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.
