Just a question....The title doesn't do justice, though can you change the gauge unit in your car....as in the unit which has your revs, car temp, speed etc etc??? As I will be chucking a DCCD STI Box in my car and it doesn't have the icons on the unit though the STI unit does...obviously.

Let me know if I am not making sense haha

That picture if refering to what I want
