The texet navigator is not detected by the computer. Why doesn't the computer see the navigator? Detailed information on how to quickly connect your navigator to your computer
25.08.2009, 21:55
Good day to all. I recently purchased Texet TN-505. Problem when connecting to a PC: it can only be seen via ActiveSync but not as a USB drive. Has anyone encountered such a problem? Help. Thank you in advance.
01.10.2009, 15:57
I have the same problem, what should I do?
08.10.2009, 13:49
but not as a USB drive.
This happened to me after using AMIGO. This program kills SD memory cards.
If the device was turned off at the time of recording to the memory card.
Try turning on your memory card through the card reader. If it is not visible there, then try to check using Windows with error correction enabled.
Or format it with the FAT32 file system. I got a 4 GB Kingston card. I also bought Sandisk 4 GB and it also started to glitch - I can’t see any records on the disk. The next day the card came to life. When I demolished AMIGO, these problems disappeared, although the card contains IGO8.0, IGO8.3 "Avtosputnik" and more.
PS And Kingston could not be restored.

As a flash - he sees that you need to rearrange the point on the USB in the settings menu of the shell itself, the one that loads automatically;)

I’ll probably join the question, since the programs haven’t been installed yet, but I can see them in the settings menu via MS ACTIVESYNC, but not via USB. I would just like to quickly use the internal memory (4GB). Yes, and since the navigator has such a function, I think that it should work for anyone. Dear gurus! where is the problem, how to fix it? Tell me please.
11.01.2010, 14:22
Apparently no one knows what this problem with the navigator not being detected is? I have a Pioneer PI 685 - it doesn’t see it at all. I do not know what to do. I contacted the guys from the online store, they are the same :(
18.02.2010, 18:41
The same nonsense. The OODO 5006 navigator, the first time everything was fine, showed everything that was on the flash drive. Now the computer shows the device is not identified, and what should I do, otherwise I don’t really want to use the card reader every time???
20.02.2010, 20:10
And mine doesn’t see it, neither as USB nor via ACTIVESYNC
15.08.2010, 23:09
so that Windows can see the navigator >>> task manager - off. or delete the navigator that was not installed correctly with the sign (!) - then turn it on again. and if it doesn’t install, update the driver.
30.09.2010, 13:53
If none of the above helps, connect the navigator with the ORIGINAL wire (5 wires), and to the back panel of the computer where the USB cables come from the motherboard. fees.

Thanks for the advice, none of them help...((neither active sync nor as it seems (

It's Windows 7 and Windows_Mobile_Device_Center_v6.1_32-bit doesn't connect, it's a problem I don't know what to do :(
And who will read and follow the rules?
20.11.2010, 19:23
I apologize, I have a mappy iti400n navigator, Windows CE 6.0, apparently it costs some kind of igo, there is mappy.exe and the icon says amigo, in general, I connected my PC (Windows 7 32bit) with the navigator for 3 days via Windows_Mobile_Device_Center_v6.1_32-bit, yesterday it was successful, I installed it total commander in Navi, then opened the control panel - usbclientswitch selected serial class and everything connected :)

Hello! Please tell me the navigator MYSTERY MNS-350MP (V1GO7) when connected to a PC is defined as USB GENERIC, and requires installing a driver, but the installation disk was successfully broken, the active synch device does not find that it has some kind of special driver, or I have the device itself broken? The navigator starts, but Navitel does not see it on SD, and the navigator icon is not active: (On the Mystery website there is no answer from the representatives to the question I asked.

At first my actvsync saw the device. And after viewing the win ce functions using total commands, it stopped connecting: (.it connects and then disconnects. When you switch the device to the memory card, the computer sees 2 flash drives (removable and internal). Maybe flashing the firmware will help? Just which one for me? I don't know if it will fit?
I have one - no name, win ce6
17.03.2011, 19:56
When I connect the Navik to my computer as an activesync, a connection window appears, so I accidentally pressed the cancel button. As a result, the computer writes an unknown USB device, disconnected, reconnected, changed modes, all to no avail. What to do?
17.03.2011, 22:34
You take the same animal, go to ResidentFlash2, copy the folder there that contains the USB drivers (AND MUCH MORE), copy it to ResidentFlash2 and everything works.
It is advisable after this to do a reset to the factory settings, the Navik will turn off and on, I do this all the time, today I was restoring the functionality of the animal, there was a problem with the shortcuts, they were deleted and connected poorly, that is, there is no connection with the BB

gemuch,
If it connects steadily like a disk, then don’t worry, otherwise you’ll have to ask even more questions later if it works, something’s wrong with the firmware.
18.03.2011, 11:51
Thanks for the advice. The solution turned out to be simpler; after restarting the computer, everything connects.

