About the iDatalink HRN-HRR-GM2

Bob Bihlmayer

Keep your GM factory features

iDatalink's HRN-HRR-GM2 wiring adapter allows you to connect a new car stereo in select 2010-17 GM 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 in these vehicles, as well as your warning chimes, OnStar, factory amplifier, and park assist feature. If you're installing an iDatalink-ready car stereo, you'll also keep your Bluetooth, backup camera, and the Retained Accessory Power feature (RAP).

Keep your GM factory features

iDatalink's HRN-HRR-GM2 wiring adapter allows you to connect a new car stereo in select 2010-17 GM 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 in these vehicles, as well as your warning chimes, OnStar, factory amplifier, and park assist feature. If you're installing an iDatalink-ready car stereo, you'll also keep your Bluetooth, backup camera, and the Retained Accessory Power feature (RAP).

Works with the Maestro module

The package includes connectors that plug in between the Maestro module, your factory radio's wiring plugs, and the serial port on your new car stereo (if present). You'll have to solder or splice together this harness's power/ground, illumination, and speaker 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.

Installation note: The HRN-RR-GM2 adapter must be used with the iDatalink Maestro ADS-MRR or ADS-MRR2 module to connect a new car stereo to your General Motors vehicle.

Product Research

Features

GM Harness: The iDatalink Maestro HRN-HRR-GM2 installation harness greatly simplifies the installation of the Maestro RR or RR2 Car Radio Replacement Interface module (sold separately) in select GM vehicles when replacing your factory radio with an iDatalink Serial Port compatible head unit from Kenwood, JVC, Alpine, Sony, and Pioneer; or other brand of aftermarket head unit.

  • Vehicle Compatibility: Click here for a list of compatible GM vehicles.
  • Radio Compatibility: Click here for a list of fully compatible aftermarket head units with an iDatalink Serial Port.
Notes: The iDatalink Maestro HRN-HRR-GM2 installation harness requires the purchase of the iDatalink Maestro RR or RR2 (sold separately).

Head Unit Connection: The HRN-HRR-GM2 supports iDatalink's Direct T-Harnesses (sold separately) for direct connection to select iDatalink Serial Port compatible head units (including Kenwood, JVC, Alpine, Sony, and Pioneer radios) - replacing the wiring harness that comes with your aftermarket stereo (some hardwiring may still be required). If connecting to an aftermarket head unit that does not support an iDatalink Direct T-Harness, you'll need to cut off and remove the 20-pin black connector from the HRN-HRR-GM2 harness and splice each wire directly to the aftermarket radio's corresponding wire..

Flashing Module via Weblink Desktop: The iDatalink Maestro RR (ADS-MRR) will need to be loaded with correct firmware before installation. The included USB cable plugs into your computer and allows you to "flash" the Maestro RR with the appropriate firmware to prepare it for installation. Simply download Weblink Desktop (for Windows and Mac) onto your computer to access the appropriate firmware. System requirements include -

  • Windows PC (10/8.1/8/7/Vista/XP/2000) or Mac OS X (Mojave [10.14], HighSierra [10.13], Sierra [10.12], El-Capitan [10.11])
  • Available USB port (version 2.0 or 3.0)
  • 4GB RAM or more
  • 200MB available space on HDD
  • Internet connection

Retained Factory Features: When installing select Kenwood, JVC, Alpine, Sony, & Pioneer in-dash receivers which contain an iDatalink serial port, the HNR-RR-GM2 harness along with the iDatalink Maestro RR or RR2 interface module allows you to retain the following GM factory features (if applicable).

  • OnStar & Bluetooth Hands-Free: The vehicle's factory OnStar emergency services system, along with facotry Bluetooth hands-free can be retained.
  • Factory Amplifier: Retains factory amplifier with turn-on, fader, gain, & DSP control.
  • Steering Wheel Controls: Factory steering wheel controls are retained with two function buttons and expandable radio functions.
  • Backup Camera & Park Assist: Factory backup camera is retained with parking guidelines and park assist chimes (chime speaker included); your aftermarket head unit must have a composite video rearview camera input.
  • Vehicle Settings: You can access and modify vehicle settings through a compatible aftermarket head unit's touchscreen.
  • RAP & Warning Chimes: The vehicle's RAP (Retained Accessory Power) & Warning Chimes (external chime module included) are both retained.
  • RSE (Rear Seat Entertainment): Retains factory rear seat entertainment using the iDatalink AVGM2 harness (sold separately).
Note: When installing an aftermarket head unit without the iDatalink Serial Port, only steering wheel control, OnStar, factory amplifier, warning chimes, park assist are retained.

Extra Features: The following Extra features are added when replacing your aftermarket head unit with a compatible iDatalink Serial Port head unit from Kenwood, JVC, Pioneer, or Alpine using the Maestro RR or RR2 Car Radio Replacement Interface module and HRN-HRR-GM2 installation harness.

  • Vehicle Info: Tire Pressure Display, Battery Voltage Display, Read/Reset Engine Codes, and Door Open Status with Warning.
  • Gauges: Selectable Performance Gauges, "Track Pack" Gauges, and Read/Reset Check Engine Codes.

Outputs: The HRN-HRR-GM2 provides Navigation, Accessory Power, and Illumination Outputs to make installation simpler.

  • Accessory Power Output: 12V/15A Accessory Power Output
