What problems happen with the navigator? GPS navigator does not see satellites


It should be noted that the lifespan of the almanac is 2-3 months, and the ephemeris is only a couple of hours. After this period has expired, data on the ephemeris and almanac must be updated. Therefore, turning off the device for a long time will cause the almanac to become outdated. Usually, after this, the navigator boots from a cold start and then operates in normal mode. But there are cases when, after a long shutdown, software failures occur that distort information and the navigator searches for a long time (several hours) and does not find its location. To bring such a device to normal mode During operation, it is recommended to leave it for several hours in satellite search mode, ensuring good visibility of the sky. A few hours of searching should bring it back to normal operation.

Attention

Quite often, motorists are faced with a problem when the GPS navigator does not see or does not find satellites. This situation can be created for several reasons, among which the most common are the following:

  • navigation almanac failure;
  • device firmware failure;
  • technical features of windshields of some cars;
  • mechanical damage or failure of the receiving antenna.

To accurately determine the cause of the loss of communication with satellites, it is necessary to carry out appropriate diagnostics. Let us consider in more detail each of the reasons for the incorrect operation of the navigator.


The navigator operates in three location modes: cold, warm and hot start. In cold start mode, the device does not have any information about its location.

Why doesn’t the navigator see satellites, and how to fix the problem?

The navigator does not pick up satellites due to a firmware failure Quite often, devices stop functioning normally and lose contact with satellites due to a failure of the installed software. To restore normal work It is recommended to reflash it. Installing newer versions on the GPS navigator will provide it with more stable work, and will also allow the use of new functionality, which were previously limited old version firmware.
Quite often, the reason that the navigator does not see or does not find satellites is the athermal device installed on the car. windshield. This glass has a special composition that can jam the signal.

  • 2 Reasons for navigator blindness
  • 3 Reinstall Navitel

Location of satellites and transmitted signal At least 24 satellites are constantly involved in the geopositioning system. They are in different circular orbits in strict accordance with the task:

  • circulation period approximately 12 hours;
  • tilt along the equatorial plane is about 55 degrees;
  • the difference in longitude between the satellites is 60 degrees.

They transmit a signal conveying the following information:

  • current time (accurate to nanoseconds) and date;
  • status (defective – defective);
  • orbital coordinates (almanac);
  • message transmission time;
  • measured aphemerides (satellite coordinates).

To determine longitude and latitude coordinates with an accuracy of several meters, a GPS navigator only needs signals from three satellites.

Can't see satellites

Info

In this case, it is necessary to reinstall the program and map information. If you have Navitel software installed, then you need to install Navitel cards. Read also: How to properly use a GPS navigator in a car? Subsequence self-installation Navitel software:

  • download a version of the Navitel program that works for your model, preferably exactly the same one that was originally installed;
  • connect the navigator to the computer;
  • download the necessary maps compatible with this version;
  • copy installation file navitel;
  • install Navitel;
  • copy the necessary maps to the USERMAPS folder;
  • restart the device.

The software installation process for some models may have its own characteristics, but the general sequence of actions is similar.

What to do if the navigator does not see satellites and what are the reasons

The comments to the maps always indicate which version of Navitel it is intended for, for example, Russia Q1 2011 for Navitel version 5.0.0.989 and higher. — Update the Navitel program, map. During the operation of the navigator, some files may be lost, destroyed or become unreadable. This leads to incorrect operation the program itself. Installing an update or simply reinstalling Navitel will solve the problem.
The navigator does not plot the route. The route is drawn as a straight line or is not plotted at all. — Restart your navigator. Sometimes it is enough to exit the navigation program and start it again. Sometimes it is necessary to perform a reset by pressing Reset on the navigator body.


— Wait for the coordinates to be determined by satellites and only then plot the route. The navigator does not load. Ie. Stuck on the screensaver. It turns on, and nothing happens beyond the splash screen. In this case, it is better to contact a service center.

Why doesn't the navigator see satellites?

Important

Almanac data is loaded from the navigator's memory, and the ephemeris is updated. Cold start 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.

Car navigator does not see satellites

Car owners often complain that the navigator does not see satellites. The reasons for such a deviation can be very diverse, for example, a violation of the device’s firmware or physical damage, resulting in partial failure of the device. When using Navitel software, users often encounter firmware failures.
You can reboot yourself. Main reasons Among the list of the most common reasons why the device may not see the satellite, the following factors are highlighted:

  • Not correct work navigation almanac;
  • device firmware violations;
  • serious damage leading to failure of the gadget.

