HRN-HRR-GM4 iDatalink Maestro Radio Replacement T-Harness with Chime Speaker (GM)

With its built-in chime speaker, the HRN-HRR-GM4 keeps a GM vehicle's alert tones working after the factory radio comes out. It's part of iDatalink's Maestro T-harness range, connecting the new deck through plug-in connections rather than cut wires.

We stock three GM chime harnesses because applications vary by model and year — this is one of them, so confirm yours before checkout. Our Chilliwack installers can verify the fit and do the work in the same visit.
