The CTFD1100 interface allows the replacement of a factory radio in select vehicles with MSCAN databus radios. Using this interface will retain factory features such as steering wheel controls (SWC), rear seat entertainment (RSE), rear seat controls (RSC) and the THX or Sony amplifier when the original radio is removed. Use of this interface also allows you to program two radio functions to each SWC button by using short press long press dual command functionality. The CTFD1100 also provides data bus driven outputs such as retained accessory power, vehicle speed, illumination, reverse trigger and parking brake.
