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 uConnect, Satellite Radio 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, Dodge, Jeep and 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.
