Just wondering of anyone else has the same problem as me. My rearview mirror dims so slow it is useless. At night I don't even notice it dimming at all. It is working cos if I shine a torch at the sensor at night or just cover the front facing sensor in day time it does dim but it takes about 30 seconds to dim fully. If someone is blinding me I have to move the mirror which sort of defeats the object of having it. Any thoughts welcome.
