Here’s how it works

First, you connect the Maestro to your computer using the included USB cable or to your smartphone or other device via Bluetooth, visit, 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 Crutchfield wiring harness or wiring adapter.

Retains steering wheel audio controls

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.

Command center 

The ADS-MRR2 features three programmable outputs which allow you to control relay-driven aftermarket accessories from an iDatalink Serial Port-compatible Kenwood, JVC, Alpine, Sony, or Pioneer in-dash receiver. These outputs can be individually configured to Latch, Toggle, Follow a CAN signal in the car (firmware dependent), or have a custom output configuration, as well as setting Delay On and Delay Off times for each output. You can also assign a steering wheel control button from the vehicle to control one of these outputs. The ADS-MRR2 also features a dedicated port for radar detector integration that allows you to connect to select Escort radar detectors (sold separately). 

Keeping your factory features with an iDatalink-compatible car stereo

If you’re buying a compatible headunit, 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). You’ll also see a list of these features on the way to the Cart with the car stereo you’ve selected.

With 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.

Car stereos that aren’t iDatalink-compatible 

With car stereos that are not iDatalink-compatible, you’ll usually retain your steering wheel controls and the use of your factory amplifier, although retained features vary according to the vehicle. Again, you’ll see a list of features on the way to the Cart.
