Steering wheel button control adapter for Mazda ACV SWC 42XMZ005-0

Preserve the original radio control functions from the steering wheel when replacing the factory radio with an aftermarket unit. Depending on vehicle equipment, available functions and the software of the newly installed radio, some functions may be limited or replaced by others. Compare the displayed wiring connectors with the connectors in your vehicle and ensure they match both technically and visually. Verify whether one of the listed OEM head units was originally installed. Before final installation, verify vehicle functionality, system settings and correct operation of the steering wheel control (SWC).
