Idatalink Maestro HRN-RR-GM2 Plug and Play T-Harness for Select GM2 Vehicles (ADS-MRR or ADS-MRR2 module also required)
iDatalink Maestro HRN-RR-GM2 Interface Harness
Connect a new car stereo and retain steering wheel controls, OnStar, factory amp, and warning chimes in select 2010-up GM-made vehicles (ADS-MRR or ADS-MRR2 module also required)
Keep your GM factory features.
iDatalink's HRN-RR-GM2 wiring adapter allows you to connect a new car stereo in select 2010-up 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, USB media player, 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.
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.
