More details on the Crux SWRSU-38A Wiring Interface
Radio Replacement Interface: The CRUX SWRSU-38A is a radio replacement interface for select Subaru vehicles. It facilitates the integration of an aftermarket radio and enables retention of specific factory features (such as steering wheel controls) when replacing a factory installed radio in select Subaru vehicles.
Vehicle Compatibility: The CRUX SWRSU-38A radio replacement interface works with the following 2007-2009 Subaru vehicles (without automatic climate controls).
Steering Wheel Controls: The CRUX SWRSU-38A also features a steering wheel control output for Alpine, Blaupunkt, Boss, Clarion, Dual, Jensen, JVC, Kenwood, Pioneer, Sony, and Soundstream aftermarket head units. The steering wheel control output consists of a right-angle 3.5mm connector and a light blue/yellow wire (use the connection that your aftermarket head unit is outfitted with). There is also an included SWC adapter which converts the right-angle 3.5mm jack into a 3-wire interface for some aftermarket Boss head units. The SWRSU-38A interface module will work with any of the listed aftermarket head units, by setting its 8 dip-switches (see owner's manual for appropriate setting).
