What is this Green Light

[Kazoojb]

Just picked up my new Trailhunter, and I love it so far!
One thing I can't figure out though is a small device near the OBD2 port in the drivers footwell with a green light on it.
There is a button that does not do anything on it as well.

Can anyone shed some light (pun intended) on what this thing is for?

I think that is a GPS tracking device that some dealerships put on their cars for theft. The sales manager director must disclose that if there is one on your car they typically do not tell you.
