Upgrade your Toyota’s factory radio the right way with the iDatalink HRN-HRR-TO2 Vehicle-Specific Harness. Designed to work with the iDatalink Maestro ADS-MRR or ADS-MRR2 module (sold separately), this harness allows seamless integration of an aftermarket head unit while retaining critical factory features in select 2012–2019 Toyota vehicles.

Once installed, you’ll keep steering wheel audio controls and factory amplifier functionality, ensuring your new radio feels fully integrated—not like an afterthought.

Seamless OEM Integration

The HRN-HRR-TO2 connects directly between your vehicle’s factory radio plugs and the Maestro module. Power, ground, illumination, speaker, and navigation output wires must be spliced or soldered to your aftermarket head unit harness unless you’re using an iDatalink “Head-Unit Direct” compatible radio.

When paired with an iDatalink-ready head unit, this harness unlocks even more factory integration, including on-screen vehicle settings and real-time vehicle data.

Enhanced Features with iDatalink-Ready Radios

When used with a compatible iDatalink-ready stereo, the HRN-HRR-TO2 allows you to retain and display select factory features directly on your radio’s touchscreen, including:

• Backup camera
• Vehicle settings personalization menu
• Auxiliary input
• Fader control
• Performance gauges and vehicle data (with supported radios)

The built-in head-unit connector works with select “Head-Unit Direct” harnesses to eliminate wire splicing. For non-compatible radios, simply remove the connector and hardwire to your radio’s harness.
