I hate that rear autodim feature. On my 2nd gen. . it had a latching lighted buttton on the bottom of the mirror that you could defeat the thing with... and it would stay off until you pressed in and latched the button. The new one can be defeated, but everytime you cycle the ignition switch, it comes back on. I have a tinted slider, so glare from headlights behind is not a problem. When the dim feature is on, you can't see if it's Five-O on your bumper at night. I drive 20,000mi. a year just to get to work each week and with my hours, I drive most of that in the dark. I'm gonna disconnect the damn connector so I don't have to keep remembering to turn it off each time I get in. and drive.