Hello, I have a similar problem, I have an Explay 985 Win CE6, when connected to a computer, it sees two disks, and it opens the flash drive, but there is no resident memory. I turned on Total Commander and tried changing the USB settings in the control panel. No result. Now on many Naviks there is such a thing - there is no access to the built-in memory. (I've seen a lot of navigators, I sell them myself) :pardon:

Navigator GOCLEVER Navio 500 plus
(Win CE 5.0, MediaTek processor, internal ResidentFlash memory, external SDMMC)
The navigator is new, when connecting to the PC for the first time, it turned out that the size of the internal memory is not 2 GB, but only 172 MB. I tried to format it from PC to Fat32, FAT, NTFS - to no avail. Writes: "Windows cannot be formatted." Disconnected from PC, then connected again. After this, it is not possible to access residentflash and sdmmc not from a PC or from the internal menu of the navigator.
There is access via Active Sync: I see Windows files and an sdmmc memory card.
Are there any ways to solve this problem?
07.06.2011, 07:32
sid-brest, for such matters it is better to use special utilities for proper formatting, they are on the forum, and whoever looks for will find;)

25.10.2011, 16:55
Windows 7 is still a very crude system and there are a lot of problems with the correct installation of drivers. I returned to xp then it worked on the seven, it didn’t work out no matter how hard I tried.

Tell me how to connect Explay ST4 to a computer. The standard shell (MStarApp) when connecting usb, offers the choice of charging or usb disk, but I don’t want to use it. Is it possible to somehow configure Navik to connect either through the mobile center or as an external drive? There is no usb mode selection in the control panel, I tried to create connections manually, changed the driver function value in the registry, nothing works, and in general, if you do not start the standard shell (MStarApp), the device is displayed in the manager as unknow device

Good day everyone! :-) Not long ago I encountered a problem - the computer stopped seeing the navigator-Texet TM650 A5 altogether. Until some time everything was just fine, I connected and did what was necessary both on the flash drive and on the internal memory of the Navik, by the way not the worst model... because he suffers so much “bullying” from me... I don’t know what comes into my head))))) Well, it all ended (I hope temporarily) after I took His navigator from a friend. ..it seems Prestigio I don’t remember the model, I tried to connect and someone’s computer glitched, I had to reboot. Subsequently, the computer started working, but nothing with the Naviks. What could it be?? The navigator works without problems, but there’s no way to get into the internal memory, flash drive card reader no problem...it’s not interesting)))))

There are Chinese Naviks like pioneer Atlas V win CE 6.0, I can’t connect to the computer, there are no settings for the connection type in the menu, I tried changing the connection method from winCE itself (the default was none) and mass_sotage and activ_sync, it doesn’t help at all, I tried cables different, naviki too, zero result. What else can you do?

Tell me if there are any general principles for connecting an external GPS module to navigators for CE. How can I make the navigator take “information” not from its own internal module, but from an external one?
18.07.2013, 13:34
The problem is this: I used this miracle. And one day it stopped being detected by the computer (not just mine) in any of the modes. I've already tried changing the data cable, but it's useless... Maybe someone has figured out where to go? The warranty has expired. Or, at least, how can I see the desktop on it? Otherwise you need to install the software, but there’s no way through the path to the navigation program. Thanks in advance
You can use TotalCommander under WinCe, i.e. run it through the path to the navigation program and configure everything.

My Windows 7 stopped seeing the navigator. Displayed as a Usb mobile device, which made no sense "0". Solved during the installation process of Mobile Device Center. It's in the process. I didn't run the program either. While it was just being installed, I noticed some movement in the tray (in general, he liked some driver) and then the “GPS system” icon appeared in “My Computer”, clicking on it, I saw my desired “Disk” and “Resident Flash ".
P.S.: Before starting, remove the standard "Synchronization Center" for Windows, otherwise it will not accept the older version of Mobile Device Center.

Recently I encountered a problem - the computer does not see the navigator. Prology navigator. I tried all the USB ports - it doesn’t see it and that’s it. I have a printer and mouse connected to USB ports. I turned everything off, connected an old mouse to the PS2 port, connected the navigator to USB and the computer saw it. I updated the firmware and cards, in short, everything is fine.
It turns out that the mouse was in conflict with the port to which the navigator was connected.
Here, try it, maybe it will help someone.

