Stinger HRMA004 Complete Plug & Play Radio Replacement Kit for Mazda 3
Fit an aftermarket head unit in your Mazda 3 without losing steering wheel controls, Bose audio, A/C function, or any other factory feature.
Product Overview
The Stinger HRMA004 is a vehicle-specific radio replacement kit designed for the Mazda 3 BL series (2009–2013). Powered by PAC Audio RadioPRO4 technology, it arrives pre-loaded with amplifier retention software, steering wheel control mapping, and navigation-based output signals saving significant time and cost during installation.
The kit connects your new aftermarket head unit to factory wiring via a plug-and-play ISO harness with zero cutting or splicing.