Problems in connecting the device to the satellite may also arise due to the presence of pronounced structural features of some vehicle windshields.

Why doesn't the navigator see satellites?

In the Navitel program, select: menu - pages - satellites. On the tab the following should be selected: “GPS on” and the source “COM ports...”. It may seem funny, but very often they simply turn off satellites.
The navigator does not pick up satellites. In the Navitel program, select: menu - pages - satellites. On the signal strength scale, at least three satellites must be visible to determine the coordinates. Change your location, perhaps you are in an area with a lot of noise or in conditions where the satellite signal does not pass through (dense foliage, canopy). Positioning time up to 15 minutes. If there are no satellite signal strength bars, contact your service center. The antenna may be faulty GPS Navigator does not find satellites In the Navitel program, select: menu - pages - satellites. The geoid of the earth should have satellite icons. If they are not there, then the navigator may be in “cold start” mode.

Yandex Navigator is the main navigation development of Yandex, the leading Russian-language search engine. The application is absolutely free and can be downloaded to any smartphone running various operating systems, including iPhone (iOs 8+) and Android (3.0+). Today it is one of the most popular navigation programs among smartphone users, and, of course, many people encounter certain features and problems in using this software. Let's look at the most popular of them and try to give solutions.

So, for some reason you have Yandex navigator does not work.

Of course, the word “doesn’t work” can mean dozens of situations - from the inability to turn on the application to some difficulties in geolocation in certain regions. We will try to cover all the points in more detail, including those related to poor knowledge of the telephone structure. If you are not a beginner, you can read diagonally :)

In this article we will talk exclusively about solving problems that may arise when using Yandex Navigator. Read instructions and “life hacks” for using it in our other articles in the “Navigation” section.

Yandex Navigator does not work from the very beginning

You have the program installed, but it doesn’t open, it produces various errors, and “crashes” immediately after turning it on. It is quite possible that it was initially installed incorrectly on your smartphone.

Today, almost 100% of smartphones can work with this application, so the possibility that your phone is “weak”, has insufficient memory, etc. is practically excluded. The only exception is if the navigator freezes or works with huge delays. IN in this case we can really say that the smartphone “doesn’t work.” As a rule, this happens with devices with RAM less than 512 MB (256 MB, for example). It's really not enough.

But let's return to the first case. You just need to reinstall the program on your phone. In the smartphone settings, delete the application, go again to the place where you downloaded it (for example, for Android smartphones this is Google Market), and download it, and then install it again. If the problem was incorrect installation, then it will disappear.

You turn on the program, but it does not detect your location. Accordingly, it is impossible to either plot a route or perform any navigation-related actions. Make sure you have GPS turned on on your phone. After that, go to the window or go outside, and wait until your phone determines the satellites, and from them - your location.

Yandex Navigator is a program designed for installation on smartphones. This means that it works according to A-GPS system. This means that your location can be determined not only by satellites, but also by towers cellular communications. Those. in city conditions, you actually don’t have to turn on the GPS module, but this will cause some inconvenience when working with the navigator interface (for example, there will be a huge green circle around your location on the map, which will interfere with reading the information), and the positioning accuracy will decrease slightly.

Why Yandex Navigator does not work without the Internet

In fact, Yandex Navigator works without the Internet, but for this you need to do some preliminary actions. First of all, download maps directly to your phone, which the program will guide you through in the absence of the Internet. How to do this? Enter the application, select the “Menu” item, then “Download maps”, enter your city, and if there is a map for it, download it. It must be said that Yandex Navigator covers the space of Russia, Ukraine and many other countries very well, so there should not be any problems with finding your region.

When downloading maps, use Wi-Fi, as their size can be very large.

However, you still won’t be completely free from the Internet with this program, so in a sense, Yandex navigator really doesn’t work without the Internet. You will have maps on your phone, but to build a route or search the area you will still need network connection. The way out of this situation is to plan a route in advance, and then be truly free from the Internet while moving along this route. In any case, you will significantly reduce the amount of Internet traffic and increase the speed of your navigator.

