1. Show the track

　　If you go to a strange place and someone takes the way when you go, what should I do when I come back? Don't worry, GPS has a track record function, which can record the route of the user's vehicle through, less than 10 meters, and even the difference between two lanes. When you come back, users can start its return function and let it go home smoothly along the route when you come.

　　2. After the user is marked with two points on the car GPS navigation system, the navigation system will automatically design the Z Jiajia route for the owner according to the current location. In addition, it also has a modification function. If the user accidentally misses the intersection, it does not have the Z Jiajia line recommended by the car GPS navigation system. In the location, design a back route back to the main navigation line, or design a Z Jiajia line from sex to the end.

　　3. Speed measurement

　　Through the GPS reception of satellite signals, the specific speed of driving can be calculated, which is much more accurate than the general mileage.

　　4. Steering voice prompt function

　　As long as the vehicle encounters an intersection or turning in front, the vehicle GPS voice system prompts the user to turn the voice prompts. This can avoid car owners from taking detours. It can provide a full -range voice prompt. Drivers can achieve the entire process of navigation without observing the display interface, making driving more secure and comfortable.

　　5. Positioning

　　By receiving satellite signals, GPS can accurately determine its location, with a position error of less than 10 meters. If you bring a map in the machine, you can mark it with a mark on the corresponding position on the map. At the same time, GPS can also replace traditional compass, display direction, replace traditional altitude meters, and display information such as altitude.

　　6. Increase interest points function

　　Since most cities in my country are in the construction stage, new buildings may emerge anytime, anywhere. As a result, the update of electronic maps has also become a problem that many consumers care about. Therefore, when you encounter some target points on some electronic maps, as long as you are interested or consider it necessary, you can add this point or new route to the map. These new interest points, like any of the original points on the map, can be applied to electronic maps to check.
