iDatalink meets Mazda

iDatalink's iDatalink HRN-HRR-MA2 installation harness simplifies the installation of the Maestro ADS-MRR or ADS-MRR2 Car Radio Replacement Interface module (sold separately) in select Mazda vehicles when replacing your factory radio.

The package includes a harness that plugs in between the Maestro module, your factory radio's wiring plugs, and the serial port on your new car stereo. This harness features an in-line head-unit connector harness, which will plug into their new "Head-unit direct" harnesses for select radio brands. If you're installing a radio that doesn't work with a "Head-unit direct" harness, simply cut off the plug and connect the wires to the harness included with your new radio.

Retain factory features

The HRN-HRR-MA2 harness and interface module retains your vehicle's steering wheel audio controls, factory amplifier, and backup camera with any aftermarket receiver. The harness also supplies the outputs (parking brake, reverse, and VSS [Vehicle Speed Sense]) necessary for installation of a navigation receiver, plus illumination and accessory power outputs.

Extra features with an iDatalink-ready car stereo

If you're buying a compatible iDatalink-ready car stereo, you'll also be able to display gauges and vehicle info on your receiver's screen, plus read and reset engine codes. You'll also keep your side/front/360° cameras if present.

Installation note: The HRN-HRR-MA2 adapter must be used with the iDatalink Maestro ADS-MRR or ADS-MRR2 module to connect a new car stereo to your vehicle.
