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. Review: Great tech support - 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 ## 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+) Professional Installation is highly recommended. - 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. - ** Professional Installation is highly recommended. Some vehicles may require extra parts which are sold separately and not included. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #28,286 in Electronics ( See Top 100 in Electronics ) #273 in Car Audio Receivers | | Customer Reviews | 4.4 out of 5 stars 262 Reviews | ## Product Details - **Brand:** Idatalink - **Material:** Polyvinyl Chloride (PVC), Copper - **Item dimensions L x W x H:** 10 x 6 x 3 inches - **Cable Type:** proprietary - **Connector Type:** Proprietary ## Images ![Idatalink Maestro ADS-MRR2 Universal Radio Replacement Interface Module - Retain Steering Wheel Audio Controls & Other Factory Features in Select Vehicles (Vehicle-Specific Acc-HU Harness Required) - Image 1](https://m.media-amazon.com/images/I/61ma5DA3UIL.jpg) ![Idatalink Maestro ADS-MRR2 Universal Radio Replacement Interface Module - Retain Steering Wheel Audio Controls & Other Factory Features in Select Vehicles (Vehicle-Specific Acc-HU Harness Required) - Image 2](https://m.media-amazon.com/images/I/61Fhu667tQL.jpg) ![Idatalink Maestro ADS-MRR2 Universal Radio Replacement Interface Module - Retain Steering Wheel Audio Controls & Other Factory Features in Select Vehicles (Vehicle-Specific Acc-HU Harness Required) - Image 3](https://m.media-amazon.com/images/I/71lSap5obJL.jpg) ![Idatalink Maestro ADS-MRR2 Universal Radio Replacement Interface Module - Retain Steering Wheel Audio Controls & Other Factory Features in Select Vehicles (Vehicle-Specific Acc-HU Harness Required) - Image 4](https://m.media-amazon.com/images/I/71lYI0R8mbL.jpg) ![Idatalink Maestro ADS-MRR2 Universal Radio Replacement Interface Module - Retain Steering Wheel Audio Controls & Other Factory Features in Select Vehicles (Vehicle-Specific Acc-HU Harness Required) - Image 5](https://m.media-amazon.com/images/I/61us+rh1M0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing *by S***Y on October 8, 2025* 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. ### ⭐⭐⭐⭐⭐ Great tech support *by K***K on November 24, 2021* 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.

So overall I am very pleased with the product ### ⭐⭐⭐⭐⭐ wow, this thing works amazing. *by K***N on November 16, 2023* 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. ## Frequently Bought Together - Idatalink Maestro ADS-MRR2 Universal Radio Replacement and Steering Wheel Interface - Retain Factory Features & Display Engine Performance Info on Touchscreen When Installing Maestro-Ready Head Unit - Idatalink Maestro Acc-HU-PIO1 Plug and Play Installation T-Harness for Select Pioneer Car Radios - Idatalink Maestro HRN-HRR-TO1 T-Harness for Select Toyota & Scion Vehicles 2005-19, replace the factory radio while retaining steering wheel controls & use of amp (ADS-MRR or ADS-MRR2 module required) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/225766090-idatalink-maestro-ads-mrr2-universal-radio-replacement-interface-module-retain](https://www.desertcart.vn/products/225766090-idatalink-maestro-ads-mrr2-universal-radio-replacement-interface-module-retain) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-18*
