A navigational mirror system for a vehicle includes an interior rearview mirror having a reflective element. A display, optionally a video display, is disposed to the rear of the reflective element and emits light when actuated that passes through the reflective element to be visible to a driver of the vehicle viewing a front portion of the reflective mirror element. A user input comprising a destination address is provided from a driver of the vehicle when the vehicle is at an initial geographic location. The display displays driving instructions that provide instructions to the destination address. The driving instructions are viewable by a person viewing the front portion of the reflective element. A particular instruction of the driving instructions is preferably displayed when it is appropriate to display the particular instruction to the driver of the vehicle.
