ADS Maestro iDatalink Steering Wheel Interface - Retain Controls

Our review of the ADS Maestro iDatalink Steering Wheel Interface looks at whether this module delivers on the simple promise: connect a new stereo while keeping the car's built-in controls and audio behavior intact. For owners of select 2004-10 Chrysler-made vehicles who want to replace the head unit without losing steering wheel audio buttons, factory chimes, OnStar or the factory amp, this package provides a focused solution. The single biggest reason to buy is straightforward: it pairs an interface module with a Chrysler-specific harness so the vehicle retains critical factory features after an aftermarket stereo install.

Key Features

• Complete kit: Includes the ADS-MRR interface module and the HRN-RR-CH2 Chrysler harness so installers have the matching components needed for these Chrysler models.
• Retain steering wheel controls: Keeps factory steering wheel audio controls functional so drivers do not lose convenience after swapping the stereo.
• Preserve warning chimes: Maintains the vehicle's factory chimes so safety and reminder sounds remain unchanged.
• OnStar compatibility: Retains factory On Star functionality where applicable so telematics remain available.
• Factory amp integration: Keeps the factory amplifier connected so sound quality and speaker performance are preserved with the new head unit.

Who It's For

This product is aimed at DIY installers and professional car audio technicians working on select 2004-10 Chrysler-made vehicles who need a reliable way to keep factory features when installing an aftermarket radio. It is especially useful for owners who value retaining the original steering wheel controls, chimes and the factory amp for sound quality.

Customers who should look elsewhere include those with non-Chrysler vehicles or models outside the supported years, or buyers seeking a completely plug-and-play swap with zero wiring work; some installers reported installation is not entirely hands-off and may require basic wiring experience.
