So I while driving my family's 2002 Avalanche, I looked up and noticed something I've never once noticed before for the entire 3 years we've owned it. I asked my mom and she doesn't remember ever seeing it before either. It doesn't look exactly factory, and seems to be clipped over the dome light/sunglasses holder, and doesn't seem to have any wires running to it. I can't seem to easily get it off without potentially breaking something, but I'm curious as to what it is. My mom and I are the only ones who drive and have access to it, so we're curious if someone has slipped it in for some reason or if we're both just completely oblivious and have never noticed it before today. Sorry for the potentially crappy picture. I couldn't get it to focus for shit.
