Professional CAN-BUS steering wheel control interface engineered to maintain factory controls with standard audio systems when upgrading to aftermarket headunits
The AERPRO SWMZ4C delivers seamless integration performance through precision-engineered steering wheel control interface designed specifically for Mazda vehicles with standard (non-Bose) audio systems. This professional interface allows complete aftermarket headunit upgrades while maintaining full use of factory steering wheel controls, providing CAN-BUS compatibility with vehicle-specific plug connection that requires no cutting of factory wiring harness, ensuring clean installation that preserves original vehicle integrity while adding modern headunit functionality.
Which Mazda models is this steering wheel control interface compatible with?
This interface is designed for various Mazda models equipped with standard (non-Bose) audio systems. Steering wheel control interfaces vary between models, so use the Aerpro Vehicle Selector to confirm the correct part for your specific Mazda model and year.
Will this interface work with any aftermarket headunit?
The aftermarket headunit must be SWC (Steering Wheel Control) compatible to work with this interface. While the interface retains steering wheel control functionality, the specific functions may vary from OEM operations depending on the aftermarket headunit's capabilities.
Does installation require cutting factory wires?
No wire cutting is required. The interface features a vehicle-specific plug that connects directly into existing wiring harness, preserving factory integrity and making installation clean and reversible.
Is this compatible with Bose amplified audio systems?
No, this interface is specifically designed for Mazda vehicles with standard (non-Bose) audio systems. For Mazda vehicles with Bose amplified systems, use the SWMZ7C interface instead.
What additional outputs does this interface provide?
The interface provides multiple vehicle integration outputs including reverse trigger (purple/white), park brake (green), speed pulse (pink), illumination (orange), and amp remote (blue), enabling full integration with compatible aftermarket headunits.
Can I customize the steering wheel button functions?
Yes, custom button remapping is available using a USB-C cable (sold separately). This allows customization of button functions to match specific aftermarket headunit capabilities and personal preferences.
Professional CAN-BUS Integration System – Connect the SWMZ4C interface between your Mazda's factory wiring and the aftermarket headunit using the vehicle-specific plug. The CAN-BUS technology communicates with your Mazda's standard audio system network to retain steering wheel controls. Multiple output wires provide additional vehicle integration capabilities for comprehensive aftermarket headunit functionality.
