iDatalink HRN-HRR-GM3 Radio Replacement Harness with ADS-MRR Interface Module

The iDatalink HRN-HRR-GM3 is an installation harness and chime speaker designed for use with Maestro RR or RR2 modules, compatible with select GM vehicles from 2014 and newer. It supports both non-amplified and amplified systems, though it does not retain the factory amplifier, which must be bypassed during installation. For a simplified and cleaner setup, optional head unit adapters are available for most major radio brands, making this harness an ideal solution for upgrading your factory stereo while retaining essential vehicle functions.
