iDatalink MAESTRO ADS-MRR + HRN-RR-SU1 T-Harness for Subaru 2008 to 2015

iDatalink HRN-RR-SU1 + ADS-MRR

Connect an iDatalink-ready receiver and retain steering wheel controls, factory amp and sub, and backup camera in select 2008-2014 Subaru vehicles

iDatalink plus Subaru 

Working in conjunction with the Maestro ADS-MRR or ADS-MRR2 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.

With your iDatalink-ready car stereo, you'll be able to set up gauges on your receiver's screen to monitor engine performance, tire pressure, and other functions. You'll also be able to read and reset the vehicle's Check Engine codes.

Installation note: The HRN-RR-SU1 harness must be used with the iDatalink Maestro ADS-MRR or ADS-MRR2 module to connect a new car stereo to your Subaru vehicle.

iDatalink Maestro RR Interface Module

Connect a new stereo and retain the steering wheel audio controls and factory amps in select 2006-up vehicles

iDatalink's Maestro ADS-MRR module, along with the correct interface harness for your vehicle, allows you to install a new car stereo in select 2006-up Ford/Lincoln/Mercury, GM, Chrysler/Dodge/Jeep/RAM, Toyota/Scion, Honda/Acura, Fiat, Subaru, Volkswagen/Audi, and other vehicles while retaining your factory steering wheel audio controls and the use of your factory amplifier, if present.

Here's how it works

First, you connect the Maestro to your computer using the included USB cable, visit www.idatalink.com/maestro, and follow the instructions. Once the unit has been "flashed," it's ready to go. Next, you'll either solder or crimp the vehicle-specific Maestro harness (sold separately) to your new receiver's wiring, just like you would with any Crutchfield wiring harness or wiring adapter.

Important Note: You will also need an additional Maestro vehicle-specific wiring harness that connects your new receiver to the ADS-MRR module and your vehicle's wiring. We will automatically add this harness to your Cart at a discounted price when you purchase a new car stereo and this ADS-MRR module.

Retain steering wheel audio controls, too

The ADS-MRR module also allows you to use your factory steering wheel audio controls with your new receiver. Using the intuitive web programming interface, each factory button can be assigned a specific radio function. Better yet, you can also assign a secondary "press and hold" radio function to each factory button, effectively doubling what can be controlled.

Keeping your factory features with an iDatalink-ready car stereo

If you're buying a compatible Kenwood, JVC, Pioneer, Sony, or Alpine receiver, you'll enjoy the outstanding performance of your receiver, plus seamless touchscreen control over most of the factory features in select vehicles.

Chrysler: You'll retain the use of the Uconnect® system (including voice command), along with your steering wheel audio controls and factory amp.

Fiat: You'll retain your vehicle's factory amp, USB port, and backup camera.

Ford: You'll keep your SYNC® system, including the factory Bluetooth, satellite radio (in select vehicles, see Details), steering wheel audio controls, and other great features.

GM: You'll retain the use of OnStar® system, along with your steering wheel audio controls, your factory amp, and safety warning chimes.

Honda: You'll retain your vehicle's steering wheel controls, Bluetooth, aux input, and factory amplifier.
