BRAND NEW IDATALINK MAESTRO ADS-MRR RR RADIO REPLACEMENT INTERFACE WITH STEERING WHEEL CONTROLS COMES WITH 3 YEAR WARRANTY NOT RETURNED ~ NOT REFURBISHED ~ BRAND NEW FACTORY SEALED iDatalink's Maestro ADS-MRR module, along with the correct interface harness for your vehicle, allows you to install a new car stereo in select 2003-up Ford/Lincoln/Mercury, GM, Chrysler/Dodge/Jeep/RAM, Toyota/Scion, Honda/Acura, Fiat, Subaru, and Volkswagen/Audi vehicles while retaining your factory steering wheel audio controls and the use of your factory amplifier, if present. Here's how it works First, you connect the Maestro to your computer using the included USB cable, visit their 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, just like you would with any wiring harness or wiring adapter. Important Note: You will also need an additional Maestro vehicle-specific wiring harness that connects your new receiver to the ADS-MRR module and your vehicle's wiring. Retain steering wheel audio controls, too The ADS-MRR 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. Keeping your factory features with an iDatalink-ready car stereo If you're buying a compatible Kenwood, JVC, Pioneer, Sony, Alpine, or other compatible brand receiver, you'll enjoy the outstanding performance of your receiver, plus seamless touchscreen control over most of the factory features in select vehicles.
