Why doesn’t the navigator turn on and show no signs of life? Possible reasons why your navigator may not turn on

Incorrect operation of the GPS module is a fairly common problem with Android devices. The system can connect to satellites, but navigation will still not work. In some cases, the defect is associated with a breakdown of the gadget’s hardware, but most situations can be resolved using software methods. Below we describe what to do if GPS does not work on Android.

First, let's determine how the navigator on the phone works. Yandex.Maps or navigation from Google contacts the system satellites and requests data about the user’s current location. Based on the information received, an optimal route is built or public transport is selected. If the GPS module stops functioning, normal navigation operation is impossible, even using A-GPS technology. The main causes of failure are usually software problems, but in some cases the source of the malfunction is the failure of a hardware module.

Geolocation services do not work on Android if the settings are incorrect. The defect may also be caused by the installation of incompatible firmware or the lack of necessary drivers.

The navigator from Google or Yandex does not work well even with a weak satellite signal. It is worth remembering that programs do not always display location correctly, and you should not rely on the system when hiking or off-road. To troubleshoot, let’s look at the causes and solutions to popular problems.

Reasons for no signal

There are two main groups of faults: hardware and software. The former can be fixed by qualified specialists in service centers, while the latter can be fixed at home.

• Hardware - a component can fail after a mechanical impact on the device body, for example, a fall or a strong blow. The cause of the breakdown may also be liquid entering the main board, followed by oxidation of the contacts.
• Software - infection with malicious software, incorrect firmware or update failures - all these malfunctions can damage the location driver.

The first thing to do if the GPS sensor does not work is to restart your smartphone and scan it with an antivirus. It is possible that the device's RAM is full and there are not enough processor resources to activate communication with satellites.

Incorrect setting

Correctly setting the smartphone parameters is the key to the correct operation of the GPS system on Android.

• If Android does not find the location, go to the device settings, then “General”, and then open “Location and modes”.
• On the Location tab, specify your preferred location method. If you select Satellites Only, Android will not use A-GPS technology, which collects data from nearby cellular and Wi-Fi networks to improve geolocation accuracy.
• Try setting the “Mobile networks only” mode and check the functionality of the cards. If navigation turns on, there is a problem with the driver or hardware.
• When GPS on Android does not turn on (the system does not respond to switching the option), there is probably a problem in the firmware. Perform a full reset or contact a service center.
• To reset your location settings, click on the “Backup and reset” tab, then tap on “Reset network and navigation settings.” Sign in to your Google account to confirm.

Important! All saved passwords from Wi-Fi access points, as well as cellular network data will be deleted.

The described method helps eliminate most problems with the software.

Incorrect firmware

The consequences of careless firmware on Android can be quite unpredictable. Installation of third-party OS versions is performed to speed up the operation of the gadget, but as a result, the phone modules stop functioning.

If you decide to reflash your device, download firmware files only from trusted forums - XDA and w3bsit3-dns.com. Do not try to flash your smartphone with an OS version from another phone, as the drivers necessary for operation may no longer function. If the device has become a brick, perform a full data reset.

• Press the volume up and lock buttons for 5-7 seconds. When the Android logo appears on the screen of the turned off gadget, release Volume Up.
• The Recovery menu will load. Select “Wipe Data/Factory Reset”, confirm Hard Reset.
• To reboot your smartphone, tap “Reboot system now”. Setup will take a few minutes when you turn it on.

The method is suitable for devices with damaged firmware. The GPS module will restore functionality after switching to the factory version of the OS.

Module calibration

In some cases, it is necessary to perform a quick calibration of the device.

• Open the “Essential setup” application, you can download it for free from the Play Market.
• Tap the compass icon and place your smartphone on a flat surface.
• Tap the “Test” button and wait 10 minutes until testing ends. Once completed, try turning on satellite navigation.

Hardware problems

Cheap Chinese smartphones are often equipped with low-quality satellite communication modules. The problem can be corrected by replacing the corresponding module at a service center. Malfunctions occur on both Android and iOS phones.

