Escalade head unit change question

[scizzle 0]

I have an 04 escalade and am wondering if I get a new Deck from say pioneer a dvd player double din style, can I still have my steering wheel controls? There is a lot more than just audio on my steering wheel pertaining to oil readings and gas readings and mileage and all kinds of stuff. Does anyone know what is all controlled by the current head unit and what can be lost from changing it out?
