Features

Radio Replacement Interface: The CRUX SWRSU-38B 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, Aux input, & USB port) when replacing a factory installed radio in select Subaru vehicles.

Vehicle Compatibility: The CRUX SWRSU-38B radio replacement interface works with the following 2008-2015 Subaru vehicles.

Make Model Year
Subaru Forester 2009-2015
Impreza WRX/STI (without factory navigation) 2008-2014
Legacy 2010-2014
Outback (without factory subwoofer) 2010-2014
XV Crosstreck 2013-2014
Note: Not all listed vehicle will require the included antenna adapter.

Steering Wheel Controls: The CRUX SWRSU-38B 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-38B 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).

Aux Input: The CRUX SWRSU-38B lets you retain your vehicle's 3.5mm Aux input through the use of your aftermarket head unit's rear Aux input. The SWRSU-38B utilizes stereo male RCA jacks to plug into the rear aux input on the back of your aftermarket stereo. If your receiver has a 3.5mm Aux input, you'll need a female stereo RCA to male stereo minijack adapter cable (sold separately).

USB Port: The CRUX SWRSU-38B also lets you retain your vehicle's factory USB port. This port is handy for connecting your USB devices and keeping your phone charged.

Note: The retained factory USB port will not support Apple CarPlay or Android Auto.
