There is a location inside the dash above the heater vents that is localized by a page where the antenna should locate. I got one included inside my owners package when I bought my car. The install kit should have that page if you bought the radio (antenna should also be in that kit). I can look for that page but I have no idea how to get you a copy of the page. It installs way up inside the dash about center of the vehicle. Did you try the service manuals for the location?
