Axxess ASWC-1 Steering Wheel Control Adapter
Our take on the Axxess ASWC by Crutchfield's Zak Billmeier
Are you looking to install an aftermarket stereo in your car, but want to keep your handy steering wheel audio controls? This ASWC interface from Axxess allows you to connect the steering wheel controls in a wide variety of vehicles to almost any brand of aftermarket stereo, including Alpine, Clarion, JVC, Jensen, Kenwood, Pioneer, Sony, and more. (Note: your new stereo must have a 3.5mm steering wheel control or wired remote control input.)
Installation is straightforward - you usually have to connect a few wires to your factory wiring. In most cases, this interface automatically detects which vehicle it's connected to — if not, you can manually program the interface for your vehicle by following a step-by-step process with LED confirmation. Once connected, the adapter's memory retains its programming even if battery power is interrupted. A USB slot lets you keep the ASWC current as updates become available. Dimensions: 2-3/4"W x 11/16"H x 1-7/8"D. Warranty: 1 year.
Installation Note: This adapter will not retain your vehicle's factory Bluetooth functionality. Please identify your vehicle or call an Advisor at 1-888-955-6000 to see if the ASWC adapter is compatible with your vehicle.
Wiring Advisory: You'll usually have to tap or splice into one to three wires in your vehicle at the radio location to connect this interface. If you're using a Metra Axxess OEM integration adapter to connect your new car stereo to your vehicle, then it most likely will have a prewired connector for this Axxess ASWC adapter. In these cases, no additional wiring in required. Axxess does provide custom wiring instructions for all confirmed compatible vehicles on their website.
Awesome product, could have used a little better instructions but once I figured out the wires it's AWESOME and is simple! A must when installing an aftermarket deck and keeping steering wheel controls

Axxess ASWC Reviews
Average Customer Review(s):
Thanks for submitting your review
Overview: The Axxess Steering Wheel Control Interface (ASWC) lets you retain your vehicle's OEM steering wheel controls when replacing the factory radio with an SWC-compatible aftermarket radio.
Wiring Advisory: You'll usually have to hardwire this adapter into your vehicle's wiring. In most vehicles, the factory radio plug does not have a wire dedicated to the steering wheel audio controls, so splicing & soldering is often required. Metra does provide custom wiring instructions for all confirmed compatible vehicles on their website.
Compatibility: The Axxess Steering Wheel Control Interface is universal and can be used on most any vehicle with factory steering wheel controls. The Axxess ASWC-1 supports the following aftermarket head unit manufactures - Pioneer, Sony, Alpine, Kenwood, Eclipse, JVC, Clarion, Dual, Jensen, Visteon, and Valor. The aftermarket head unit must have a SWC (Steering Wheel Control) 3.5mm input or steering wheel remote control input wire (blue/yellow).
Note: Please consult the Crutchfield Car Selector to see if your vehicle and aftermarket head unit is compatible.
Programming: The ASWC can be programmed in one of two ways. It can be done automatically or manually.
- Auto Detection: The Axxess Steering Wheel Control Interface has the ability to auto-detect certain vehicles and aftermarket radios. It will preset the steering wheel controls to the aftermarket radio automatically, so no programming is required.
- Manual Programming: If your vehicle is not auto-detection compatible, you can still manually program the ASWC to your vehicle's factory steering wheel controls and aftermarket head unit.
Reconfiguring Controls: If desired, the ASWC can be manually programmed so you can make your vehicle's steering wheel controls function the way you want them to; limited only by the functions of the aftermarket radio.
LED Feedback: The steering wheel control interface features an integrated LED to indicate programming status.
Non-Volatile Memory: The Axxess ASWC has a non-volatile memory, which means the steering wheel control interface will remember the programming even if the device is disconnected from your vehicle.