Instructions

Restoring car GPS navigators can be done in two ways: by downloading new firmware and without flashing it, using the simplest SOFT-Reset. As for the first method, everything is more or less clear here, since flashing a navigator is completely similar to flashing an ordinary cell phone, smartphone or communicator. To do this, you will need to download an archive with the appropriate firmware version from the Internet to your computer and unpack it using an unzip tool.

After this, you need to remove the memory card from the navigator, insert it into the card reader and copy the downloaded file with the firmware to the root directory. Then you should remove the card from the device and insert it back into the navigator.

Now you need to turn on the device and wait for a dialog box to appear asking whether you should start flashing. After your consent, the flashing of your car “friend” will begin. When the installation is complete, click the “Ok” button, after which a window with further instructions and directions will appear on the navigator screen. This will complete the restoration of the navigator.

Software reset of the navigator settings to the factory settings that the navigator originally had is called SOFT-Reset. To restore the GPS navigator in this way, you need to go to ResidentFlash, and then to JBSA4UI, where in the jbssetting.ini and jbssetting.ini.bak files in the DefaultSetting=0 line, change “0” to “1”.

After this, restart the navigator and go to the “Settings” - “Info” folder. At the bottom you will see 3 icons: “USB Settings”, “Navigation Path” and Werkseins..., the last of which is SOFT-Reset, that is, returning to factory settings. Click on it. After this, a message will appear: “Are you sure you want to restore factory settings?” Click Yes. After some time, the original parameters will return, therefore, your navigator will be restored.

GPS navigation is a very popular application in our fast paced life. You can easily find out your location or get directions to absolutely any destination. You can turn on the navigator on various mobile devices: PDA, navigator or phone.

Instructions

The most acceptable way to connect to navigation is to use the function directly from your mobile phone.
First, you will need the ones you need to navigate the system. Maps are available on the official websites of GPS systems for all interested users. Then go to the menu item with , select “Settings” and “Download maps”. The phone system will redirect you to the required web service. Next, choose a card for the specific region where you live.

Select Maps or Start Navigation. After some time, the first download will occur. On the KMP screen or you will see a map and your location. Then you can safely calculate distances, plot routes and destinations.

To enable this on your GPS device, you will need to enable the map page. On the menu page, highlight the “Navigation” application and select “Login.” Then highlight the “Enable Map Mode” section and click “Login” again. A page with a map will appear in front of you, on which the dot of your current location will blink. If you have problems loading, please contact the Yandex Maps or Google Maps services, since these are the maps most often used in the navigation system.

Since the device is mainly used in, you will need it on a dashboard that is convenient for you. Then attach the navigation system using the screws included in the kit. Make sure the system is connected to all necessary contacts. Most systems can be battery operated, so you don't need to connect them to the car's on-board computer. But some systems still only work when the ignition is on. So take into account all the features of the system you purchased.

A navigator is a special device that will help you navigate even in unfamiliar terrain, indicate the path on the map, commenting on it voice tips. It doesn’t matter how you travel, on foot or by car.

You will need

• - a computer with access to the Internet;
• - Garmin navigator;
• - microphone.

Instructions

Add voices to the navigator; for this, additional files can be downloaded from the official website of the Garmin program; to do this, insert the link garmin.ru/services/voice/list.php into the address bar of your browser. There is a preview of files on the page, select the one you like and download it to your computer. Then connect the navigator to your computer, go to the Garmin/Voice folder and copy the downloaded files there.

Add your own voices to the navigator. Connect the navigator to your computer, after detecting the device, go to the Garmin/Voice folder, then copy the Russkiy.vpm file to your computer. Download the NonTTSVoiceEditor application to edit the voice file from the link http://www.softpedia.com/progDownload/NonTTSVoiceEditor-Download-162575.html.

Run it and add the file you copied from your device. Parse it into several *.wav audio files, with separate words and commands to replace the standard voices navigator.

