USER MANUAL RP5-GM61 PAC

Introduction and Features

The RP5-GM61 interface allows the replacement of a factory radio in select General Motors vehicles with 29-bit LAN v2, 20-pin and 16-pin connector radios. Using this interface will retain factory features such as BOSE, OnStar, vehicle settings, steering wheel controls (SWC), front and rear park assist and warning chimes when the original radio is removed. The RP5-GM61 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed (VSS), illumination, reverse trigger and parking brake.

Important Notes

1. Please make your vehicle settings selections before removing the factory radio for optimal installation time. Once the radio has been removed, the vehicle settings which are normally selected through the factory radio can be accessed and changed by downloading and installing the PAC RadioPRO PC Application from http://www.pac-audio.com/firmware.

2. Before removing your factory radio, please review the following settings as these will not be retained once the factory radio is removed:

• Ambient Lighting Control

- Teen Driver Feature

- Valet Mode

- Rear Park Assist Symbols displayed on Reverse Camera Image

1. When you plug in the module for the first time, it must go through an initialization process that takes up to 12 seconds. Make sure you have the vehicle running diring this process.

2. The radio select dip-switchs on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle (see page 2 for setting chart).

3. The Voice button can be set to activate the factory OnStar function by using the RadioPRO PC Application. By default, this button is re-programmed to control the aftermarket radios voice function.

4. For retaining OnStar, you must add on an additional RPA-SPK Chime speaker if you are using an aftermarket amplifier on Mids & Highs that can be purchased separately.

5. 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, utilize the buttons that have no initial programming 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 flash 4 times.

• Chevrolet Malibu will require SWC re-mapping. By default volume up / down and track up / down are reversed.

1. Language: In some vehicles the Lauguage setting is controlled over MOST. Please make sure that you adjust this accordingly before removing the radio as this will not show up in most cases after your install.

2. Please reference the vehicles RPO CODE sticker normally located in the vehicles glove box or the underside of the spare tire cover.

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-GM61's harness according to the wiring connections chart on Page.3.
3. If your aftermarket radio has a mute wire, cut the Brown mute loop in Interface Connector 4. After cutting the loop, you will want to use the side that is next to the orange wire in pin 24. This will be used to wire to the Mute wire on your aftermarket radio if available.
4. Plug Interface Connectors 1 & 2 into the appropriate ports on the RP5-GM61 interface (using the diagram on page 1 or the label on the bottom of the interface).
5. The Interface Connector 3 connection port will be dependent upon whether or not the vehicle has a factory amplified system. Plug this connector into the appropriate port on the RP5-GM61 (using the diagram on page 1 or the label on the bottom of the interface).
6. Remove the factory radio and plug in the RP5-GM61's Vehicle Connector 1, 2, & 3 into the factory vehicle harness. Vehicle Connector 3 might not be present in all vehicles. In vehicles with IOA/IOB use Vehicle Connector 7 to adapt your main harness to your vehicle.
7. Vehicle Connectors 4 & 5 are used when removing the factory CD player in the dash and are mandatory that they are plugged in to keep the MOST loop Intact. Failing to plug these in will result in no sound. Not all connectors may be present.
8. Vehicle Connector 6 (GM5CAM-DIS-HAR) will only be used in vehicle with an IOB Build Code and will be connected to the harness that was plugged in to the factory display in the vehicle once removed. This is used to maintain the camera signal in IOB build code vehicles.

IMPORTANT NOTES REGARDING GREEN / BLACK WIRE CONNECTIONS\*

There is a 60" Pigtail that is used for connecting the SWC input to the GM61 module that has a bullet connector on one end, and a loose wire on the other.

This is designed to plug into the matching bullet connector on the GM6X-HAR; both of which have a matching SWC Input label.

Wiring Connections (Con't)

1. Make all connections as described in the chart above. Be sure to review all connections before plugging the harness into your vehicle.
2. In vehicles with an IO5 / IO6 RPO CODE, to retain the steering wheel control buttons you must hardwire them into the RP5-GM61. The wire you need to connect into can be found by removing the steering wheel shroud located beneath the steering wheel column, and accessing the wire in pin 9 at the Black 10-pin connector located at the base of the clock spring. (Fig. 1).

Once you have located the Green/Black wire in the vehicle you must connect the provided 60" Green/ Black wire from the GM61 module. This is a data signal so to ensure consistent operation, it is highly recommended to solder this wired connection. DO NOT cut this wire in half. In some vehicles it may be necessary to remove the cover around the steering column and tag the wire in pin 9 at the Black 10-pin connector located at the base of the clock spring.

1. Plug the CMX chime module in if needed. It is always necessary unless the vehicle is equipped with the factory BOSE amplifier. Connect the CMX to the 2-pin Pigtail labeled "CMX Module" and install the CMX in a place free of obstructions, where it can be easily heard (usually low in the dash facing downward).
2. Connect the SWC wire or the 3.5mm SWC jack to the aftermarket radio according to the chart above (aftermarket radio MUST support a wired remote input).
3. If you wish to reassign functions to the SWC, then follow the programming instructions on page 5.
4. Connect the Red and White RCAs to the aftermarket radios AUX input to retain the factory 3.5mm AUX input jack.
5. If the vehicle was equipped with the base level radio (IO3) and a factory reverse camera, then connect the Yellow RCA in the harness to the reverse camera input on the back of the radio. If your vehicle is equipped with the IO4, IO5 or IO6 system, follow notes "A & B" below for reverse camera retention. Please reference the vehicles RPO CODE sticker normally located in the vehicles glove box or the underside of the spare tire cover. Please Disreguard the Yellow RCA on the main GM6X-HAR when using the CAM-GM51.

a. Connect the supplied CAM-GM51 Harness (Fig.2). The CAM-GM51 harness connects at the Human Machine Interface Control Module (HMICM), not at the radio. The HMICM is normally found behind the glove box in trucks and SUVs, or high in the passenger side kick panel area in other vehicles. The (HMICM) will have the USB and LVDS cables connected to it. (Pictured Below)

b. The factory reverse camera is powered by the vehicle, not the HMICM. The camera will continue to be powered even when disconnected from the HMICM, so no additional wiring is required to supply the camera with power.
