I have always felt that this car should have come from the factory with steering wheel radio controls. When I found out that they were sold on the L.L. Bean edition and Spec B, I knew I could get them to work with my car. And with the awesome help of many members on this board I have been successful. (special thanks to cschneider, for selling me his wheel and controls after he purchased the L.L. Bean wheel, and to Opie for the part numbers, and to everyone who replied to and contributed to the “steering wheel controls” post: http://legacygt.com/forums/showthread.php?t=1388)
Standard disclaimers apply, I am not responsible if you blow up yourself and your car or short out your expensive radio, or discharge your airbag into your groin…
That said, if you hard wired your radar detector, or hooked up a subwoofer, or did the fog light mod, then you can do this.
I did this on a manual transmission Legacy GT, if you have an automatic, then some stuff, most likely, will be different. I will try to tell you when you might come across something different, hopefully you can post back with your results to make this walkthrough perfect. Also if you have a 2.5i and want to try this I would be happy to help you find out if it is possible (I would be shocked if it is not).

Please PM me and let me know if you notice any spelling errors or errors with my process. Also if you get confused on a step or if you think I did not give enough detail then do a search, there are several posts with, for example, better directions on how to remove the stereo.
I would gladly help if someone wants to come to Toledo, Ohio; I think I could do this in about an hour, it should take a first timer about 2 hours.
