If you have physical access to a car and want to phone home, may I recommend leaving a gps tracking device under the floormat.
replyIt works on more brands of cars too than just one gen of honda civics, and probably quicker to install.
Ah but that is expensive and introduces risk of being caught doing clandestine. It is much more convenient to just use the one already installed and accepted.
replyIn fact, put away all this physical access nonsense and just buy it from the data broker.
