CRUX Wiring Interface

You'll only be able to retain your steering wheel audio controls with a compatible car stereo made by Alpine, Boss, Blaupunkt, Clarion, Dual, Jensen, JVC, Kenwood, Pioneer, Sony or Soundstream. No other brands are currently compatible. Check the Details tab to see if steering wheel audio controls are retained in your vehicle. Crux's SWRAD-55 interface ensures that you can keep the steering wheel audio controls and the factory amplifier in your Audi when you replace the original radio. Connect this interface to the wires on your new car stereo's wiring harness, and you've covered the power, ground, and factory speaker connections for your new stereo. The SWRAD-55 interface also offers the reverse, illumination, and Vehicle Speed Sensor (V.S.S.) outputs that you'll need if you're installing a navigation receiver. The Crux interface works with either amplified or non-amplified factory systems. See Details for a list of compatible car stereos.
