iDatalink HRN-HRR-HK1 Vehicle-specific HarnessConnect a new iDatalink-compatible car stereo and retain steering wheel controls in select 2010-19 Hyundai and Kia vehicles (ADS-MRR or ADS-MRR2 module also required)


iDatalink's HRN-HRR-HK1 wiring adapter allows you to connect a new iDatalink-compatible car stereo in select 2010-19 Hyundai and Kia 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. You'll also retain your secondary vehicle display (if equipped), and the climate status display will appear on the new head unit's screen. The interface also adds vehicle information and gauge displays to your new stereo.

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. This harness features an in-line head-unit connector harness, which will plug into their new "Head-unit direct" harnesses for select radio brands. If you're installing a radio that doesn't work with a "Head-unit direct" harness, you simply cut off the plug and connect the wires to the harness included with your new radio.

Keeping your factory cameras and more

This harness allows you to retain the factory backup camera and 360° camera (if equipped) in your Hyundai or Kia, as long as your receiver has the necessary inputs. If you add an aftermarket front and/or side cameras (sold separately) to your iDatalink-compatible head unit with multiple camera inputs, the vehicle's factory auto camera switching feature is also retained. The harness also supplies the outputs (parking brake, reverse, Vehicle Speed Sense [V.S.S.]) required to install a navigation or video receiver as well as 12V accessory power and illumination outputs.

Note: When installing an aftermarket head unit without an iDatalink-compatible serial port, only the steering wheel controls and factory backup camera are retained.

Installation note: The HRN-HRR-HK1 adapter must be used with the iDatalink Maestro ADS-MRR or ADS-MRR2 module to connect a new car stereo to your Hyundai or Kia vehicle.
