If the car is paid in installments, the car market will choose to install gps positioning in the car to master the running state and trajectory of the car, so as to reduce car theft and non-payment of the balance. If it's full, you can ask if there is no such equipment in it. If you are not at ease, you can check it yourself. Many gps will be disguised as Bluetooth audio or some small devices, and some wireless GPS will be hidden deep and can be installed in the iron compartment of the trunk. I suggest you find some professional gps installers to help you check the demolition. For example, in Jingzhou, we will find Chufeng electronic technology. Because some equipment is connected to the oil circuit, the wrong disassembly will affect the vehicle.
