I have the Auto-headlights with the electro-dimming rearview mirror. Mine is an 2003 XLT-Premium with only the Cargo Cage as an additional option.
I have the upper an lower consoles, power drivers seat, and step bars
If it gets too dark before your auto-headlights turn on, you can tape a piece of dark window tint over the sensor on the back of the mirror. That worked perfectly for me.
If you use a piece that is too dark or to layers you will notice that your mirror dims during the day?? I think there must be some comparison of the light coming from the front sensor and the light hitting the rear sensor. If the front is too dark it thinks it's night time and the sunlight from the rear makes it think there is a vehicle behind you with bright headlights....Just what it's supposed to do.
