A few other reviews seemed to have issues with proper dip switch settings and getting everything to work properly, but I had none of these issues. After following the instructions for soldering the wiring connections provided by Crux and setting the switches as per their recommendations, I installed the new headunit in my car and all my steering wheel controls just worked perfectly. Overall it couldn't be simpler. The one note or piece of advice I have, is that the Crux unit has both and "Illumination" wire and a "Dimmer" wire. The harness for the Pioneer unit I installed (DMH-2660NEX if you're curious) only had a "Dimmer" wire, so I connected those two, which didn't trigger the automatic dimming properly for the headunit when the headlights turned on, so I had to reconnect and resolder the "Illumination" wire from the Crux harness to the "Dimmer" wire on the Pioneer harness. But that's more an issue with Pioneers harness design than the Crux design. I would highly recommend this unit, and will be purchasing another in the near future for a WRX I'm buying. Review: After splicing all the wires of the supplied harness with the harness of the aftermarket radio I realized it wasn’t the correct attachment that CRUX supplied for my 2014 Subaru I currently own like they noted on the compatibility. So I was able to purchase the correct harness and spliced the cables of the CRUX adapter and is still didn’t work. I finally gave up and now can’t return it and am out over $70 with no steering wheel control. ## Features - Item Package Dimension:6.6 cm L X9.1 cm W X20.2 cm H - Item Package Weight:0.14 Kilograms - Product Type:Auto Accessory - Country Of Origin: Germany - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07XZVBYS8 | | Brand Name | Crux | | Connector Type | Rca, Din | | Country Of Origin | Germany | | Customer Reviews | 3.8 3.8 out of 5 stars (96) | | Included Components | Harness, Module, SWC Cable | | Item Dimensions | 22.9 x 6.4 x 2.5 centimeters | | Item Type Name | Radio Replacement Interface with Steering Wheel Control Retention for Select Subaru Vehicles 2009 - 2015 | | Manufacturer | Crux Interfacing | | Material Type | ABS Plastic | | Model | SWRSU-38B | | Part Number | SWRSU-38B | | UPC | 850058234663 | | Unit Count | 1 Count | ## Product Details - **Brand:** Crux - **Connector type:** Rca, Din - **Item dimensions L x W x H:** 22.9 x 6.4 x 2.5 centimeters - **Manufacturer:** Crux Interfacing - **Material:** ABS Plastic ## Images ![CRUX SWRSU-38B Subaru Radio Replacement Interface - Image 1](https://m.media-amazon.com/images/I/71I2lqvPULL.jpg) ![CRUX SWRSU-38B Subaru Radio Replacement Interface - Image 2](https://m.media-amazon.com/images/I/61fgRlavoaL.jpg) ![CRUX SWRSU-38B Subaru Radio Replacement Interface - Image 3](https://m.media-amazon.com/images/I/71736Xdn6rL.jpg) ![CRUX SWRSU-38B Subaru Radio Replacement Interface - Image 4](https://m.media-amazon.com/images/I/71cXr51sw9L.jpg) ![CRUX SWRSU-38B Subaru Radio Replacement Interface - Image 5](https://m.media-amazon.com/images/I/812lnS8se5L.jpg) ## Questions & Answers **Q: Will this fit in a 2012 subaru outback with no problems** A: Yes, it should. But the controls may not be exactly how you want them. E.g. the up and down station may be a search function instead of going through your preset. **Q: will this work with the steering wheel, phone pick and hang up blutooth buttons?** A: My buttons are the simplified version, no phone. But it does work great with volumen, mode, mute, track. I few times it has not work, but it seems that after I turn the car on again, the problem is fixed. Hope it useful info for you. **Q: Will this work on 13 Impreza base model without Nav?** A: I put it in a 2014 outback **Q: Comes with manual and works with steering wheel control I assume?** A: Yes it comes with a manual. I was successful in wiring to my 2013 Subaru Legacy. Steering wheel controls for volume and channel. The manual covers dip switch settings but I had to play with the dip switches a bit to get it all working. All in all I am very happy with this product. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***N on 16 May 2025* I ordered this unit for installing a Pioneer unit in my 2010 Subaru Outback.