Hi all.
The PC does not see Navik,
a couple of days ago the splash screen was on after turning it on, I took it apart, entered the service mode, connected it, did not flash ANYTHING, disconnected it from the PC, turned on the Navik and it worked, the USB worked and everything seemed to be fine.
Today it no longer connects, I tried it in different ways through the service effect - 0.
The Navik itself works, charges from a PC/socket, picks up satellites and everything is buzzing. But I can’t access it via USB, the PC doesn’t see it and that’s it.
Who came across it? 912M v2.2

You can often come across the question “why?” The computer does not see the Explay GPS navigator? It is impossible to answer this question right away, but we know how we can help your problem. Of course, it all depends on the reason. Our service center offers you testing, diagnostics, repair and maintenance of your device. We work with any models of Explay navigators pn 990, pn 980, pn 970, pn 935, pn 930, pn 925, pn 920, pn 445, pn 430, pn 375, GN-510, etc. Qualified specialists will work with your device. Our service center cooperates only with suppliers of original spare parts and works only with licensed software. We will diagnose and cure your X-play as soon as possible. And rest assured in the quality of our services. You will be pleasantly surprised by the quality-price ratio.
Let's look at possible problems that can answer the above question. If the computer does not see the Explay navigator, then first of all we advise you to pay attention to the USB cable with which the Explay is connected to the personal computer. If there are obvious signs of damage on it, then most likely the cause of the problem is in it and it should be replaced. To be sure that the problem is in the cord, we suggest you try connecting to the PC with other cords.
If the malfunction continues, then it is possible that Windows does not see the Explay navigator on the PC due to a problem in one of the USB ports. They can be broken, both on the system unit of the personal computer and on the navigator itself. It is worth trying to connect the device to another port using a working cord. If the ports in both are working, then device incompatibility can be considered as a possible problem. We advise you to download software and drivers from the manufacturer's official website.
If the Explay navigator still does not connect to the computer, then perhaps the problem is a malfunction of the operating system of your personal computer. Try reinstalling it, installing a different version or a different OS altogether. The software may be conflicting with the OS.
If the cause of the breakdown is the inoperability of the port, then our technicians will easily and quickly replace it, and you will continue to enjoy the functions of your device. We strongly recommend that you contact us if Explay navigator is not detected by the computer. After carrying out the diagnostic and testing procedure (the service is free), our specialists will determine the cause and essence of your breakdown and, if you wish, will help with its solution in a short time and at an affordable price.
Also, the computer does not detect the Xplay navigator when it is connected with a low battery. It is likely that your personal computer does not see the GPS receiver due to mechanical damage or water or any other moisture getting inside the device. Problems with the firmware should be considered as one of the options leading to the computer not finding the Explay navigator. Then the receiver needs to be reflashed. We strongly recommend that you contact a service center for this service rather than performing it yourself. Self-medication can greatly damage the device.
We also often come across the question “Why doesn’t the Explay navigator see the flash drive?” Make sure that the flash card is correctly installed in the flash reader and there is no obvious mechanical damage. A common reason that Xplay does not see the memory card is a malfunction of the memory card itself. Try inserting another flash drive and see if it works. If the Explay navigator still does not see the memory card, then most likely the reason is a broken flash reader.
Today, one of the most accurate devices that enable a person to navigate the terrain are GPS navigators. Today we will tell you how to connect a navigator to a computer on your own. Their main purpose is to receive a signal from a satellite, and due to the presence of special programs built into the navigator, they are simply irreplaceable for determining their location.
Detailed information on how to quickly connect your navigator to your computer
- To connect your navigator to your computer using a USB cable, you must connect the cable to the navigator.
- Turn on the navigator.
- Usually the computer is able to automatically detect a new device. If this does not happen, you should install the software that is sold complete with the navigator.
- Once the computer has identified the navigator, you can begin copying files from one device to another.
- After copying files is complete, disconnect the cable.
- While holding the “Start” button, turn off and then turn on the navigator.
- The above steps describe the steps to connect the navigator to a computer, Treelogic line. Things are more complicated with GARMIN series navigators; in this case, you will have to work with a soldering iron. This navigator is connected to the COM port of the computer using a 9-pin connector. To connect the navigator to the computer, you should use a three-wire cable: one wire is ground, the second is used to transmit data, and the third is used to receive data.