Launch the Audacity application, you can download it from the official website http://audacity.sourceforge.net/?lang=ru, to create voice prompts for navigator on one's own. You will also need the TTSVoiceEditor program to listen to existing files and replace them with your own. Download the program from here: http://turboccc.wikispaces.com/TTSVoiceEditor#TTSVoiceEditor-Download. Speak the clues into the microphone.

Each time you record, hold down the Rec button. Next, save each voiced hint with a replacement instead of the listened files. After you have completed recording prompts for navigator, compile them from *.wav files into one *.vpm file using NonTTSVoiceEditor and copy it to the Garmin/Voice folder of your device. This way you can add the voices of your loved ones to the navigator so that they can tell you the way on your travels.

There are times when you need to clean or restore your phone or tablet. This happens if you need to sell a device or give it away, or simply a huge number of applications are no longer needed. In this case, you need to reset the settings to factory settings.

Yandex Navigator is confidently among the leaders in the ranking of navigation applications for mobile devices. A side effect of this popularity is a large number of difficulties in use. Let's look at the most common complaints and try to fix them.

Unfortunately, this is very vague information, which can be attributed to dozens of reasons, including the user’s inability to run the program and real-life geolocation failures in some areas. Therefore, let's look at the situation in more detail to highlight the various aspects of the problem, and not the trivial lack of knowledge about the operation of the smartphone.

In this material we will limit ourselves to the difficulties that occur when using navigation from Yandex.

The navigator cannot start correctly

The application was installed correctly, but does not even start: it displays error messages and crashes immediately after launch. The reason may be failures when installing the program on the smartphone.

According to system requirements, almost any modern device supports Yandex Navigator, so the option with a lack of resources is extremely rare. This can be indicated by constant freezes and long pauses even before basic actions.

The smartphone may not be able to handle the application if it has less than half a gigabyte of RAM installed. For example, 256 MB is very little by modern standards.

As for the first case, you need to delete the program through the phone settings, and then re-install it. So, in Android OS you can use the Play Market. If the crash was due to an error during installation, reinstalling will fix the problem.

Why does the program need an Internet connection?

Yandex Navigator can also work if you first prepare the program for this mode. In particular, you need to download to your smartphone the very maps that will be used to display your location without access to the Internet. This can be done from the application itself. Open the “Download maps” section in the menu, then specify the required city. If you are lucky and there is a map, download it.

It is worth noting that Yandex maps on the territory of the Russian Federation, Ukraine and many other countries have very decent coverage, so there is a high probability that there will be no difficulties at this stage.

1. Before downloading, switch to WiFi, since some cards are large in size.
2. True, it still won’t be possible to completely remove the connection to the Internet, so formally Yandex Navigator really only works online.

The fact is that although the maps are stored in the smartphone, you still need a connection to plot a route and search in the immediate vicinity. To some extent, preliminary calculation of the route helps - then you can move along it without communication. One way or another, exchange via the Internet will be significantly reduced, and the speed of the program will increase.

Of course, without an Internet connection, the Navigator will not be able to download useful information, such as traffic information. Just in case, check: if they are not displayed, perhaps the traffic light image in the corner is currently gray. If so, click on it - the traffic light will be activated and will display the traffic situation in color. And a digital display is used to show traffic congestion from 0 to 10.

There is a route, but the Navigator does not track movement along it

1. First you need to make sure that receiving geodata is enabled.
2. Then check your Internet connection and its speed (for example, open a website or two in your browser).
3. If activated, the Internet is connected, but the program refuses to display the movement, try exiting the application and re-entering it.
4. If it doesn’t work, force stop it using a special button from the settings section where applications are shown (the procedure is almost the same for Android and iOS). Launch Navigator again.

If it refuses to drive again, restart your smartphone. Have you tried everything but to no avail? Reinstall the program. Although it usually doesn’t come to this, Yandex programmers have written a good application.

