Perhaps for some car owners, I do nt know how to buy car radar navigation products, but do nt worry, let the experts support us, and talked about the five aspects of purchase points.

electronic dog navigator selection machine

1. Choose the brand ---- quality and after-sales are guaranteed

The various GPSs are full of the GPS market, so that consumers do not know how to choose, especially the appearance of miscellaneous cards and cottage products, and attract consumers with low prices as bait. Friends who can use such products are deeply touched.There is no guarantee in terms of service. Once a problem occurs, it can only be dumb.

Big brands are the most assured choices. From the quality of the product to the brand's service, users can guarantee it. Once there is a problem, it can be solved for you.Although the price is more expensive, the brand has spent a lot of manpower, material, energy, and financial resources in all aspects such as R & D, production, service, and marketing.There are noble truths.

2. Whether to pass the quality inspection of the national authoritative institution

Choosing GPS not only depends on the brand, appearance, and functions, but also pay attention to its hardware quality. The reason why miscellaneous and cottage GPS is cheap is precisely because of the original inferiority, minimizing the cost as much as possible, in LCD screens, GPS chips, motherboards, motherboardsIt is difficult to guarantee the processor and other aspects, and the quality of this machine is evident.

The hardware configuration of the brand GPS is more formal, and it must pass the ISO quality production standards (mainly ISO2000 quality certification, ISO14001 environmental certification) and other certifications.Therefore, the quality of the accessories they use can be guaranteed, which improves the overall quality of the product.

3. Whether to adopt a mature plan

The reason why the miscellaneous cards and cottage GPS are cheap because they have adopted a low price solution. The performance of this solution is unstable and prone to quality problems.Buying products with stable performance can ensure quality. Consumers who buy this product can use it with confidence.

4. Function configuration:

Product functions are one aspects that riders value very much. With the development of GPS, various entertainment functions have been implanted in products, such as digital TV, MP3, MP4, MP5, e -books, games, etc.In terms of practical functions, such as navigation, fixed speed measurement, flow speed measurement, real -time road conditions, Bluetooth, FM launch, reversing vision, stock securities, stock securities, etc. are also very important.Consumers must consider their own needs when buying GPS. Although the miscellaneous cards and cottage GPS can be implanted in these functions, due to the inferiority of hardware and backward solutions, it will greatly affect the function of the function, such as searching for Xingxing, such as XingxingSlow, inaccurate positioning, inaccurate speed measurement, poor TV signals, and so on.

5. After -sales service and map upgrade:

Electronic products will inevitably fail, and after -sales service is very important. Large brands have an excellent after -sales service system. Once a problem occurs, it can be solved for you. There is no after -sales service at all.The riders cannot be resolved at all.Consumers should choose navigation maps with simple operation, convenient use, and complete data when buying GPS.

How to install and use the car GPS positioner

1. Find a thread

Consume whether the required terminal accessories and wiring tools are complete.

There are only 3 lines of the simple GPS positioner that need to be connected, so find out the few lines of the bold font in the car first.

GPS positioner red line car power supply positive pole

GPS positioner black line car power supply negative electrode

GPS positioner white line car ACC/key line (detect the engine switch status, must be connected)

2. Install the SIM card

Many friends do not understand why the GPS positioning system should install a mobile phone card. In fact, the SIM card plays an important role in the GPS positioning system. Simply putThe GSM network transmits positioning data to the specified background in the form of GPRS, and finally forms a positioning monitoring system.

Note: Please make sure that the GPS positioning terminal is inserted into the SIM card without power power, and it is easy to burn card.

After SIM is installed, please turn on the spare power switch (on the side), and confirm that SIM will not loosen.

3. Wiring

After installing the card, go back to the first step.Install the line order of various colors to ensure that the joints are not loose or water.Please use the standard car circuit wiring method to connect the wiring process. Do not perfunctory.Instead of wiring, on the one hand, it is easy to make the GPS locator fail to work, and there is a hidden safety hazard for short -circuit fire.

