I was just asked this question from a member of the Z Club of Houston...and I don't have a clue.
Can someone help?
Is there a sensitivity adjustment on the auto-dimming rear-view mirror?
Thanks,

There's only a on/off button, you can have it OFF = like a normal rear view mirror or ON, which is "auto-dimming" you can't adjust it, as the name says, it auto senses the dimming according to the darkness or brightness.
