First, download the tool:
"official testing tool of kailide" (testing the physical port and baud rate of DVD navigator) or vehicle-specific GPS port testing tool, "GPS idle port testing tool" and "GPS hardware system testing tool".
Second, prepare a TF card.
4G cards can only hold one map; 8G card, which may hold two maps; 16G card, which may hold four maps; 32G card can hold multiple maps, or four maps, plus music, video, etc.
Third, copy all the above three softwares to the new TF card root directory.
Go to Navigator Settings-"Navigation Path Settings", point and start. EXE file, you can measure:
Physical port and baud rate of navigator; Idle port number of navigator;
Hardware system of navigator, such as operating system type, CPU type and frequency, memory, screen resolution, etc. ?
Fourth, according to the situation of the local system, choose to download the map suitable for your machine. "GPS House" and "I love GPS" forums have many cracked map software to download.
5. Decompress the downloaded map compressed package, and then copy its file package to the root directory of TF card.
6. In the main interface of the navigator, in the Navigation Path (or the address of the navigation file), navigate to. Exe application, and then press the "GPS" button on the navigator to start the map.
The vehicle navigation system is the vehicle GPS navigation system. Its built-in GPS antenna will receive the data information transmitted by at least three of the 24 GPS satellites around the earth, and combine it with the electronic map stored in the vehicle navigator to match the position coordinates determined by the GPS satellite signals, so as to determine the accurate position of the vehicle in the electronic map, which is the usual positioning function. On the basis of positioning, you can provide the best driving route, the road ahead and the nearest gas station, restaurant, hotel and other information through the multi-function display.
How to choose car navigation?
Car navigation can be roughly divided into three categories: external navigation, additional navigation and original navigation. What are the advantages and disadvantages of these three kinds of navigation?
External navigation, easy to understand, is a small navigation machine bought from a digital store, fixed in the car, and can be used when plugged in. The price is generally around 200- 1000 RMB. Its advantages are low price and flexible placement, but its disadvantages are large floor space, exposed wire harness and simple function.
Adding navigation, as the name implies, is to modify the purchased vehicle and add car navigation, which is usually embedded in the central control of the vehicle and looks like a car navigator assembled in the factory. Although it looks beautiful, it is usually only matched with the original car. It needs a set of molds that match the original car, and also needs to match the can protocol, and then consider other things such as functions and systems, which means that its background is more noble than external navigation. Depending on the model, the market price is around 2000- 10000 RMB.
What is can protocol? What specifications of accessories, data access methods, data transmission methods, communication methods, error detection methods, electrical signal specifications, etc. are required for navigation production, and there are rules to follow. To understand this, you need to understand the can protocol, which is completely confidential by most automobile manufacturers, so navigation manufacturers need to obtain this protocol from other channels, and the cost is undoubtedly not low.
The advantage of this navigation is that it is beautiful and integrated with the original car. The disadvantage is that the technical level of matching and installation is high, which may also have a certain impact on the wiring harness and installation of the original car.
Finally, focus on the original factory navigation, which is directly produced by the car factory and assembled by the whole car. It can also be understood as the display screen of the driving computer. It is indeed a part of the car, and it is the best in response speed, function and matching degree with the original car, but it is not necessarily the most practical, because some imported models will not only be used for navigation for China consumers, so it may not be more practical than other navigation.
The original navigation cost is undoubtedly the highest for three reasons:
First, the research and development cost is high, and any part of the automobile will affect the quality of the whole vehicle. Therefore, to add navigation to a certain model, we must first verify the feasibility, what impact it has on the car, wiring harness layout, component protection, durability, temperature and humidity adaptability, vibration fatigue, NVH performance and many other verification items. After verification, it is necessary to find a component supplier for development, and various tests are needed in the process. Marx's point of view explains that it takes more socially necessary labor time for the OEM to produce a car with the original car navigation. So it is more expensive! It is so capricious.
There is another important point. For OEMs, the first consideration of everything used in cars is never the user experience, but the reliability and safety. OEM doesn't want customers to experience products with their own lives, so please understand that the user experience is not good. Some people are not used to it. So mobile navigation can be used as a supplement, but pay attention to the temperature limit.
Secondly, the production cost is high, because the assembly process of vehicles with navigation is more complicated and takes longer. It is necessary to add a set of working procedures separately in the assembly workshop, and put in corresponding tools, personnel and working hours.
Third, there are some hidden costs, such as free maps used by customers, but map manufacturers have to charge, and there are many other patented technologies, all of which are charged. After-sales service is also a cost, so a car navigation means that hundreds to thousands of people will work for it from research and development, procurement, production and after-sales.
So car navigation is so expensive, what are its irreplaceable features? Excellent matching, beautiful appearance, high-quality standards, perfect matching and integration with car functions, radios, Bluetooth phones and other functions.
What kind of navigation to choose, different people have different opinions, and it is reasonable that enough is enough, so there is no need to be too entangled in the principle of choosing applications.
