It s still a problem with that navigator. What signal does the car navigation system navigate?

What do you mean by yo, the card is good, whether there are documents in it or not, the navigator can recognize it. You said that you built the file by navigating because you deleted everything on the TF card, and the map was in the TF card, which means that the ** piece was also deleted by you, so it was empty. I don't know what brand of navigator you use, it is recommended that you go to the official website of Zhongheng**Kailide map, Zhongheng official website also has the original file of the map, your navigator needs to restore the original file.

The car navigation system is navigated by satellite signals.

Car navigation system Satellite signal is extremely poor Cause: The internal influence of car film.

Solution: Tolerance.

The best solution is naturally to choose a solar film without wireless signal shielding, in fact, as long as it is not some metal solar film, most of the solar film will not affect the wireless signal. You only need to ask about the product sales before purchasing, and the salesman will naturally know the shielding ability of wireless signals.

If the film has been pasted, see if your car navigation system has an external signal receiver socket. If so, adjust the installation position of the GPS signal receiver to a position that is not affected by the solar film, and the car navigation system can be used normally.

Satellite signal positioning is the same as mobile phone positioning.

Navigator, vehicle-mounted and portable, because the navigator is dedicated to navigation, the main function is navigation, as long as it is original or regular special software, the accuracy can be accurate to tens of meters (but the map needs to be upgraded), the reason why you think the accuracy of the mobile phone, there are two possibilities.

1,The version of the navigator you use is too low,Too few functions,Very original style,Basically and the current high-end mobile phone is almost the same,If even the mobile phone is not as good,It can't be called a navigator,You can upgrade the map,Then adjust the various option settings。

2, pure setting problems, you can try to find the settings of the regular options, which have walking, bus, self-driving, home and other function settings, in the map display settings, map magnification and display mode, prompt mode, etc., as long as the choice is right, the navigator will definitely be more comprehensive than the mobile phone navigation, more convenient.

I have installed a mosaic car navigation device in the outside equipment store, and the portable navigation is exactly the same, but the mosaic is more convenient, directly installed on the center console, portable is similar to the ipad style tablet, some navigation size is relatively small, may be a little larger than the mobile phone is limited, just start to use not accustomed, many functions will not be used, but also feel that there is no mobile phone before, but after using it for a while, I found that it is much easier to use than the mobile phone, and mobile phone navigation, basically all need to go traffic,

The landlord means that the map on the mobile phone is more detailed than the map on the navigator, which is generally true. Because the navigator is specifically designed for driving navigation, the focus is on the road situation. Most of the products of mobile phone navigation are unified with mobile phone maps, not only can include all the geographic information on the navigator, but also can accommodate things that cannot be reflected on the navigator or do not want to reflect, such as country roads, residential areas, etc., which makes the mobile phone navigation (electronic map) often richer and more detailed than the map used by the navigator.

It should be that the version of the navigator is not as new as the version of the mobile phone, or the software used by the two is different!

This generally doesn't, it depends on how to use it.

The built-in navigation function on the phone is like the built-in camera function on the phone, you can play with it, but if you want to get a professional camera function, it is better to have a professional digital camera.

In the same way, a professional car navigation system has at least the following advantages:

1. The screen is large. Now the mainstream is inches, 5 inches, 7 inches are often visible, such a large screen, more suitable for expressing map information, but also more suitable for clearly seeing the ramp information when on the overpass, so as not to go wrong;

2. The running speed is fast. Today's navigators come standard with at least 64M RAM and a 2G SD card. The Roman Avenue Navigator has a standard memory card that uses a 4G Kingston card and is guaranteed for 5 years.

In addition to storing rich map information, it can also be used as a digital library with tens of thousands of books.

3. The ** of professional navigator is not expensive. Now a good mobile phone costs about 1000 yuan, if it is with navigation, it may be 2-3000 yuan, and a professional car navigation system, currently 880 yuan** can be obtained, and even free home delivery express.

