SR-GM14H Stinger HEIGH10® Radio Replacement Kit

Introduction and Features

The SR-GM14H is a complete radio replacement kit for the installation of the Stinger HEIGH10® modular radio in Chevrolet Silverado and GMC Sierra trucks. All modules, cables and adapters are included to retain important features of the factory system, including: OnStar, front and rear park assist, warning chimes, factory reverse camera, steering wheel-mounted radio controls and AM/FM reception. Plug & Play wiring harnesses allow for quick and easy installation without the need to cut or splice any wiring. The display mounting panel allows flush mounting the 10 inch display without modifying/cutting any part of the vehicle's sub-dash.

Important Notes

We recommend reading this manual thoroughly to familiarize yourself with the entire process prior to beginning the installation.

• Does not retain the following factory features: Factory satellite radio, Rear seat entertainment system (RSE), Steering wheel control backlighting, Factory USB Ports.
• Not compatible with vehicles equipped with Bose amplified audio system.
• 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 Vehicle Settings program from http://www.pac-audio.com/firmware.
• The Voice button can be set to activate the factory OnStar function when pressed for longer than 1.5 seconds or given the ability to control the aftermarket radio. This option can be found in the PAC Vehicle Settings program mentioned above in note three. The default setting for this button is to control the factory OnStar. If this button is set to control the aftermarket radio, OnStar can still be accessed by using the mirror controls.

Attach the display to the panel using four M4 x 10 screws from the HEIGH10 hardware pack.

Section Five: Radio Module Preparation

Part One: Radio Module Side Brackets

Step 1

From the HEIGH10 hardware, mark the two metal brackets as shown. Make a 90° bend at the solid line and cut along the dotted line.

Step 2

Save the cut off end pieces; they will be used as spacers. From the HEIGH10 hardware, four M5 x 10 screws will be used to attach the brackets.

Step 3

Align one of the 90° side brackets to the left side as shown. Bracket, then spacer and attach with two M5x10 screws in the locations shown.

Step 4

Align the other 90° bracket to the right side as shown. Bracket, then spacer and attach with two M5x10 screws in the locations shown.

Step 5

From the HEIGH10 box, connect the LVDS (Blue USB) and 10 pin display cables to the Radio Module.

Section 5: Radio Unit Installation

Part One: In-Vehicle Harness and Cabling Connections

Step 1A

For IO3, IO4, IO5, IO6: Connect the Green and Gray vehicle side plugs (1) on the RP5 Main Harness to the matching plugs in the vehicle. For IO4, IO5, IO6: If equipped, connect the Yellow CAM-51 Input RCA to CAMERA RCA (2) and connect the male green/black SWC Input to the female SWC lead (3).

Step 1B

For IOB: Connect the Mustard and Gray vehicle side plugs (1) on the RP5 Main Harness to the matching plugs in the vehicle.

Step 2

After the two vehicle side plugs are connected, push the connectors back into the rear access hole as far as possible to make room for when the radio module is installed.

Step 3

Temporarily place the RP5-GM51 module inside the CD/DVD cavity while making the following connections to the HEIGH10 Radio Module.

Step 4

Plug in the two USB cables (1) and the GPS antenna (2).

Step 5

Plug in the HEIGH10's 16 pin Main Harness (1) and 24 pin A/V Harness (2).

Step 6

Connect the radio side of BAA22 Antenna Adapter (1) to the HEIGH10's AM/FM antenna input. Plug in the 6 pin SWC / EXT IR harness (2).

Step 7

2018-19 IOB Only: Plug the 20 pin harness that was removed from the factory display into the GM5CAM-DIS-HAR.

These are the connections for a typical installation. If adding additional cameras, amplifiers or satellite radio, those connections should be made at this point, before mounting the radio module.

Part Two: Radio Unit Mounting

Step 1

With the Chime Module and both display cables routed over the top, place the RP5 interface on top of the radio module and slide it into CD/DVD cavity as noted in Step 2.

Step 2

The plastic panel in front of the CD/DVD cavity is narrower than the cavity itself and will prevent the side bracket screws from passing. The side bracket screws will need be angled up and over this panel as it is put in place.

Step 3

Once in place, secure the radio assembly with two 7mm screws. Zip tie the Chime Module in a suitable location. Use the supplied two-sided tape to secure the RP5 interface to the top of the radio module.

Step 4

Plug the two display cables into the back of the HEIGH10 display. Re-connect the factory climate control connector to the climate controls.

Step 5

Place the mounting panel in place and temporarily secure it with two 7mm screws.

Before reassembly, it is recommended to power up the radio and check the chime volume* and all other functionality, including: Volume, Balance, Fade, AM/FM Reception, Bluetooth, USB, Apple Carplay, Android Auto, Camera(s).

*The Chime Module has a 4 position volume selector on the side. Setting 1 being the loudest and 4 being the quietest.
