iDatalink's HRN-RR-HK2 wiring adapter allows you to connect a new iDatalink-compatible car stereo in select 2010-18 Hyundai and Kia vehicles, working in conjunction with iDatalink's Maestro ADS-MRR2 module (sold separately). Once connected, you'll retain the use of your steering wheel audio controls and factory amp in these vehicles.
The package includes connectors that plug in between the Maestro module, your factory 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.
