 When you say "engine 0.0," do you mean "Entune 0.0?" If so, I don't think you'll find many (any?) favorable comments around here about that. I tried Entune 0.0 on my 0000 Prime Premium. That was a waste of time! You can already do the windows and air conditioner with your key fob, but it might not be programmed for the windows. This is something the dealer would need to program unless you have Carista, Techstream, or some other tool for programming these features.
