Toyota & Scion 2005-2018 radio harness

The iDatalink HRN-HRR-TO1 is an installation harness that lets you fit an aftermarket stereo in select Toyota and Scion models from 2005 to 2018. It works with Maestro RR or RR2 modules to keep the factory wiring intact and avoid extensive splicing during the upgrade. The package includes the ADS-MRR2 interface module for expanded vehicle compatibility.

Retains steering wheel controls and backup camera

The harness preserves steering wheel audio controls and the factory backup camera with any aftermarket radio. It also maintains the vehicle settings personalisation menu when paired with an iDatalink-ready receiver. Factory amplifier retention is supported, and select iDatalink-ready touchscreens can display performance data and gauges.

Replaces factory radio wiring without cutting

This harness replaces the need to cut or splice the original vehicle loom when installing a new head unit. The jump is worthwhile for owners who want a clean, reversible installation that keeps factory features working. It is not for vehicles outside the 2005-2018 Toyota and Scion range or for installations that do not use a Maestro ADS-MRR or ADS-MRR2 module.

Questions about this item

Will the HRN-HRR-TO1 work with my 2018 Toyota factory steering wheel audio controls?

Yes, the harness retains steering wheel audio controls on compatible Toyota and Scion vehicles from 2005 to 2018 when paired with the required Maestro ADS-MRR or ADS-MRR2 module.

How can I confirm the ADS-MRR2 module is functioning after installation?

The module retains the backup camera feed on the new stereo and displays vehicle settings personalization menus on iDatalink-ready receivers, confirming active communication.

Does the box include the Maestro ADS-MRR2 module or must I purchase it separately?

The product title and description list the ADS-MRR2 Interface Module as included, so both the HRN-HRR-TO1 harness and the ADS-MRR2 module are supplied together.
