Scosche GM2000SW-WM1 Factory Stereo Interface

The Scosche GM2000SW-WM1 factory stereo replacement interface allows you to replace your factory OEM stereo in 2000-2013 GM vehicles while retaining all safety and warning chimes. It works with factory-amplified premium sound systems. Not designed for OnStar. The OnStar function will be disabled. This interface will maintain the data-controlled +12V switched ACC power for after-market stereo installation. The interface sends the proper “radio healthy” messages to the vehicle computer. Utilizes standard wire color codes for easy installation.
