What does the tracker in the car mean?

The tracker in the car is a positioning device that receives GPS signals from space through the tracker host, analyzes the GPS signals to calculate the earth coordinates, and then reports the location to the monitoring center through wireless networks such as GSM/CDMA. The following is a detailed introduction to GPS trackers: Function: Use GPS satellite positioning terminals to accurately locate, track in real-time, remotely monitor, and prevent theft and hijacking of remote targets (cars). Classification: GPS trackers are divided into two types: strong magnetic non-installation type and wired type. The advantage of wired GPS locators is that they are powered by the car's power supply, enabling 24-hour uninterrupted positioning. The advantage of wireless GPS locators is their good concealment and wide distribution range.

What is the normal mileage for a new car when taking delivery?

Mileage displayed within the range of 0-100 kilometers is considered normal. Under normal circumstances, for domestically produced vehicles, a mileage of generally within 50 kilometers is considered normal, as a car inevitably needs to travel a certain distance from the factory to the 4S dealership. However, for imported vehicles, considering factors such as transportation, port handling, and customs clearance, the mileage generally should not exceed 100 kilometers. There are three key points to note when inspecting a new car: 1. Check the paintwork: The uniformity and smoothness of the seams are the focus of inspection. It is best to compare with two vehicles of the same model. The gaps between the doors, bumpers, and engine hood should be consistent. If the gaps are too large or the width differs from other vehicles, careful consideration is needed; 2. Check the tires: The tires of a new car should have no damage on the sidewalls, and the front tire sidewalls and tread should show no puncture marks. It is ideal if the tread hairs are intact on both front and rear tires, at least the rear tire hairs should be visible. If tread hair marks are missing on both front and rear tires but the odometer shows only a few kilometers, this is abnormal; 3. Check the nameplate: Each vehicle's nameplate corresponds to the unique engine number and chassis number. Verify these numbers with the certificate of conformity to ensure the codes match. Also, check the manufacturing date on the nameplate; the time between delivery and manufacturing should not exceed three months.

Where is the ETC device installed?

The ETC is generally installed in the upper middle part of the front windshield for most vehicles, while for large vehicles like trucks and buses, it is installed in the lower middle part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with pre-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide their valid ID card and the original and photocopy of the vehicle registration certificate. If the application is made by a non-owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. For company vehicles, the required documents are: An introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle registration certificate; The vehicle that needs to have ETC installed. Here are some precautions for installing ETC: Do not obstruct the view, it's best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which can reduce the driver's field of vision. If this is not considered during ETC installation, it can increase the driver's blind spot. Installing it on the right side behind the rearview mirror can avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the blackened areas on the windshield and do not install it where the solar panel can be easily blocked. Do not remove it casually once installed: The button in the middle of the adhesive is an anti-removal lever, connected to a switch underneath. After the electronic tag is installed, the windshield will press the anti-removal lever in. If it is removed casually, the lever will pop out and trigger the switch, locking the electronic tag and making it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device.

What does RST mean on a car?

RST on a car stands for reset, which is the abbreviation of the English word 'reset'. It is usually not a port but just a small hole with a tiny switch inside that can restore the navigation system to factory settings. This means that when the navigation system freezes or the program malfunctions, you can use this button to reset it, and the navigation will function normally again. A common scenario that triggers a reset is when a connection request arrives, but there is no process listening on the destination port. For UDP, when a datagram arrives at a destination port that is not in use, it will generate an ICMP port unreachable message, while TCP uses a reset.
