Not the most unique but fully functional & compatible. I also did this in my previous Subie. I use my GPS quite a bit (pizza delivery) & also charge my iPhone with it.
I wanted a new shift knob. The only appealing one was the STi one, but it had the 6 speed grid on it. So, I got this one & did a little "customizing". Now I won't have to explain to anybody why I don't have a 6-speed.
