Unfortunately, this dish has kept only 20 minutes, then it is slid down. He needs just a horizontal and flat surface, then the idea is for this tiptop. Got the Basics ,, dash mount ordered from Amazon ,,, although slightly larger, but keeps better. This lies behind the screen (Mercedes B Class) on and sits therefore super good and can not slip down. That part I can put into the compartment when not in use and you're done. The attachment to the disc is unnecessary.
