    Does anybody know a way to calibrate the sensitivity of the auto-dimming mirror?

    Prius owners like us are likely to go blind. In this world of SUV's, we're all in perfect line-of-site of their headlights. I'd like my mirror to dim when sensing less brightness from headlights. How can I turn up the sensitivity?

    Thanks!

    http://john1701a.com/ has information on that. Basically you put a blue piece of transparent plastic over the sensor in the front of the rear view mirror (makes it think it's darker). Another suggestion is a piece of electricians tape covering about 3/4 of the sensor.

    I covered the entire sensor on the windsheild side of the wirror. It does get really dark once you turn the car on, but I simply turn the mirror off so it goes back to normal. At night I turn the mirror back on.

    It NEVER gets dim enough in my opinion.

    Rather than blue tape I suggest getting some scrap window tint material of various darkenesses from a local installer and taping on or more layers of those over the sensor until you find one that gives the degree of dimming you desire.

    Alternatively, I have a parking tag that's designed to be hung from the rear-view mirror. A happy side effect of using that hanger is that it blocks a large amount of the light to the sensor causing significantly strong dimming than before.

    Also, the mirror can be adjust up and down so try and move the mirror as far up as possible.
