Remote Control Interfaces

PAC Model #SW1-X - Steering Wheel Radio Control Interface
This universal "learning" remote allows you to retain the use of steering wheel or rear seat radio controls when replacing the factory head unit. It will interface most aftermarket stereos into most vehicles with steering wheel or rear seat audio controls, and works with virtually all aftermarket radios with wireless infrared remote capability using the common 38-40kHz carrier frequency. It also retains the use of heater control buttons on GM vehicles. The SWI-X is so universal that you only need one SKU# to cover over 95% of the vehicles made from 1986 to current. New vehicles coming out every year? No problem! Never be stuck with a vehicle specific type interface.

* Works for all major brand radios, including Alpine, Kenwood, Pioneer, JVC, Sony, Clarion, Blaupunkt, Eclipse, Panasonic, Rockford, Sanyo or just about any other brand out there.
* You can assign the buttons on the steering wheel to any infrared function on the remote, so you are never stuck with specific functions you don't want.
* With select Alpine headunits, the SWI-X can be modified to directly plug into the remote port of the Alpine headunit.
* Covers Ford, GM, Chrysler / Dodge, Acura, Audi, BMW, Buick, Cadillac, Chevrolet, GMC, Honda, Hummer, Infiniti, Jaguar, Land Rover, Lincoln, Mazda, Mercury, Mitsubishi, Nissan, Oldsmobile, Pontiac, Saab, Toyota, Volkswagan, and Harley Davidson motor cycles.
