I heard that car GPS signal jammers are devices specifically designed to block satellite signals. Plugged into the cigarette lighter, they automatically emit interference waves, disabling all GPS receivers within a range of dozens of meters. A friend who works in transportation tried one before, only to find his own dashcam malfunctioning as well—without speed alerts, he almost got a ticket. Most of these devices are smuggled in from small overseas workshops and sold online covertly at prices ranging from a few hundred yuan. However, most countries strictly prohibit their use, and getting caught could result in hefty fines or even vehicle confiscation. If you really want to prevent tracking, it's safer to simply remove the SIM card from the car's infotainment system—this way, you won't affect innocent passersby either.
