Features
- iDatalink's Maestro ADS-MRR2 module, along with the correct "HRN-HRR" Series plug & play t-harness interface for your vehicle, allows you to install a new car stereo in select late-model Chrysler, Fiat, Ford, General Motors, Honda/Acura, Subaru, Toyota/Scion, and Volkswagen vehicles while retaining your steering wheel audio controls and other factory conveniences you've grown accustomed to. And setup only takes a few minutes via Bluetooth from your smartphone or other device, a big improvement over previous models. Vehicle (Coverage: 30 Makes - Models: 4582 - Years: 2002+)
- If you're buying a Idatalaink Maestro compatible Alpine, Boss, Kenwood, JVC, Pioneer or S O N Y receiver, you'll enjoy the outstanding performance of your receiver, plus seamless touchscreen control over most of the factory features in select vehicles (see Details for specific functions and installation notes).
- HEADUNIT INSTALLATION NOTE: This ADS-MRR2 module REQUIRES both the vehicle specific iDatalink Maestro "HRN-HRR" Series Plug & Play T-Harness and the corresponding brand specific car stereo head-unit "ACC-HU" series harness. (Alpine ACC-HU-ALP1) , (Pioneer ACC-HU-PIO1), (S0NY ACC-HU-SON1), (KENWO0D/JVC with 22-Pin Connector ACC-HU-KEN1), (KENWO0D/JVC with 16-Pin Connector ACC-HU-KEN2), (KENWO0D/JVC with 22-Pin Connector 2024+ ACC-HU-KEN3), (Boss Radio ACC-HU-BOS1) or the (Jensen ACC-HU-JEN1) Installation T-Harness. Each Sold separately. These adapters allows you to directly connect select car stereos to compatible iDatalink T-harnesses.
- retains factory convenience features (OnStar, SYNC, Uconnect, and more) with select iDatalink-ready receiversWith most iDatalink-compatible car stereos, you'll also be able to add additional features like performance gauges, climate controls, and parking assistance that appear on your new receiver's touchscreen.
- The ADS-MRR2 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. It's simple to update the module's firmware and software via a wireless Bluetooth connection.
- First, you connect the Maestro to your computer using the included USB cable or to your smartphone or other device via Bluetooth, visit idatalink/maestro website, 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.

Amazing. Lots of options. Ability to turn off auto start/stop on 2015 on up F150s but has the potential to do WAY more. Highly involved install and a must if swapping to aftermarket headunit to keep steering controls.

What an amazing product with the most thorough instructions. In my application 2018 Subaru Legacy with the Harmon Kardon stereo with separate amp I had a lot of questions before starting. When you flash the unit it will have an instruction manual specific to your application, it is so thorough you need to put the seral number for the head unit in in order to flash the unit. Incase someone else is in the same boat as I was in you can retain the stock amp but you will only be using one set of preouts and they need to be the front ones( I found this out the hard way as the phone calls and other voices only come across on the front input), in my case I was not able to retain the factory mike but that is minor, there are two units bolted to the stock head unit you will need to retain both modules if you want starlink & eyesight to work. You will need to wire the power and several other wires but the instructions are very clear.

The product and apps supporting seem to be solid and work as expected. The thing that impressed me the most was the tech support. I had a couple of issues with ApplePlay competing with UConnect and decided to give their support a try. Someone who was very knowledgeable answers the phone and was able to quick advise me on correct application. This is important as the product supports so many different variations of head units, cars, and installed features. In spite of the assistance I still has a minor issue with the final result, but about a month later they came out with a firmware update that applied to my vehicle and stereo head unit that corrected the problem. Which tells me they support their product after it ships. So many tech products these days don't do that. So overall I am very pleased with the product

A must have for installing an aftermarket radio. I used it to wire my new Pioneer to my 15 Jeep Wrangler so I keep all my old steering wheel buttons and get vehicle info on the radio. But the best part is the team at Maestro. I wrote on their forums about a firmware idea I had to hook up the dimmer switch so I could drive with the headlights on during the day without the radio dimming. The very next morning they had a custom firmware pushed to my account and it worked perfectly. Between the steering wheel media buttons and that, it was worth the money. As far as this vs the first gen RR, I personally don't need the extra outputs (although I like having the option). I like that it's thinner and that you can flash the firmware via Bluetooth, but Bluetooth flashing is currently in beta and only works if the module is plugged into a wall, not the car, so its usefulness is fairly limited. I imagine that will improve with time. For an extra $20 I'd say the promise of eventually useful bluetooth flashing isn't bad.

Pro: It works as long as you read directions. Cons: Without the install kit from Crutchfield, you will have a hell of a time with splicing and matching wires. The only thing you need to make sure you do correctly is flash the drive with the correct make and model of your vehicle. You can't cheat this thing into giving you more than you actually have from your old double din radio. The install kits from Crutchfield saved me an hour or so of time, because this piece of kit has the worst instructions ever invented. Save yourself hours of work and frustration by buying the install kit for your vehicle. It took a few hours to install as many of the connections that should be labeled just aren't. You are in the dark without the kit- unless your are professional installer. Much luck.

I wanted to like both the RR1 and the RR2, but it let me down in my daughter's Mitsubishi Outlander with the factory Rockford Fosgate amplifier. While it promised to integrate and work with the amplifier and steering wheel controls, it did, but not fully. The audio will cut out randomly for a second many times while driving, sometimes once a minute, and other times a few times. Support was great, and they addressed some incorrect instructions in their documentation, but in the end, they are waiting to get this car so they can address the problem. For now, that doesn't help my daughter, so I ended up removing the factory amplifier, so I don't need this expensive adapter for the steering wheel controls. Their support was great, and this is unique, so I am giving them three stars.

This interface is needed to keep most if not all oem functions of your steering wheel controls and options from the original HU. This model was used on a 2011 Ford Expedition with oem sync and navigation that had a Kenwood 1037s HU installed. There were initial issues with flashing this unit but those were solved by using the maestro WEBSITE using IE with windows10. Using the weblink app proved to be unsuccessful when flashing. The reason for the missing star is I still haven’t gotten the Sync Voice and media Bluetooth to work from the steering wheel controls but it isn’t a deal breaker as I use Apple Car Play and use Siri for voice commands. Wiring is fairly straightforward as it was all plug and play except for the speaker wires and the Sync wire. That has to be hard wired in the center console and there lies my issue. I will update this review when all problems are resolved. I used the RR2 vice the RR in case I want to install a radar detector in the future. This is a must have to install aftermarket HU’s into newer vehicles for a plug and play install. One thing I personally did different form the install instructions was not to cut the rca cable connectors off the maestro wiring harness. I instead installed rca connectors onto the HU wiring harness thus saving the option of installing an aftermarket amp and having the rca connectors available to plug into the Kenwood.
