BlendMount is our patent pending mounting process designed to mount your after-market accesories above your rear view mirror and achieve adjustability with a factory-installed look. This BlendMount Kit includes everything needed for a professional looking installation, including extension cable and inline coupler. BlendMount is compatible with rear view mirrors that have a cylindrical-shaped stem between the mirror and the windshield, or a chili-pepper-shaped stem common in Toyota vehicles. BlendMount is not compatible with rear view mirrors that don't have these stems.