Of course, in the absence of the Internet, Yandex Navigator will not be able to convey to you other information that may be useful. For example, about traffic jams. By the way, if the situation with traffic jams on the road is not shown, you need to click on the traffic light icon in the corner of the navigator (in given time yours is grey). After that, it will light up in one of the colors, depending on the severity of traffic jams in your city. The degree of traffic congestion is displayed with a number from 0 to 10.

The navigator does not lead along the route

Again, you first need to check if you have geodata transfer enabled. After that, check your Internet connection, including its speed (use the built-in browser on your phone, load a couple of sites). If both the GPS module and the Internet connection are active, but the Yandex navigator does not work well and does not lead along the route, then you need to close the program and enter it again. It didn’t help - go to the settings and forcefully terminate it by clicking “Stop” (for Android; the algorithm is similar for iOS), and then go into the program again. If it doesn't help, reboot your phone. It didn’t help - delete the navigation program and download it again (but, as a rule, it rarely gets to this point; after all, Yandex Navigator is a fairly stable, non-glitchy program). But let’s say even this action didn’t help. Then you need to make the difficult decision and stop using this application on your current phone. Well, they couldn't make friends. You have a choice of good analogues.

Voice search doesn't work

Here the problem could be either a broken microphone on your phone or a lack of internet connection. Another possible cause could be a noisy environment - for example, on a busy street or with loud music playing. Make sure that voice commands were heard in relative silence. In addition, Yandex Navigator, like any program, can sometimes become stubborn and not work for no reason. He will get over it, so be patient and follow the steps in the last paragraph if necessary.

Other reasons why Yandex Navigator does not work well

If your location sometimes disappears or changes, then simply re-login to Yandex Navigator. This happens sometimes, this is how the current program works.

If your path direction arrow disappears, or your phone spends a very long time searching for satellites and periodically loses them, especially if you are in long journey, then check the accuracy of the time on your phone, as well as the correct time zone. When determining your location, your phone constantly receives signals from satellites, including time information. Time must be synchronized.

Sometimes the Navigator displays a message stating that the route cannot be built because it cannot be passed. Mostly abroad. This is an imperfection of the program itself; the application is not aware of all paths. Report such cases to the developers, so together we will create a program useful for all of us. Route guidance is not available in all locations.

There are also curious reasons. For example, the navigator does not work near the Kremlin and in some other places in the center of Moscow. This is caused by security measures, or more precisely, by the work of a special transmitter that replaces the signals of real satellites.

So, we have found out the main reasons why Yandex navigator does not work on Android and other popular operating systems. Any questions and comments are welcome, we will discuss this together useful application. And, of course, follow and read our other materials in the “Navigation” section.

Mikhail Orekhov

The operating principle of navigators is based on the use of a triangulation method for determining coordinates from signals emitted by satellites. When the navigator does not see satellites, it works correctly of this device impossible. Let's sort it out possible reasons why this situation arises and what to do to eliminate it.

At least 24 satellites are constantly involved in the geopositioning system. They are in different circular orbits in strict accordance with the task:

  • circulation period approximately 12 hours;
  • tilt along the equatorial plane is about 55 degrees;
  • the difference in longitude between the satellites is 60 degrees.

They transmit a signal conveying the following information:

  • current time (accurate to nanoseconds) and date;
  • status (defective – defective);
  • orbital coordinates (almanac);
  • message transmission time;
  • measured aphemerides (satellite coordinates).

To determine longitude and latitude coordinates with an accuracy of several meters, a GPS navigator only needs signals from three satellites. Therefore, the method of determining coordinates is called triangulation. To determine altitude above sea level, a signal from four satellites is needed. If the navigator does not see satellites or finds less than three satellites, it cannot determine coordinates.

Reasons for navigator blindness

The main responsibility for the situation in which the navigator does not pick up satellites lies with the signal receiver. It may include an external receiving antenna, which amplifies the signal from the satellite before entering the receiving path. In this case there is a malfunction technical support navigator.

Possible technical problems, according to which the navigator stops seeing satellites:

  • failure of the GPS receiver circuit;
  • violation of the receiver's power supply circuits;
  • break of the communication cable with the remote receiving antenna;
  • remote antenna malfunction;
  • Incorrect location of the device in a shaded area of ​​satellite signals.

