ACV Steering wheel control interface

This car radio adapter converts the ex-factory steering wheel remote control signals into a format that can be used by retrofit radios. Thus the steering wheel keys can still be used even after the radio has been replaced. The unit connects to the vehicle's original audio harness using the correct pin assignment and forwards the control cables to an ISO interface for the new car radio. The installation usually includes disconnecting the original plug, plugging the adapter in between the vehicle harness and the retrofit radio, and connecting it to the ISO inputs of the retrofit radio. The component translates the manufacturer-specific signals from different Mazda models to support integration when the original sound system comes from BOSE or the factory radio comes from Panasonic or Sanyo. It is intended for installation in compatible Mazda models of different construction years.
