I found this black sticker attached (coming off) to the front side of the rear view mirror.
Not sure what it does. My guess is to enhance or block signals.
Type on sticker "ALIEN" 2011

An ID service tag for the dealer?

Yup, dealership rfid tag. Mine didn't / won't get one. (They can tell when I'm late > )

Many other makes have the same design.
