Use GPS (Global Positioning System) and electronic map for car navigation. It can tell the driver the shortest or fastest route to the destination conveniently and accurately, and it is a good helper for the driver.
Advantages of car navigation:
1, with large screen and good maneuverability.
The car navigation interface is good and the screen is large. Support three-dimensional map display, and many softwares have real-life maps. Big screen, very cool. Fixed in the car center console, with Bluetooth, driving record, tire pressure monitoring and other functions, and the screen is generally more than 7.0 inches, which can be multi-touched.
2, no flow, ignore the signal
It can receive the data information transmitted by at least three of the 24 GPS satellites over the earth, so as to determine the position of the car, and then the host computer processes it to calculate the best path, so that the navigation is accurate without GPRS or wifi.
3, don't worry about battery life
It is fixed on the center console of the car and directly supplies power to the car. Unless the car runs out of gas, there is no problem of electricity and no electricity.
Vehicle navigation can be classified according to the following aspects:
1, DVD navigation for special vehicles: one for each machine (most of them need to remove the original car CD).
2. Universal type: various models can be retrofitted with frame.
3. Splitter: special navigation subdivision products for special vehicles, without disassembling the original car CD and other parts, upgrade DVD navigation products.
Car navigation background:
Since the advent of highways, there have been maps to guide people. However, as a guide for people, maps often become a source of tension between people. Because the printed map often can't keep up with the changes of the street, it is difficult to identify, which will lead the driver to blame the people in the car next to him for not reading the map and not providing accurate instructions.
Therefore, a satellite navigation system that can accurately and timely navigate and locate cars by using satellite signals at high altitude has become priceless.
