About this product
Upgrading the factory radio in a modern, tech-heavy Subaru shouldn't mean sacrificing your favorite features or hacking into your vehicle's complex electronics. The iDatalink Maestro HRN-HRR-SU3 installation T-harness radically simplifies your sound system upgrade. Working in tandem with a Maestro RR or RR2 Car Radio Replacement Interface module (sold separately), this vehicle-specific harness creates a clean digital bridge between your new receiver and your vehicle's factory network. It cuts down on tedious wire tracking and cutting, keeping your dashboard installation safe, secure, and professional. Don't trade away factory conveniences just to get a modern touchscreen. When paired with a compatible iDatalink-ready multimedia receiver, this advanced T-harness lets you retain your Subaru's original steering wheel audio controls, factory backup camera, auxiliary input, and parking assist systems. If your vehicle features a premium Harman Kardon system, it preserves the factory amplifier alongside essential fader controls. Furthermore, it maintains your Subaru Starlink telematics functionality and safely reads real-time computer diagnostics—allowing your new stereo screen to display custom engine performance gauges, exact tire pressure data, and check engine code diagnostics.
