, OnStar must be accessed by using the factory controls located on the rearview mirror.

Factory Mode
The SWC Mute button is programmed to control OnStar It cannot be programmed for short press/long press dual command functionality and is blocked from doing so

Aftermarket Mode
OnStar control through the SWC Mute button is disabled. This will free up the Mute button to send mute radio command and another 2nd function.

Use the function chart on the next page as a guide to program the functions in the proper order for your new radio

1. Turn the key to the ignition position.

2. Press and release the programming button on the side of the interface the number of times that corresponds with either
   factory or aftermarket mode. One press will set factory mode, and two presses will set aftermarket mode. The LED will blink each time the button is pressed.

4. To restore the SWC to factory default settings: Simply wait 7 seconds and the LED will blink 3 times indicating the interface has timed out. The default settings are now restored and no further action is required.

5. To program custom SWC assignments: Proceed to step 4

6. At this point you have two options:

7. For short press functionality: Release the button within 1.5 seconds. The LED will turn back on.

8. For long press functionality: Hold the button until the LED starts blinking. Release the button and the LED will go back to solid.

9. If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.

10. 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.

11. 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.

Rear Seat Entertainment (RSE); If equipped

1. Vehicles equipped with an overhead screen only: In this application the GMRVD2 must be used in order to feed A/V into the factory screen from an aftermarket head unit (head unit must support A/V out). With the GMRVD2, A/V will be passed from the aftermarket head unit to the rear screen, and audio can be heard through the headphones. The GMRVD2 will also pass the Auxiliary inputs on the rear of the center console to the aftermarket head unit.
2. Vehicles equipped with an overhead screen AND headrest monitors: In this application the headrest monitors will function independently from the overhead monitor. Neither video or audio can be passed to or from the headrest monitors. The overhead monitor will function exactly as described in #1.