Let’s imagine that even such serious measures did not help. In this case, the difficult way remains is to stop using Yandex Navigator on this particular smartphone. Since it’s not destiny for them to work together, use analogues.

Voice search crashes

There are several options here:

• The microphone may be broken.
• Or the Internet connection speed is not enough.
• Or maybe the surroundings are not quiet enough - the street is noisy or the music is blaring.
• It is better not to use voice search in a noisy environment.

Well, sometimes the Navigator, like other programs, may refuse to function for no apparent reason. Wait, he will come to his senses and start working. Or follow the recommendations from the previous paragraph.

What else can cause Yandex Navigator to malfunction?

If the current position is not displayed or changes suddenly, exit the application and enter again. Unfortunately, such failures are possible.

If the arrow indicating the direction disappears, or if you search for satellites for a long time and are periodically unable to maintain contact with them (especially on a long route) check the time settings, set the correct time zone.

For geolocation from satellites The time is also transmitted, and if it diverges greatly from the system time, errors are inevitable.

Occasionally, the program refuses to plot a route, citing the complete absence of a path between points - despite the fact that there is a road and you can drive along it. More often this happens abroad. Alas, the program is not omniscient, and accordingly, routes are not laid out everywhere.

Contact the developers, help improve useful software -

And sometimes there are reasons that in no way relate to the Navigator or satellites. There are several areas in the center of Moscow (in particular, near the Kremlin) where the application does not work. But this is not a mistake, but the foresight of the security services: special transmitters for the protection of strategic objects interrupt the satellite signal, giving out deliberately incorrect data.

Conclusion

In the article, we looked at the main reasons that can lead to Yandex Navigator failures, whether on Android OS or another system.

Add your questions and comments about the program, we will discuss the features of its work with the whole world. Good luck on the road!!!

Many motorists are faced with a problem when the navigator does not see satellites. Several reasons can lead to such a situation - a failure of the almanac, the composition of the car glass, a software failure and a breakdown of the receiving antenna.

Almanac failure

Most often, the navigator does not see satellites due to a failure of the navigation almanac. The fact is that the location of the device can be determined in three ways: hot, warm and cold start.

If the device was recently turned off and then turned on again, a hot start is used. Typically it takes about fifteen seconds to find satellites. At the same time, information about the almanac and satellite orbits is stored in the device’s memory, which allows you to return to work in a short period of time. Also, the navigator does not need to request the ephemeris.

Warm start means turning on the device in two to three minutes. Almanac data is loaded from the navigator's memory, and the ephemeris is updated.

The longest is about ten minutes. The navigator has no information about its position in space. First, the device receives an almanac, and then ephemeris, which allows the satellite’s orbit to be most accurately determined. Navigators with traffic jams still need to connect to the Internet (this takes about one minute).

It is noteworthy that the almanac data does not lose its relevance for several months. Ephemerides “live” much less - two to three hours. When the above deadlines expire, the information needs to be updated. After this, the device boots into cold start mode and works quite normally. However, there are times when the almanac gets confused and the navigator does not see satellites for up to several hours. In this situation, you need to place the device in an open space and leave it in that position. After some time it will return to normal operation.

Composition of automobile glass

By the way, the navigator does not see satellites on those cars where it is used. It has a special composition that screens the signals. The solution to the problem is to install the device near a special area for transmitting signals, located on athermal glass.

Software failure

In some cases, the navigator does not see satellites due to a software failure. To fix the problem, you need to reflash the device. Branded car navigators - "Garmin", "Navitel", etc. - can be updated on the manufacturer's official website. For Chinese devices, software is more difficult to find, but still possible. Remember that you only need to flash the device with a fully charged battery!

If you are not so competent in replacing software, then take the device to a service center, where specialists will carry out flashing for a small fee.

Receiving antenna failure

This is the most serious reason for loss of communication with satellites. By the way, navigators use two types of antennas - external and soldered. Replacing a soldered antenna is more expensive than replacing an external one, but such devices break down much less often. Replacement can only be made at a service center.
