if you don't have the infinty system installing an after market stereo is very simple. just pop off the frame around the stereo (it has the climite controls on it as well) there aren't any screws it just pops out and then there are 4 screws to remove the deck from the frame around it. there is also a very nice blot for grounding if it is needed. however where it used to say the radio information it will now say "E Com" I'm working on how to fix that one still.
