Abstract
A video mirror system for a vehicle includes an interior rearview mirror assembly and a video display screen disposed in a mirror housing and behind a transflective mirror reflector of a transflective reflective element of the interior rearview mirror assembly. Information displayed by the video display screen is viewable by a driver of the equipped vehicle viewing through the transflective mirror reflector when the video display screen is activated and, when the video display screen is not activated, the presence of the video display screen behind the transflective mirror reflector is substantially not discerned by a driver of the equipped vehicle normally viewing the transflective reflective element when operating the equipped vehicle. A compass sensor may be disposed within the mirror housing and behind the transflective reflective element, and the compass sensor may adjust in tandem with adjustment of a rearward field of view of the transflective reflective element.
