iDatalink working with Honda
iDatalink's HRN-HRR-HO2 wiring adapter works in conjunction with their Maestro ADS-MRR or ADS-MRR2 module (required, sold separately), allowing you to connect a new iDatalink-ready car stereo in select Honda vehicles. With your iDatalink-ready car stereo, you'll enjoy the outstanding performance of your receiver, plus seamless touchscreen control over most of the factory features in select Honda vehicles, including the use of your steering wheel audio controls, factory amplifier, Bluetooth®, and backup camera, plus your lane watch camera and secondary vehicle display (if equipped). You'll also appreciate the additional features added by the adapter, including the ability to view performance gauges and other vehicle information on your radio's screen.
Maestro module required
The package includes connectors that plug in between the Maestro module and your factory radio's wiring plugs. You'll have to solder or splice together this harness's power/ground, illumination, speaker, and navigation output wires to the corresponding wires on your aftermarket receiver's wiring harness.
Plug directly into your new stereo
This harness also features an in-line head-unit connector harness, which will plug into their new "Head-unit direct" harnesses for select radio brands, which eliminates the need to splice any wires. If you're installing a radio that doesn't work with a "Head-unit direct" harness, you simply cut off the plug and connect the wires to the harness included with your new radio.
Installation note: The HRN-HRR-HO2 harness must be used with the iDatalink Maestro ADS-MRR or ADS-MRR2 module to connect a new car stereo to your Honda-made vehicle.
