The SWI-CP5 PAC Steering Wheel Control with Bus Data is a universal analog/CAN bus steering wheel control interface with smartphone/PC app programmability. The SWI-CP5 interface allows the retention of steering wheel controls (SWC) rear seat controls (RSC) and retained accessory power (RAP) whenever replacing a factory radio. 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 with audible feedback for programming confirmation. You can create and save custom vehicle configuration files for later use. The highly visible tricolor LED keeps you informed of modules status. The SWI-CP5 retains memory even if power is lost and is equipped with manual learning function for compatibility with unlisted analog vehicles. The SWI-CP5 works in vehicles with either data or analog SWC. Compatible in vehicles equipped with LAN LIN CAN Class II analog or serial data SWC.
