An information display for use in vehicles including a module or housing located behind, and attached to, a support for the interior rearview mirror assembly. The module includes a display which is observable around the profile of the mirror by the vehicle operator or passengers. An upper portion of the display module is attached to the mount used to support the mirror assembly on the vehicle windshield. The upper portion of the module may be detachably coupled to the mount by a snap-on clip, by a threaded fastener secured directly to the mount, or by a resilient S-clip. The information display of this invention lends itself to quickly and inexpensively adding a wide range of information displays such as a compass, trip computer, clock, warning light, temperature readout, or the like, to any vehicle, at a location readily seen by the vehicle operator within the forward field of vision without substantially interfering or impairing the operator's field of vision.
