Product overview

The Stinger HRMA004 connects an aftermarket head unit to the factory wiring of the Mazda 3 BL (2009-2013) via a plug and play ISO harness, without cutting or splicing factory wiring.

User-programmable settings for Bose digital amplified gain, fader, and surround sound are also available for customisation after installation.

The OE LCD display continues to function after installation, retaining clock, MPG, estimated miles to empty, and other vehicle information displays. A/C compressor function and rear seat entertainment are also retained. AUX and USB retention are not included. The kit provides 12V ACC, Illumination, VSS, Parking Brake, and Reverse output signals for the connected aftermarket head unit.