What to do to determine a specific technical reason, why Navitel does not see satellites. First of all, you need to change the location of the car. Then you should experiment with the location of the receiver or antenna in the car. The most shaded place is the area between the rearview mirror and the roof of the car. You can temporarily remove the mirror to check. If the navigator works in conjunction with an external antenna, it is necessary to check the integrity of the high-frequency cable. If the geopositioning device is not equipped with an external antenna, you can temporarily install it to check and try to pick up satellites again.

Installation remote antennas For confident reception signals are recommended in the following cases:

  • the presence of metallized coating on car windows;
  • hidden installation of the navigator;
  • installation in special equipment (for example, armored vehicles), river and sea vessels;
  • in remote areas of the far north.

The reason for the navigator to malfunction may be a memory failure, incorrect processing digital signal. Why is this possible? The navigator operates in extreme operating conditions. In the one-day operating rhythm of the device, there may be temperatures under the windshield of up to 100 degrees Celsius during the day and 100 percent air humidity in the morning, sub-zero temperatures at night and the penetration of mold into the body of the device. Sometimes for repairs it is enough to remove back cover, treat the board(s) with alcohol and heat with an industrial hair dryer. It is better to entrust such work to a professional.

Repairing the GPS receiver is the final stage of troubleshooting technical problem, according to which the navigator stops seeing satellites. Before carrying out this procedure, you must try to reinstall the Navitel software.

Reinstalling Navitel

Sometimes a malfunction of Navitel software can lead to errors due to which the navigator may no longer recognize satellites. Why this happens: software glitches change the processing parameters of the received digital signal. A situation arises in which received signal“lost” during processing. In this case, it is necessary to reinstall the program and map information. If you have Navitel software installed, then you need to install Navitel cards.

Why the inspector stops, read.

Sequence of self-installation of Navitel software:

  • download a version of the Navitel program that works for your model, preferably exactly the same one that was originally installed;
  • connect the navigator to the computer;
  • download the necessary maps compatible with this version;
  • copy the navitel installation file;
  • install Navitel;
  • copy the necessary maps to the USERMAPS folder;
  • restart the device.

The software installation process for some models may have its own characteristics, but the general sequence of actions is similar.

In order for the navigator to work without failures for as long as possible, the following operating rules must be observed:

  • protect the device from direct sunlight;
  • during long-term parking, remove the device and store in a warm, dry place, preferably at home;
  • properly organize the power bus, avoiding short-term voltage dips, which may cause search failure;
  • to increase sensitivity in areas of poor reception, use a remote antenna;
  • to prevent “clogging” the input channel with the local oscillator signal car radar detector Do not use this device in conjunction with a navigator.

Part three: Typical faults car navigators

Not long ago we called Moscow service centers serving car GPS navigators. This was done to understand what kind of support an average user can expect. It was about simple questions related to updating and installing maps. And we could only draw conclusions about the quality of service and the desire to help the motorist.

This time we decided to visit the service centers in person to talk directly with those who carry out the repairs. We found out which problems are dealt with most often, how these problems are solved and what design features that affect operation and repair are present in car navigators.

We will have to separate Garmin from other manufacturers again. The fact is that Garmin navigators are practically not repaired under warranty - in case of any serious problems, the device is replaced with a new one. This approach has its pros and cons, which we will definitely talk about. But first let's talk about Explay navigators, Digma and Lexand. The discussion of these navigators can easily be extended to other brands. Most manufacturers of navigators presented on Russian market, unifies the approach to production. Essentially, it comes down to ordering one of the models that this plant produces from one of the factories in China. At the request of the manufacturer, the case can be changed and, of course, a logo can be applied.

Inside car navigators different manufacturers may not be any different

The first question that arises is, what is the situation with quality? It was with him that we began our conversation with Andrey Antipov, an engineer at the DiCom service center. It turned out that the situation with quality is very different. And even within the same manufacturer, and sometimes within the same model. We hasten to reassure you that most navigators are assembled quite well: neat soldering, high-quality external elements, neatly connected cables, reliable housing. Contrary to popular belief, the Chinese know how to do things well. However, sometimes from one manufacturer or another, outwardly attractive devices with “internals” slip through the cracks, the quality of which raises doubts among repairmen. It is assessed visually - by how neat the boards and external elements look. It’s a pity that when purchasing you can’t ask the seller to open the device’s case.


