Axxess has engineered a data interface that combines all of the features of the patented ASWC-1 with additional patent-pending features into one robust solution for new radio installations. When replacing a radio, the AXTC-1 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.
