iDatalink Maestro HRN-HRR-GM3 Radio Replacement T-Harness with Chime Speaker for Select GM Vehicles

The iDatalink Maestro HRN-HRR-GM3 Radio Replacement T-Harness with Chime Speaker for Select GM Vehicles is designed for select 2014-up GM-platform applications whose factory radio and audio system match the current GM3 coverage record. It is not a standalone interface: exact factory equipment and the rest of the installation system determine fit and retained features.

At a Glance

• Supports amplified and non-amplified applications listed in the guide, but does not retain the supported factory amplifier
• Amplified applications require the factory amplifier to be bypassed as specified by the current application guide
• Factory radio, navigation, amplifier, audio package, screen, camera, trim, and firmware qualifiers must be verified before ordering
• Dash kit, antenna adapter, USB adapter, camera adapter, radio, and other application-specific parts are sold separately unless expressly listed

Vehicle Compatibility

Use the table below to find the row that matches your vehicle and factory equipment. The year, make, and model must match, along with the listed factory radio, screen, amplifier, navigation, or other equipment details. If your vehicle does not match a row exactly, contact MCOR before ordering.

Compatibility & What You Need

Important purchasing requirement: This harness is one component of a complete radio-replacement system. It requires a Maestro ADS-MRR or ADS-MRR2 interface, vehicle-specific Weblink programming, a compatible aftermarket radio, and any application-specific dash, antenna, USB, camera, or head-unit-adapter parts. If the vehicle has a supported Bose or other factory amplifier, plan for amplifier bypass; this harness does not retain that amplifier.
