iDatalink working with GM

iDatalink's HRN-RR-GM3 interface harness allows you to connect an iDatalink-ready car stereo in select 2014-up GM-made vehicles,

working in conjunction with iDatalink's Maestro 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.


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.
