So I've read that if you don't have the navigation system, you should have a dash top storage bin. I've had my X3 2.5 for less than a week, but I am almost certain I don't have a storage bin on the top, there's a panel, but no way of opening it. Should I have a storage bin, is there a way to open the panel? I would really like a strorage bin... does anyone else have one?