You can evaluate the quality of the navigator by the accuracy of the soldering. But the size of the fee is not the main thing

As for the stability of quality within one model, the set of components may indeed differ from batch to batch, but situations where at first the navigator was assembled well, and then haphazardly, are rare. That's why general recommendation quite simple: study the reviews of the owners and try to make a choice in favor of proven devices, and not new products that have never been on the service engineer’s desk.

Be that as it may, navigators break down. We asked Andrey to talk about typical problems and the features of the navigators that he had to repair.

Firmware is first aid for any problems

Changing the firmware is the first thing done in the service if the problem is not obvious. In other words, when there are no obvious mechanical damages visible from the outside or when opening the case. The procedure itself is quite simple. The firmware is written to a memory card, which is inserted into the navigator. Then you need to turn on the device and, holding down the power key, wait until the screen displays information that the software is being changed. What are the nuances of this procedure?

  • Not all firmware is made publicly available. But in the service, of course, they exist.
  • Unsuccessful self-updating firmware is not a warranty case.

The most common reasons failures when updating the firmware are associated with viruses on the memory card and lack of battery power. To avoid the latter, flash the navigator while connected to external power. Moreover, it must be “correct” charger- with sufficient current and voltage. When flashing the firmware, navigators consume quite a lot of energy and weak source power supply, for example, the USB port of a computer, cannot provide the device with sufficient power. And, of course, for insurance, the navigator battery must be fully charged.

Difficulty in recovery after unsuccessful firmware depends on the situation. At best, you will need to re-install the firmware. In more complex version you have to “dump” the dump (image) from the board of a working navigator. The difficulty lies in the fact that different batches of even the same model may differ in components, which makes it difficult to select an identical board.

Separately, it is worth noting the desire of the owner of the navigator not only to update the firmware or install a second navigation program, but also to “get into” directly into the operating system Windows system CE. Almost any navigator running on Windows CE can be “unlocked” - go to the menu operating system with the ability to change settings and install programs. The meaning of this action is not very clear. Make from navigator tablet computer unreasonable. Turning off the navigator is, in essence, hard reset, resetting to factory settings everything that the “craftsman” installed on top of the operating system. Moreover, in selected models along with its own shell, which is disabled when “unlocked”, the libraries necessary for operation can be loaded navigation system. Finally, the navigator is designed to run navigation programs, and other applications simply do not have to work adequately on this hardware.


Unlocking a car navigator allows you to gain access to the standard interface of the operating system

If previous paragraph caused you a storm of indignation, then perhaps you are the right craftsman who will not be scared by either a hard reset or the need to resolve issues with the libraries necessary for Navitel to work on this specific device. In this case, we do not discourage you from experimenting, but we remind all other users that studying alternative software developer forums and abusing your navigator is most likely not what you bought this device for.

Antenna and satellite signal reception

The navigator does not pick up satellites - a fairly common symptom. However, to definitely say what caused this, diagnostics will be required. There may be several reasons:

  • firmware failure;
  • almanac failure;
  • feature of a car windshield;
  • mechanical damage or failure of the antenna itself;
  • impressive age of the device (which, however, can be attributed to the previous point).

We have considered firmware issues in sufficient detail, so let’s move straight to the second point. There are three types of navigator location modes: cold, warm and hot start.

During a cold start, the navigator does not have the slightest idea about its location, so searching for satellites takes a long time - up to 10 minutes or more, depending on external conditions. In this mode, the navigator receives an almanac and orbital parameters that allow satellites to be identified with fairly high accuracy. Then the navigator receives ephemeris - more accurate information for a more accurate calculation of the location of the satellites and the exact time.

A warm start means that the navigator has stored in its memory the almanac obtained the previous time it was turned on, and also saved time information, albeit with a small error. The signal reception time is reduced to several minutes.

Finally, a hot start - when the navigator was turned off quite recently and the almanac and ephemeris data had not yet become outdated. Positioning time can be reduced to 10–20 seconds.

The lifetime of the ephemeris is only a few hours, after which the data becomes insufficiently accurate and needs to be obtained again. The almanac's lifespan is 2–3 months.

So, turning off the navigator on long term or transporting it over a long distance with it turned off leads to the fact that the almanac becomes outdated. Usually this just means that the navigator will boot into cold start mode again, but software glitches can confuse the GPS receiver, and it will spend many hours trying in vain to find itself on the map.

