Auto-dimming mirror questions

Hello,


I just replaced my '01 Stratus with an '05. The '01 had an
auto-dimming rear-view mirror that dimmed whenever it was dark outside.
This was nice. The new one however has a different mirror (either a
Gentex or a Gentex-clone, as it doesn't say Gentex on it anywhere but
looks 95% like their 50-GENK60 mirror) that doesn't seem to dim unless
it's dark outside *and* it detects headlights coming from behind. I
guess this sounds good in theory but 1) it takes a few seconds to react
(too long) to headlights, 2) the headlights have to hit at the right
angle, and 3) it only detects headlights that are within ~15 car
lengths of me.


I'm not at all an electronics guy... But this thing has a sensor on the
front and one on the back, and they appear to be in an "AND"
configuration. Does anyone know of a way to rig this thing so that it
dims when its dark outside (i.e., when there's low light hitting the
front-facing sensor) regardless of whether or not there's light hitting
rear-facing sensor?


Thanks,
James
