2014 Subaru BRZ Install

Great Install on a 2014 BRZ. No changes were required per the instructions sent (4/2025) . Very important to note this since there are several outdated harness instructions running around on YouTube/86 Forums for a Sony Headunit install. Will note the 4-Pin Maestro RR input is not shown on the harness assembly drawing for the 86 platform. Obvious connection, but might save others some time if this is shown as a connection back to the head unit. Prevents the double red flash from the Maestro unit. Thanks!

A necessity with Maestro adapters

Not perfect, but if you are using a Maestro RR adapter this is a necessity.

Time waster

The first one had contact pins pop out and another unresolved issue resulting in the rear speakers and TPMS not working. The second fixed those issues. Lack of troubleshooting info resulted in numerous phone calls to Crutchfield and Automotive Data Solutions, and hours of wasted time diagnosing the problems.

useless

if you have a 2018 subaru, do not buy. this is a ridiculous piece of c#*p. more than half of the included cables aren't used, and the ones that are used don't work...

Unit was hard to get updated because the web app didn't work. Had to use multiple computers. OBD adapter causes my accessport to randomly freeze. Requires usb to be able to update unless you remove the unit.

2016 Subaru Outback 2.5 Limited w/HK, Nav, ES

Works as advertised. Used with iData Maestro RR Interface model on 2016 Subaru Outback 2.5 Limited w/HK, Nav, ES. Host vehicle dependent, but you may need to "splice" one or more wires. For instance, I had to splice a single Subaru StarLink wire. The host wire was a single wire in an 8-pin connector. I cut it at the 8-pin, stripped it and used an in-line wago connector to join the host wire to the wire harness.

2016 Subaru Impreza

This harness is fantastic! Used this to install the iDatalink Maestro RR Interface Module in my 2016 Subaru Impreza. There are so many different wires but this made connecting the Maestro unit a breeze. All of the wire color coding matched current standards were needed, the factory wiring connectors all fit perfectly, the instructions were easy to follow (especially the beautiful wiring diagram broken down into easy to follow steps), and I've never used a wiring harness so well labelled! This made what would have been the most time consuming part of the install one of the easiest steps instead.

Can't review your setup without connection to iDatalink

Set this up in my house, because it was below zero outside. Installed radio, then later found not everything worked as expected. You can't review your setup with out the iDatalink connected. So, you can't after the fact go back and see if you should have programmed it differently.

Great but a bit confusing

Plug in play for the most part summarized my installation...however had to call Crutchfield to clarify connections to get my front speakers working. Gray to Blue connection was not intuitive but understand and Crutchfield was there to help quickly. Otherwise very comprehensive setup. Happy I bought it.

I installed this on the base model 2017 Forester. iDatalink provides access to vehicle information that allows me to enjoy another aspect of the Sony AX6000 head unit.

Subaru Forester

once crutchfield sent me the correct equipment, set up was good but long. lots of little things to do to get it correct. Info on website was wrong about the stock stereo and after a 1 hour convo to the help line, even stumped them with what product works. Had to purchase locally an antenna adapter as they forgot to ship one. Luckily my install partner used to do this as a second job many years ago.

OK.could be better

Works ok.finally. Flashed this thing multiple times and kept getting an error (2 red lights flashing) and the head unit wouldn't boot up. Crutchfield even sent me a new head unit. Finally determined with the help of maestro tech support that if you connect the usb cord to power the factory usb hub, it causes this fault. Had to leave the factory usb ports disconnected which is disappointing, as they sold me on being able to use the factory USB's. Also, be careful downloading the pdf wiring instructions. It will be 600 pages and your vehicle may be on page 250.

I have a 2014 Outback 2.5i Premium, with 6sp Manual Transmission. As expected, the Reverse signal from the maestro unit does not function properly. I had to splice into the Reverse Signal on Pin 2 of the 28-pin input for the original radio. Not sure why this harness does not pick up that pin directly. Everything else works!

Makes Connections Easy

If you bought the maestro unit, this is a must. However, what you don't realize if you try to rush is that you won't need everything in this kit. So pay attention to the online instructions specific to your vehicle before ransacking through the packaging. You might find out you only need half of the cables/harnesses that come with it. Oh, and super important that you follow the wiring diagram to a t. I accidentally connected a set of harnesses that I wasn't supposed to and it resulted in the speakers cutting off whenever the light sensor turned off my auto headlights on my 2015 Subaru Legacy. If this is you, look for a green harness that you may have accidentally connected but weren't supposed to. When in doubt, look at the wiring diagram.

iDatalink HRN-HRR-SU2 Vehicle-specific Harness

The iDatalink bundle is fantastic. I replaced OEM radio with a Sony and the extra parts ordered allowed the steering wheel controls to function. They give you way more connectors than you need for your car. I guess it covers all sorts of different vehicles. After getting tech support on the phone and walking me through it...I was up and running. So great!

iDatalink SU2 Harness

Pretty much required if you want to keep your OEM functions, connect directly to your OEM connections, and use all/most of your OEM wiring. All vehicle specific wiring adapters and connections are included so in most cases there is not too much cutting and/or splicing required (depending on vehicle specific functions and new stereo hardware capabilities). As mentioned by other reviewers though, the wiring diagrams and connections information needs to be updated and additional model information added. Mine was fairly easy to figure out based on my OEM functions and OEM adapter connections. I only had a couple "trial and error" connections to complete to get everything working. One additional pro that came with my model car and choice of head unit upgrade was that this harness allowed me to get additional information and features to my new head unit as well as with my OEM hardware.

Great product to keep factory options when replacing factory unit. everything is there to make the switch. Although the included instructions are questionable, after a little research I was able to make all the right connections
