^^^yea unless you figure out some crazy awesome way to wire them to the aftermarket stereo they are useless. I upgraded my stereo and the controls are just for giggles cause they look so out of place. But if i ever want to go back to stock...they are still there.
And welcome as well! You just made the best decision of your life lol.
you could always buy my 9006 i have for sale!!! lol shameless plug aside there are some aftermarket radios you can get an adapter for that will allow you to use the steering wheel controls with the new radio
Maybe this will help out with your controls , And welcome aboard ... http://www.pie.net/search-by-car.aspx I found 4 different steering wheel controls when I typed your car model in , it depends on what type of aftermarket radio you have for which control you need.
