Vehicle Compatibility

The iDatalink HRN-HRR-GM2 radio replacement harness fits select General Motors vehicles manufactured from 2010 onwards. It enables the installation of an aftermarket receiver while keeping factory features functional. This harness is intended for owners upgrading the stereo in a compatible GM car or truck.

Maestro Module Requirement

The harness requires a separate Maestro ADS-MRR or ADS-MRR2 module to operate. Without that module the harness cannot communicate with the vehicle data bus. Buyers who already own a different interface module will find this harness incompatible with their setup.

Installation Notes

A universal connector on the radio side allows plug-and-play connection when paired with the correct Maestro adapter. The connector can also be removed for traditional hard-wiring if preferred. Incorrect wiring or omitting the required module typically results in lost steering-wheel controls, chimes or amplifier output.
