Frequently Asked Questions - SWRSU-38E CRUX
What is the CRUX SWRSU-38E used for?
The CRUX SWRSU-38E is a steering wheel control interface that allows you to retain factory steering wheel functions when installing an aftermarket radio.
Is the SWRSU-38E compatible with my Subaru?
This model is designed for select Subaru models. Please check the included compatibility list or the CRUX website to see if your exact year and trim is supported.
Which aftermarket radios work with this interface?
The module works with most aftermarket head units that have a wired or 3.5mm steering wheel remote input, including brands like Pioneer, Sony, Kenwood, JVC, and Alpine.
How do I install the SWRSU-38E?
Connect the included wiring harness between your car and the radio, then plug the 3.5mm jack into the radio's SWC input. Secure the module with the provided tape and ensure all connections are firm.
Do I need to program the steering wheel buttons after installation?
The SWRSU-38E is usually plug and play. If any button does not respond, use your radio's steering wheel control learning menu to manually assign the functions.
Why are my steering wheel controls not responding?
Check that the ground wire is connected and that the SWC wire is properly attached. Also verify the radio is in steering wheel control mode and that no fuses are blown.
Does this interface support factory amplified audio systems?

The operating voltage is 11 to 16 volts DC, so it is intended for standard 12V vehicle electrical systems. Do not use it on 24V trucks without a converter.