This is exactly the case when the saying “time heals” works. Such a navigator must be left in satellite reception mode for a long time. Preferably where good review sky. If after an hour of being in an open space there are no desired results, then you can try leaving the navigator on the window overnight.

Quite a funny (funny for us, not for the owner of the navigator) reason bad reception satellites may be an athermal car windshield. The special composition of this glass does not allow satellite signal. However, such glass does not always interfere. Firstly, the signal can pass through the side windows, and secondly, some manufacturers provide “windows” for devices operating in the radio frequency spectrum.

The most serious reason why navigators refuse to catch satellites is the failure of the GPS antenna. With approximately the same frequency, manufacturers use antennas soldered to the board and connected separately. A soldered antenna is more difficult and expensive to replace. True, this is compensated by the fact that such antennas are less likely to fail. External antennas break more often, but they are also replaced in a matter of seconds, not counting the time required to disassemble the case. Majority external antennas are interchangeable, which greatly simplifies both diagnostics and the search for spare parts.


Most detachable antennas are interchangeable

Batteries and power from the cigarette lighter

Car navigators use the most common lithium-ion batteries. Therefore, we will outline their features very briefly. Such batteries do not like low and high temperatures, as well as full discharge. This can lead to a significant reduction in capacity and even complete failure. So, it is not recommended to leave the navigator in the car overnight and discharge it until it turns off completely.

Often the navigator does not turn on precisely for the reason deep discharge battery In this case, you need to leave it on charge overnight or even for a day. Of course, some of the capacity will be lost, but in general the functionality of the device will be restored.


The most common batteries are used.

You can keep the navigator on charge as long as you like - the controller is on motherboard makes sure that the battery is charged exactly as much as it needs. It is recommended to fully charge lithium-ion batteries, but this is not a requirement. U lithium batteries The “memory effect” is quite insignificant and can be ignored. However, if the navigator is actively used in offline mode, then at least once every 2–3 months it is recommended to do full cycle discharge-charge. Or better yet, two. It is better to use a charger from a 220 network. When connecting to a computer via USB for full charge It will take almost two days, which, you see, is not very convenient.

The peculiarity of batteries in car navigators is their short battery life. battery life. If the charge lasts for 1–2 hours, then the service center has the right to refuse to repair even a recently purchased navigator. This is due to the fact that a relatively powerful GPS antenna requires a lot of power, and manufacturers do not strive to reduce power consumption. If only for the reason that car navigator It is supposed to be constantly powered from the cigarette lighter.

There are two more features related to power from the cigarette lighter. For most navigators, only one of the two negative (side) contacts works. If the navigator “does not see” external power, then you need to try turning the cable in the cigarette lighter socket. In addition, the depth of the cigarette lighter may be greater than the power plug itself. Only finding a longer fork will help here.

Other problems and malfunctions

A problem may occur with the navigator that is not directly related to the features of this particular type of equipment. Such malfunctions include mechanical damage, failure touch screen, breaking out connectors and breaking cables.


The USB connector was broken unsuccessfully: the mounting tracks were damaged. So you'll have to tinker

So, for example, if the navigator does not respond to pressing the screen, then the cause may be a loose touch plate cable, damaged contact, or invisible damage to the sensor. If the navigator was in the cold, then the first thing we can advise is to warm it up. The glass display and plastic touch film shrink differently when exposed to low temperatures. This unevenness can cause the navigator to respond inadequately to pressing or not respond at all.


A cracked touch plate does not interfere with the display of the image. But it still interferes with working with the navigator

Features of repairing Garmin navigators

At the beginning of the article we promised to talk about the features of the repair Garmin navigators. Structurally, these navigators are not very different from those we reviewed above. But the approach to repairs in official service centers is somewhat different. The situation was commented on by Vitaly Chuyakov, a service engineer at Naviline, an authorized Garmin service center in St. Petersburg.

Most authorized service centers Garmin does not do mechanical repairs. If the problem cannot be solved programmatically, the navigator is changed to a new one. The advantage of this approach is obvious, but there is also a disadvantage. If you left warranty period, then finding an official repair center is almost impossible. And the official “paid repair” is actually the replacement of the navigator with a new one with an additional payment, often commensurate with half the cost of the new device.
