Keep Your OEM Controls with an Aftermarket Stereo

With the iDatalink Maestro ADS-MRR module you'll be able to install an aftermarket stereo in select vehicles and retain your factory steering wheel controls as well as the use of any vehicle settings originally controlled by the factory radio. Premium features such as SYNC, uConnect, Satellite Radio, Rear Seat Entertainment and Visual Parking Assist are retained in select vehicles. The ADS-MRR, when used with the correct interface harness, will work with select late-model Chrysler, Ford, GM or Volkswagen vehicles.

Your first step will be to connect the ADS-MRR to a Windows based PC via the included USB cable and visit the iDatalink website to flash the module. Once it is ready to be installed, all you need to do is wire it to your stereo like you would any other wiring harness or adapter. The additional interface harness is required to connect your receiver, the ADS-MRR module and your vehicle's wiring together.

General Features:

  • Radio Replacement Interface with Steering wheel Control and Factory Amp Integration
  • Allows for integration of factory steering wheel controls and factory amplifier with an aftermarket stereo
  • Each control can be assigned with a secondary "Press & Hold" function
  • Retains info gauges, satellite radio (if applicable), and Diagnostic Trouble Controls in select vehicles when used with select Kenwood and Alpine navigation receivers
  • Retains OnStar, SYNC and uConnect in select vehicles
  • Before installing you must program the adapter at the iDatalink site to work with your particular vehicle
  • Requires USB connection and Windows based computer
  • USB cable included
  • Authorized Dealer
  • 1-year Manufacturer's Warranty

great product

April 17, 2015

I connected this to a Kenwood DDX1701HD in my 2012 Dodge Ram. I didn't like that I couldn't use my existing Sirius xm antenna with this unit, but that is a Chrysler issue. My gauges show up on my HU along with other vehicle info. Before purchasing this and a HU make sure to see what functions your vehicle and HU will allow the maestro to do.

Can I retain my factory back up camera using this product?
Nick H on Mar 16, 2017
Best Answer: It's actually dependent on your factory setup. If the backup cam went through the factory head unit, then yes. If the backup cam went through the rear view mirror like mine did, then it will not go to your new head unit. I paid my local installer to splice my backup cam wire and run it to my new head unit also, so now it feeds to both spots.

Will this work for installing aftermarket radio to 2004 dodge ram with the factory infinity system?
A shopper on Mar 2, 2015
Best Answer: Hello,

Neither of the two harnesses listed in the description, noted below, list your vehicle. This implies it will Not work for your vehicle, because a harness does not exist to integrate it. You must instead consider a harness by Metra/Axxess , the Axxess CHTO-02.

Will this idataLink Maestro ADS work in my 2003 Monte Carlo SS ?
Randy P on Mar 2, 2015
Best Answer: Hello Randy,

No, because the harness for Chevrolet vehicles , link below, does Not include your vehicle. You will need to consider Metra/Scosche/PAC for your harness needs.

Will this work for 2003 Monte Carlo SS with factory amp and steering wheel control with xm factory radio if I purchase this head unit and the idataLink Maestro ADS-MRR together and would I need anything else for installation? Also this car does not have OnStar.

Best Answer: Hello Randy,

First, the idataLink Maestro ADS-MRR is JUST a module, and - as stated in the description - "Compatible with select 2004 and up vehicles using one of the vehicle specific harness" . Unfortunately, there isn't a compatible harness for your vehicle, so an idataLink product will not work. Instead, we suggest the PAC RadioPro RP4-GM11 . It will retain the OEM Amp, SWC, Data controlled accessory, among other features. However, it will NOT retain the OEM XM Radio. Unfortunately, there isn't a harness that will do so. The best approach here, is to pick up the SiriusXM SXV300v1 kit , and migrate your current account to This tuner.
