Vehicle Compatibility

This iDatalink harness and ADS-MRR2 module kit is built for select GM vehicles from 2007 to 2016 and other supported brands from 2006 onward. It targets installers and owners who want an aftermarket radio without losing factory steering wheel controls, OnStar, warning chimes or the original amplifier.

Module Dependency

Full functionality requires a Maestro ADS-MRR or ADS-MRR2 module, which is included in this package. The harness alone cannot retain data features or chimes; the interface module translates vehicle bus signals for the aftermarket head unit. Compatible receivers are limited to Alpine, JVC, Kenwood, Sony and Pioneer models that support the Maestro platform.

Factory Retention Upgrade

This kit replaces a basic ISO harness that would sacrifice steering wheel audio controls, OnStar, warning chimes and factory amplifier output. The jump is worth it when the installer needs real-time engine performance data on the touchscreen and a splice-free, in-line connector for faster, cleaner installation.

  • Compatible with Alpine, JVC, Kenwood, Sony and Pioneer head units
