The CTCH1100 interface allows the replacement of a factory radio in select (2004-2018) Chrysler / Dodge / Jeep vehicles with MSCAN or LSFT-CAN databus radios. Using this interface will retain factory features, such as steering wheel controls (SWC), vehicle entertainment system (VES), and the factory audio 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 CTCH1100 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
