iDatalink HRN-HRR-GM3 OnStar, backup cam, and Bluetooth in select 2014-20 GM-made vehicles

Product details

iDatalink's HRN-HRR-GM3 interface harness allows you to connect an iDatalink-ready car stereo in select 2014-20 GM-made vehicles, working in conjunction with iDatalink's Maestro ADS-MRR or ADS-MRR2 module. Once connected, you'll retain the use of your steering wheel audio controls, your OnStar® system with its Bluetooth® capability, your factory backup camera, and your warning chimes. Plus, you'll be able to assign secondary functions to your steering wheel audio controls.

Keep in touch with your truck

You'll be able to set up gauges on your receiver's screen to monitor engine performance, tire pressure, and other functions. In addition, you will retain full access to your factory vehicle customization options on your new radio's screen.

Installation

The package includes connectors that plug in between the Maestro module, your vehicle's radio's wiring plugs, and your new car stereo. You'll have to solder or splice together this harness's power/ground, illumination, speaker, and navigation output wires to the corresponding wires on your aftermarket receiver's wiring harness.

Plug directly into your new stereo

This harness also features an in-line head-unit connector harness, which will plug into their new "Head-unit direct" harnesses for select radio brands, which eliminate the need to splice any wires. If you're installing a radio that doesn't work with a "Head-unit direct" harness, you simply cut off the plug and connect the wires to the harness included with your new radio.
