I am doing up my 2006 Esclade right now. Love the relocation of the AC controls, and of course that beautiful big OLED. Can you post a little more info on it? Actually considered doing something very similar but stepped away from it because around these here parts it would be too much bait for the bad guys.
So, mine's going to be a lil' more subdued, monitor down low where the clock is. I am going to do mod the roof console and probably locate those controls to the center console or glove box. Do you miss the storage space much?
BTW, where did you put the traction control switch and is the NAV unit still hooked up?
Again, nice pro job, best of luck with it!
