Put it on the dash, centered, above the windshield wiper so it's a strait view ahead, level it front, back and sides if on the window cups? I'm thinking I need a suit tailor to place this plastic toy correctly. Well I'll let you in on a secrete, mount it on the dash in full sunlight, no lidar view to the rear, and right where the thugs love it, and after the heat of the dash, sunlight, while the electronics heat internally, that means you just bought their next radar detector after your unit thermally overloads. So, those companies we trust want you to destroy your expensive investment only to sell you a new one? Well. YES! Don't do as the instructions say on this one, read my previous posts and go from there.
