Sold out

Idatalink,ADS-MRR-2 Advanced Car Radio Replacement Interface

Advanced Radio Replacement Interface, Enabling Bluetooth Programming For Ios & Androids

Maestro RR2 adds built-in Bluetooth. Like the original RR, installers must flash the device, or download software to match

the car model. With the new Bluetooth version, the installer may flash the device wirelessly from a smartphone.

He no longer needs to be tethered to a computer.

Additionally, the new RR2 allows Kenwood radios to act as the readout screen for two ESCORT radar detectors:

the iX Ci custom-installed detector and the portable MAX Ci. Drivers can receive alerts and adjust radar settings through the car radio.

(The original RR works with K40 detectors).

The RR2 has three programmable outputs so it is able to link side cameras into the turn signals of new cars to add blind spot detection.

It can also trigger LED lighting so, a lightbar might be controlled by a steering wheel button.

RR2 has the ability to work with 2018 and newer vehicles with a gateway at the OBD2, including Chrysler, Dodge and Jeep vehicles.

The device is backwards compatible with earlier aftermarket radios that worked with the original RR and it will work with all existing T-harnesses.
