Working in conjunction with the Maestro ADS-MRR module, iDatalink’s HRN-RR-SU1 interface harness allows you to connect a new iDatalink-ready car stereo in select 2008-14 Subaru vehicles. Once connected, you’ll retain the use of your steering wheel audio controls, your Subaru’s amplifier and subwoofer (including the fader), and the factory back-up camera in these vehicles. This installation harness will not work with car stereos that do not feature an iDatalink serial port.
The package includes connectors that plug in between the Maestro module and your Subaru radio’s wiring plugs. 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.The HRN-RR-SU1 harness must be used with the iDatalink Maestro ADS-MRR module to connect a new car stereo to your Subaru vehicle.
