There are GPS antennas that land on that DCM and the data from that is forwarded over carplay/android auto. Phones fall back to their onboard GPS but it's a much worse experience than we're accustomed to. If you share the car with someone expect complaints. Pulling the cell antenna(s) is the most elegant solution. People shouldn't be afraid of a little work.
I don't use cell phones but still this'll get me in the dashboard sooner than I had intended (never, before).
Hadn't really thought about the car broadcasting its bluetooth/RF . Is the SiriusXM traceable?
