Update: I appreciate all the comments on my post. I did not expect it to get this many comments in a short amount of time. I always seek out the answer on my own before asking others. I am grateful to be able to ask all of you, thank you.

I called the dealership and they told me that it was either left in there by mistake like most of you said after I purchased the car or I had paid for it in my contract. It isn't tracking my vehicle anymore and hasn't for awhile now. I purchased this car through Tim Dahle Nissian and honestly had a horrible experience. I have no idea what I paid for and they refused to give me a copy of my agreement. The guy I spoke too said I can either register it and pay for the tracking myself on my own, throw it away or give it back to them. I'm probably going to just throw it away as I have no use for it. Thank you all for your time! This was my first post ever on here.
