Frequently faults of GPS navigation instruments and 10 common problems solving car navigation equipment for car navigation equipment

Common faults and solutions of GPS navigation instruments

1. The machine is not turned on

(1) Do not use it for a long time, do not turn on.It may be that the battery is written and protected. The connection is connected to the charger. You can turn on it. If you still can't turn on the power, please shorten the battery bipolar!

(2) The machine is not turned on (non -artificially damaged).At the beginning, you can try to press the "reset key" to revitalize the machine. If it is not good, it is likely that the machine drops the program, and the other is the key failure of the opening.

2. Click on the screen with sound but the function is useless

When the machine is used, the touch screen is not responded or inaccurate. Try to calibrate. In addition, it is likely to be the quality of the touch screen. The lines are loose. This situation occurs in winter.Chip, this problem can only be solved by the manufacturer.

3. After booting, I have been staying in the system and cannot be included in the system

One is long time, chip aging, procedure lost, and heavy brushing program.One is human operating errors, brushing the master program, and the system program in the memory by mistake when the map is upgraded. You can only brush the corresponding system software. Do not blindly brush the machine system file.brick.

4. GPS navigation cannot receive satellite signals

(1) It is useless for a long time, which causes not to search for stars.First of all, enter the map to initialize GPS, or not to accept stars, it must be the GPS module loose fake welding.

(2) You cannot find a signal or a signal for a long time.Needless to say, the GPS antenna is aging and return to the factory.

5. GPS terminal can search for satellites but cannot locate

(1) In terms of software, the map upgrade port is not modified. The download port testing software is tested, or the map owner program is not configured correctly.Some machines need to use a special version map, and a special version must be equipped.Use the GPS star search emulator with the machine itself to determine whether the hardware problem is.

(2) In terms of hardware, the machine has been exposed to the sun for a long time or works at high temperature (the machine will generate heat when working, and it is quite hot for a long time) causes the machine, GPS module, antenna to accelerate the aging, or burn directly, resulting in not searching for search.The signal or only one or two stars.

6. GPS terminal cannot recognize the memory card

(1) Software: Based on the old machine before, it does not support SD cards of more than 2G. Everyone trys to patch a patch (the system is very small).

(2) Hardware: First determine whether there is a problem with the SD card, and then check whether the SD card slot has foreign bodies, and then consider whether the card slot is damaged.

7. How to flash the machine to update the machine system version

Many G friends, I want to toss the machine and refresh the system version. First of all, we must understand the machine scheme, motherboard model and parameters (enter the settings -system information), write system information by hand, or use hand to determine the system information, or to use the system information, orScreenshots, then contact dealers or manufacturers to update the software.If you are looking online, you must pay attention to whether it is consistent with the motherboard. Do not brush it randomly, otherwise you will change your bricks.

8.GPS screen reaction is slow

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.

9.The suction cup of 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.

10.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.