The wire head should be protected with a thermal Tube to ensure that it is not easy to fall off and not inlet.Then bundle it with a waterproof tape and tied with the original car line.

4. Terminal fixation

The GPS positioner is small and easy to conceal.The common fixed position is to remove the main driving/co -driver front baffle. In its internal space, there are underground seats, trunk and other places.On the one hand, it is ensured that the GPS antenna can receive satellite signals normally, and it can ensure that the vehicle is not easy to enter the water and causes the terminal to burn.

Notice:

(1) The GPS antenna (such as the lower black block) signal is easy to be blocked by mixed soil and metal substances, and plastic, human body, fabric, etc. have no effect.Therefore, when fixed, make sure that there is no metal substance cover above the signal receiving surface to ensure that the receiving surface can be facing the sky upwards.It brings fixed flatness through the magic sticker or plastic tie, so that it will not fall off in long -term use.

(2) When the GPS positioner is fixed, there is no distinction between up and down. The terminal can be fixed and fixed through the magic sticker and tie.There will be abnormal noise.

5. activation

After all the above steps are completed, the vehicle is restored.Then activate the license plate number, terminal ID, SIM card number and other information to the Bo Shi customer service personnel, so you can locate the vehicle and manage the vehicle in the computer, mobile phone, and WeChat.Since then, the installation of the GPS positioner is completed.

navigation interface stops Running Recovery method

When using car navigation, you will encounter some problems more or less, when you encounter What should I do when the car navigation system interface stops Running?How to restore the car navigation system interface?The following is The reasons for stopping the operation and solution of the car navigation system interface, let's take a look together.

1. Excessive program cache: In the mobile phone settings-Application-All-Find a procedure that appears to stop Running-clean up data (most mobile phones can be solved through this method);

2. The mobile phone memory is too low: there are many system Running procedures and insufficient memory.

3. The installation location is wrong: Enter the settings-storage-preferred installation location-determined by the system to change the storage location.The program is not compatible: It is recommended to uninstall and reinstall the program or uninstall some procedures that are not compatible with the system;

4. Procedure itself: There are problems with some programs itself. If there is a problem with the software component in the early stage, the program causes a prompt to stop Running.(This situation can be concluded by comparing multiple different brands of machines);

5. If the above method is still stopped after exclusion, it is recommended to restore the factory settings, or redirect the firmware.

Common faults of car navigation systems

GPS cannot use the vehicle power supply

Under normal circumstances, GPS's battery life is about 1-2 hours, so when long-distance driving, vehicle power is needed.However, some car owners found that the prompts are always not bright whenever they use the vehicle power supply.After the inspection, it was found that the fuse of the original cigarette heater was burned, so the external power supply could not be used.At this time, the owner often believes that the quality of the car power supply of the GPS is too poor, but after multiple replacement, the situation is still.

In fact, the reason for the unable to use the vehicle power supply by GPS is not exactly caused by the quality of the vehicle power supply. Some of the reasons are caused by the design of the cigarette lighter.

Simple judgment and solution:

The owner can first observe which interface of his GPS vehicle power supply belongs to which one shows the following figure. When the A -type plug is plugged out, the fuse will occur, while the B plug will not happen.The owner can replace the vehicle power supply of the B plug.

For car owners who use the car plugs using A interface, if you do not want to change the vehicle power supply, you can insert it after starting the car and before the fire off the fire to prevent instant high -voltage burning.If you think this method is troublesome, you can choose to make a simple transformation of the cigarette lighter in the car.The metal piece above the cigarette jack is flat (red standard), so that the GPS cannot use the vehicle power supply.

