Axxess has engineered a new 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.