Yours is portable, or vehicle***.

Answer: This situation occurs after you click "Factory Reset". Before you click on the navigation to see 5 or 3 maps because we tested the machine before sending it out and set it up for you. After you do a factory reset, there is no navigation path.

Solution: Select: "Settings", go to the settings page, and then turn the page.

After turning the page, you see the words "Navigation Path".

Click on "Navigation Path" to enter.

A rectangle will appear in the middle, and you can click on the white arrow behind the rectangle or navigate the path to enter it.

If it's an electric white arrow, then go straight to the SD card. If it is the word dot navigation path, then sdmmc will appear, and you need to double-click sdmmc to enter the sd card.

Then several files will appear, no matter how many they appear, just double-click on the last file (from left to right).

You'll be taken back to the Navigation Paths page, and the path will appear in the rectangle below.

Click on one of the two charts in the upper right corner of the machine to save it.

Complete the navigation path setup.

At this time, you are back to the main interface, click on GPS navigation, and the normal map display will appear.

Suggestion: Don't press "Factory Reset" lightly.

This kind of problem is very common,The solution is to re**install the package,Clean up the memory,Of course,If you are troublesome,You can also**A Tencent map is also good,I have basically no problem with him,The route is more accurate,I think this is the most practical,The most important thing to drive is the route,Everything else is nothing,And then it is very difficult to take a taxi when you don't drive occasionally,You can also take a taxi with a map,It will be easy to meet daily needs。

Hope to solve your problem and give a kind upgrade that needs yours! Thank you!

Let's share today: How to buy a high-quality GPS navigator?

The navigators available on the market are roughly divided into original car all-in-one navigation, car portable navigation, handheld portable navigation and mobile phone navigation. It may be widely used as the original car all-in-one navigation and on-board portable navigation, mainly because the original car and navigation are integrated, and the driver does not need to consider the problem of charging and disassembly.

1. Look at the reaction time.

Different GPS satellite search speed is different, in the cold start state (no power on search satellite behavior within 48 hours) around the location of the search satellite is usually about 45 seconds, of which 30 seconds is for determining the satellite, and the rest of the time is for calculating the location of navigation. If the search time is greater than 60 seconds, it may indicate that the navigation operation speed is slow or the signal of the built-in GPS module is unstable.

2. Look at the function.

When we buy GPS navigators, the most important thing is its parameters and functions, the parameters mainly include screen separation rate, storage capacity, map type, voice navigation, FM transmission, 3D map and GPS operating system and other parameters, as well as waterproof, shockproof, dustproof performance, high temperature resistance, power consumption and other physical indicators.

3. GPS navigator map.

No matter what kind of navigator it is, all functions are based on the geographic information provided by the navigation map, and the more accurate the information on the map, the clearer the path will be! For example, for entrepreneurs who are in a hurry during the rush hour of commuting, if the route of the car navigation is not accurate, they will miss millions of business in minutes!

Therefore, when purchasing a navigator, you must choose a high-quality navigator, and the real-time traffic conditions are more reasonable and accurate!

4. Quality assurance.

Among domestic manufacturers, the product is seriously homogeneous, the innovation of navigators has stopped, and the product quality and function are similar. In this case, it is often difficult to choose a high-quality car navigation system that suits you. Consumers should not blindly pursue brand and appearance, but should pay more attention to quality assurance!

<> the above is a summary of how to choose a navigator, I hope it will help you.

You can choose the Shenzhou line series, the navigation of the Shenzhou line series will be updated in real time, and the national joint insurance, can be upgraded for free, ** is not expensive.

You should choose a smart navigator, and then you should also choose the Beidou brand, the reputation of this brand is very good, and it is highly recommended.

It is better to buy a portable navigator, because the flexibility is relatively high when it is placed, and it can be put away when not in use.

GPS receiver can be selected. It should also have a very good signal, and there should be a very good satellite positioning time in life.
