The Total Control Series combines all of the features of the patented AXSWC steering wheel control interface with additional patent-pending data interface features into one robust and convenient solution. When replacing a radio, this interface utilizes patented Auto-Detect technology(1) that automatically detects the vehicle type, radio connection and preset controls, while allowing the ability to dual assign steering wheel controls. It provides NAV outputs, accessory power and a 12-volt illumination output, in addition to retaining R.A.P., balance and fade.
