Some cars have more than one GPS locator, which may be wired and wireless, so the GPS detector bought online may only find one of them. If you can't find it, the location information of the car will be leaked at any time. It is recommended to consult a company specializing in GPS testing first. If you want to buy it, you must be able to detect all the GPS positioning equipment in the car. Before, my friend had a demand for this piece, but later I did it in a company in Beijing, and it seems that all of them have been detected. At least now, I haven't heard what he said is located. I don't know the name of their company, but I have product pictures for your reference.
