Does anyone know anything about an AirTag being put in a vehicle? How to find out if there is one? Thanks so much

Hi All.

I have a Bluetooth pairing of a device I don’t know and it won’t let me remove it. My ex-husband has put me in a messy divorce and I think he did it to his home TV because it says LG. Also I heard he put a tracker to his work iPhone either to my phone and/or perhaps even in my car. How would I know? I keep researching but know nothing about all this crazy stuff. Plz + TY?

Does anyone know how I can remove the Bluetooth device as well as check if there is an AirTag tracker?
