Features

Radio Replacement Interface: The CRUX SWRSU-38C is a radio replacement interface for select Subaru vehicles. It facilitates the integration of an aftermarket radio to enable retention of certain factory features such as Starlink when replacing the factory-installed radio and is also pre-programmed for retention of steering wheel controls.

Vehicle Compatibility: The CRUX SWRSU-38C radio replacement interface works with the following 2015-up Subaru vehicles equipped with non-amplified factory audio systems.

Make Model Year
Subaru BRZ 2016-2020
Crosstrek 2016-2017
Forester 2017-2018
Impreza 2015-2016
Outback 2015-2020
WRX 2016-2020
WRX (with Navigation) 2015
XV Crosstrek 2015

Note: The CRUX SWRSU-38C is not compatible in vehicles with factory amplifiers.

StarLink Retention: The CRUX SWRSU-38C retains Subaru's factory installed StarLink safety & security system.

Retained Aux Input: The SWRSU-38C will retain your Subaru vehicle's factory Aux input using your new aftermarket stereo's rear-panel Aux input. The included wiring harness is equipped with a set of male stereo RCA jacks that plug into your aftemarket radio's rear-panel Aux input jacks. If your aftermarket head unit features a 3.5mm Aux input, you'll need a stereo minijack-to-RCA adapter (sold separately).

Backup Camera with Reverse Wire: The SWRSU-38C will retain your Subaru vehicle's factory installed backup camera through the use of your new aftemarket stereo's composite video camera input. The included wiring harness features a male composite video RCA connector that plugs into your aftemarket radio's composite video camera input. You aftermarket radio must be equipped with a composite video camera input and built-in video screen. The included harness also has a reverse wire (purple/white) that connects to the reverse wire of your aftemarket radio's harness for automatic rearview switching when your vehicle is put into reverse gear.

Steering Wheel Controls: The CRUX SWRSU-38C features a steering wheel control output for Alpine, Blaupunkt, Clarion, Dual, Jensen, JVC, Kenwood, Pioneer, Sony 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). The SWRSU-38C 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).
