    wherein said transflective reflective element comprises a main viewing region and a video display viewing region, and wherein said main viewing region is larger than said video display viewing region and encompasses a substantial portion of said mirror reflector of said reflective element;

    a video display for displaying video images, wherein said displayed video images are viewable through said transflective mirror reflector at said video display viewing region of said reflective element;

    an information input display comprising a display representative of a plurality of individual alphanumeric input characters, wherein said plurality of individual alphanumeric input characters of said information input display is backlit by a backlighting device;

    wherein said information input display is disposed behind said reflective element and viewable through said transflective mirror reflector at said main viewing region when said information input display is backlit by said backlighting device, and wherein said information input display is substantially not viewable or discernible to a person viewing said mirror assembly when said mirror assembly is normally mounted in a vehicle and when said information input display is not backlit by said backlighting device;

    wherein said information input display is disposed at said main viewing region of said reflective element so as to provide an information input display that is larger than said video display; and
