Get the kind of mirror that sticks to the windshield like http://www.jcwhitney.com/autoparts/ProductDisplay/s-10101/p-3159/c-10101. Or get one from a junkyard and get the special glue at any auto parts store. You can also get a clip-on automatic dimming mirror like http://www.jcwhitney.com/autoparts/ProductDisplay/s-10101/p-2465/c-10101
