The PAC Audio ControlPRO SWI-CP2 retains the built-in steering wheel controls in vehicles when replacing the factory radio with an aftermarket radio. It is compatible with today’s most popular vehicles, even with more complex electronic systems, including CANbus, GMLAN, and Class II systems. The simple-to-use module can be configured in multiple ways, via DIP switches, direct from a USB-connected PC, or a button learning procedure. Wiring and vehicle configuration switch settings are provided through the ControlPRO Web-app and Mobile apps for Android and iOS devices. The SWI-CP2 is designed to minimize installation time much faster than any other products available in the market today.Easy to use and time savingWorks on analog (resistive) and data SWC systemsVehicle Configuration by DIP switch, vehicle lookup, and switch setting provided by ControlPRO Apps (PC, iOS, and Android) and by direct flash from ControlPRO Apps for PC (USB connection required)Button learning modeCustomizable button functionsProvides 2 amp, 12 volt ACC output (databus applications)Does not retain HVAC controls found in some GM vehicles