GPS cannot search for satellite signals

Satellite signals are the basis for GPS to locate and navigation.If you cannot search for a satellite signal, then GPS cannot perform navigation work, which means that your GPS is just a scrap iron.There are 3 cases that cannot search for satellite signals in general GPS:

1. GPS belongs to the cottage in the cottage, and the "use period" is short.

2. The satellite signal is weak, and you can work normally after adjusting the position.

3. Drives from other electrical appliances in the car, it can be used normally after exclusion.

Simple judgment and solution:

To identify the reason why the satellite signal cannot be searched, you can try to locate on an empty Square.Satellite signals are easier to capture on the empty Square, and electrical interference in the car can be excluded.If in this case, it is still impossible to search for satellite signals, then 99%may be that your GPS belongs to a cottage in a cottage, and you should negotiate with the purchase merchant for replacement or even refund.

If you cannot search for signals in the car, when you are close to the window or even the window, you can get a weak signal. We can judge that it is the second case.The ability of GPS Star Search is closely related to the hardware of GPS. Generally, the navigator has built -in antennas. The built -in antenna is relatively small. The receiving original satellite signals are relatively weak, and they cannot even search satellite signals.Owners can choose to install GPS amplifiers to enhance GPS signals.

When using a variety of electrical appliances, such as driving recorders, GPS cannot be used normally.Well, the reason why the GPS signal cannot be searched is most likely the result of the interference of electronic products.Because the signal frequency band is too close, it leads to mutual interference.The owner can choose to use only one of the electrical appliances, or try to wrap the circuit board with Tin foil to eliminate the interference by itself.

The vulnerable to the GPS bracket response to the screen reaction

The three common problems are that the suction cup of the GPS bracket is easy to loosen, and the back clip is easy to break.In the GPS accessories, the bracket is the most prone to problems, especially the suction cup and the back clip.Many car owners report that the quality of the bracket's suction cup is too poor, completely sticky, and the road conditions have fallen slightly; the back clips are also very easy to break, and it will break.

Simple judgment and solution:

In fact, the phenomenon of loosening the suction cup generally occurs after a period of use. When the circular glue part of the suction cup is entered due to the air, the gap is left out of the vacuum part.fall.Frequent paste and extraction can also reduce the attachment function of the suction cup.The owner can wipe the front windshield and navigation bracket suction cups to reduce the gap left in the vacuum part.If the loose time is too frequent, GPS brackets should be replaced to avoid hidden safety hazards.

The back clip is broken, which is more caused by human factors.The unfairly demolition method of the owner makes the back clip that is not sturdy more easily broken.When removing, pay more attention to the direction of the back clip. Unfortunately, you can really be broken. You can buy universal brackets for replacement.

GPS screen reaction is slow

Touch screen life has become an indispensable part of our lives, and GPS is one of the earliest electronic products to apply touch screen technology.Slow screen response will not only affect the query effect of the handwriting input, but also when you click in the query, there may also be deviations.There are two types of screen reactions in general GPS: there will be two types of slow -screen reactions: there will be two types:

1. The screen is damaged by the sharp object

2. Degrees of screen recognition

Simple judgment and solution:

To identify the reason for the slow response of the screen, you can choose to enter the place name in your search destination.If the words in the handwritten box are always intermittent, it is difficult to be coherent, and even divided into multiple parts.Then the touch screen is likely to be damaged by sharp objects.Generally, this situation will only appear when it is more than half a year, and there is no solution.The key is the usual use and maintenance.When input, choose a handwriting pen with GPS, and try not to use the screen or toothpicks with sharp things for a long time as alternative with your fingertips.

The situation of screen recognition is generally reflected in the scope where the user's clicks cannot be accurately identified.For example, when the owner was selected by the route, the "best route" was clicked, while GPS recognized it into an adjacent "high -speed priority".At this time, you can re -adjust the screen.Generally, the screen adjustment is located under "setting", and the GPS of different brands will be slightly different.After entering the adjustment menu, after appearing a "Ten" calibration symbol appeared on the screen, click on the middle position of the handwriting pen to the intermediate position of the cross according to the prompts.

Summary: When the GPS fails, don't rush to blame the quality of the products sold by merchants.We should start with our own habits to see if we have improper use, which has accelerated GPS aging and damage.For GPS, which does have quality problems, the owner should resolutely safeguard his interests and replace the goods or even refund it.
