Designed for 2016+ Hyundai and Kia

This iDatalink HRN-HRR-HK3 installation harness works exclusively with the Maestro ADS-MRR2 module in select 2016 and newer Hyundai and Kia vehicles. It supports both non-amplified and factory-amplified audio systems when the optional RSPDIF adapter is used. The harness enables an aftermarket receiver while keeping the vehicle's original wiring intact.

Retains steering wheel controls and cameras

Under continuous daily use the harness maintains steering wheel audio controls, hard panel radio buttons and audio or phone data shown in the instrument cluster. Factory backup, front and side cameras stay operational provided the new receiver offers a second camera input. The Rear Seat Entertainment system and climate status display also remain functional.

Provides data outputs without extra modules

The harness supplies parking brake, reverse and Vehicle Speed Sensor outputs directly to the aftermarket radio for navigation features. Engine and vehicle performance data can be shown on the touchscreen through the Maestro RR2 connection. No additional interface boxes are required for these retained functions.

Questions about this item

Does the ADS-MRR2 module generate heat or draw noticeable power during continuous operation?

The ADS-MRR2 module is a low-current data interface that produces no measurable heat and draws negligible power from the vehicle's electrical system during all-day use.

What aftermarket receiver features are required to keep my factory backup camera and front/side cameras with this harness?

The receiver must support a second camera input to retain the factory front and side cameras, while the backup camera works with standard rear-view camera inputs on compatible head units.

Will this harness work with my existing factory amplified audio system in a 2016 Hyundai or Kia?

Yes, it supports amplified systems when the optional RSPDIF adapter is added; without it, the harness retains steering wheel controls, cameras and cluster data but bypasses the factory amplifier.
