I never leave anything in my X. I have mine in the garage and I still don't leave anything inside. When I get my N6 I'm going to make some type of dummy radio faceplate just to put over the N6 so they won't break into my X.
I live on the SS and around here a certain "Group" of people tend to be around late at night just browsing for stuff to steal. Your lucky that was at UIC and not somewhere else. Don't leave anything inside your car. They will break your window for loose change.
Your better off asking for change in the street, nobody here is going to give you a dime.
