iDatalink's ADS HRN-RR-GM5+

This iDatalink ADS-HRN-RR-GM5+ harness from iDatalink allows you to connect a new car stereo in select 2006-up GM vehicles, working in conjunction with iDatalink's Maestro ADS-MRR module. Once connected, you'll retain the use of your steering wheel audio controls, your factory amp, and your safety warning chimes, along with OnStar® and factory Bluetooth, if present.

The package includes connectors that plug in between the Maestro module, your GM radio's wiring plugs, and your new car stereo. The harness now includes the option of speaker-level outputs to your amp via included plug-in adapters. 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. The package also includes a plug-in remote speaker which reproduces all factory warning chimes and turn signal clicks.

Installation note: This interface harness must be used with the iDatalink Maestro ADS-MRR module to connect a new car stereo to your GM vehicle.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

Crutchfield Customer Review (What's this?)

Easy to setup and you can program your steering controls for the way you want to.

Pros: Very easy to install. Had to only call idata tech support one time for a question about one wire that had a different color than the radio wire to make sure they hooked together.

Cons: None

A must buy

Written By BrownGuy, Virginia on Thursday, November 06, 2014

Crutchfield Customer Review (What's this?)

This is a must buy with the Maestro module. This saved me a lot of time. You don't have to hunt and look for wires required for e-brake, reverse, and many more just plug the harnesses in and you're done.

Pros: Saves time and prevents headaches

Cons: Can be pricy but Crutchfield sells it for 50% off with head units
