Maestro Universal Radio Replacement (ADS-MRR2)

iDatalink Maestro RR2 Interface Module — Delivered by Trail Grid Pro

Upgrade your vehicle’s audio system without giving up the factory features you rely on. The iDatalink Maestro RR2 Interface Module allows you to install an aftermarket head unit in select late-model vehicles while retaining critical OEM functionality like steering wheel controls, factory amplifiers, and integrated vehicle systems.

Designed as the next evolution of the Maestro platform, the RR2 offers faster setup, expanded control options, and greater flexibility—making it the go-to interface for modern vehicle integrations.

Seamless OEM Integration, Simplified Setup

The Maestro RR2 works in conjunction with a vehicle-specific iDatalink harness (sold separately) to bridge your new stereo with your vehicle’s factory wiring. Setup is quick and intuitive, completed via Bluetooth from your smartphone or through a USB connection to your computer using iDatalink’s web-based configuration tool.

Once flashed with the correct firmware, the module is ready to install—just like a traditional wiring interface, but far more powerful.

Retain Steering Wheel Controls & Factory Features

With the RR2, your factory steering wheel audio controls remain fully functional. Using the iDatalink programming interface, each button can be mapped to your preferred radio functions, including optional “press and hold” secondary commands for added control.

When paired with an iDatalink-compatible head unit, the RR2 unlocks advanced OEM feature retention and display capabilities, which may include:

• Factory Bluetooth systems
• Backup cameras
• Vehicle settings menus
• Factory amplifiers and audio tuning
• Safety chimes and alerts
• Select OEM infotainment systems (SYNC®, Uconnect®, OnStar®, and more)

Available features vary by vehicle and head unit.

Advanced Control & Expansion Capabilities

The Maestro RR2 goes beyond basic integration with three programmable outputs that allow you to control relay-driven aftermarket accessories directly from your head unit or steering wheel controls. Each output can be customized to latch, toggle, follow CAN signals, or operate with timed delays.

A dedicated radar detector port also allows integration with select Escort radar detectors (sold separately), keeping your cabin clean and fully integrated.

Compatible with iDatalink & Non-iDatalink Radios

• With iDatalink-ready radios: Gain the most advanced OEM feature retention, touchscreen vehicle data, and expanded control options.
• With non-iDatalink radios: Steering wheel controls and factory amplifier retention are typically preserved, though available features may vary by vehicle.
