I've mounted mine between my rear-view mirror and my headliner. It has an unobstructed view out the front and back of the car, and sits JUST below the tint line of the windsheild, so laser detection isn't interfered with. Also not easily seen from outside the car. Hardwire it into the power in your overhead console for your moonroof, and theres no power cords. Golden.
So far, works like a champ! Pics on my website.
