I've heard that there are more than just external tracking devices, and some GPS navigation will also collect personal data to track you. So how do I avoid this kind of tracking?
Tracking devices can now be easily purchased online, so anyone can install a tracking device in your car. In addition, as you said, GPS navigation and some mobile apps also have tracking features, and your whereabouts are easily known to others.
In response to this, the research institute has developed a device designed specifically for civilian GPS signals. The GPS jammer can block a variety of GPS signals. It can also jam mobile phone signal options. Can ensure that the driver will not distracted while driving.