- We clean all the contacts and wires necessary for soldering.
- Solder the wire transmitting data to the contact of the second nine-pin COM connector.
- After this, you should solder the wire that receives all the information to the contact of the third nine-pin COM connector (or to the contact of the two and 25-pin one).
- The third wire (“ground” of the cable braid) must be soldered to the fifth pin of the nine-pin COM connector (or the seventh pin on a 25-pin one).
- Next, connect the already soldered cable to the COM port of your computer.
- Turn on the navigator.
- After completing the data exchange, turn off the navigator, and then disconnect the cable.
Hello, dear car enthusiasts!
As a rule, after purchasing a car navigator, you need to connect it to a computer and update the maps installed at the factory and outdated at the time of purchase.
In my case, the situation was with the Prology iMap-552AG+ car navigator and the Navitel navigation system installed in it.
Following the instructions, I downloaded the latest version of the map of Russia from the official Navitel website. Next, I needed to connect the navigator to the computer via a USB cable and replace the outdated card with a new one, but the following problem prevented me from doing this.
The computer does not detect the navigator
In the navigator, as required by the instructions, in “USB Settings” I chose that when connected to a computer via a USB cable, the device would be defined as a removable disk, i.e. I activated "Internal memory".
The next step, the step in which I failed, was the operation of connecting the navigator to the computer via a USB cable, the latter being an Acer laptop. When connecting, Windows issued a warning “The device is not recognized and will not work correctly,” therefore, the new removable storage device did not appear in “My Computer” and it was not possible to update the cards.
Having made more than one connection attempt, which involved using different USB ports, rebooting devices and re-reading instructions, I still did not achieve the desired result and turned to the Internet for help. But, unfortunately, failure awaited me here too. My navigator appeared on the market not so long ago and did not have time to be discussed on the forums.
Out of despair, I could only use the “scientific poking” method. As they say, patience and hard work will wear out everything, and after many connection attempts, I began to draw conclusions that the problem is not the lack of drivers for the navigator in the system, but the incompatibility of devices?!
At that moment, I had hope, which was pinned on a second, older desktop computer.
Looking ahead, I will say that my hope was justified. I managed to connect the navigator to the computer as a removable storage medium and carry out the subsequent stages of updating the maps. The problem with the connection was in a place completely uncharacteristic for such devices!
The problem, to my surprise, was that the modern car navigator did not support connecting to a computer via a USB 2.0 port, of which there are already four on the laptop. Therefore, to update the navigator, I needed another computer with a USB port version 1.0. It turned out to be an old faithful friend - a desktop computer, with the help of which I updated the navigator maps.
P.S. Another thing I found out during the process of connecting and updating maps is that you only need to connect the USB cable to a switched on and fully infected navigator, this will avoid “freezes” and “brakes” of the device.
We often hear from our users the phrase “For some reason, my The computer does not see the Prestigio navigator" Let's figure it out together. There can be many reasons for this and at first glance it is almost impossible to make a diagnosis. We will help you with diagnostics, testing, prevention and repair of almost any model of Prestigio GEOVISION 5500, 5300,5200, 5120, 4300, 4200, 4120,5300, 3200, etc. We employ only qualified personnel who will bring your device back to life.
Below we will try to consider the main causes of this problem. To begin with, we suggest you pay attention to the USB cord with which the Prestigio is connected to a personal computer. Perhaps this is the reason. Inspect for any external damage or kinks. To control, try connecting the receiver with other cords.
Why doesn’t the computer see the Prestigio GPS navigator even when connected with a whole cord? Perhaps the problem is in the USB ports and therefore the Prestigio navigator is not detected by the computer. They may be faulty both on the PC and on the device itself. Try connecting the receiver to other USB ports on your computer. If this does not help, it is worth diagnosing the navigator.
If both the ports and the cord are intact, a possible reason for the incorrect operation may be incompatibility of the devices. We advise you to download the latest software and the latest drivers from the manufacturer's official website to check. It is possible that the whole problem lies in the operating system itself and the computer does not find the Prestigio navigator. Try reinstalling it. We prefer Linux OS, as it is much more productive and reliable than others.
If the main problem is a non-working navigator port, then our specialists will quickly and efficiently replace it. After diagnostics and testing, we can accurately say why the Prestigio navigator does not connect to the computer, and, at your request, we will help eliminate the cause of the breakdown. We guarantee the quality of the services we provide and therefore we recommend our service center to you. Also, on a PC, Windows does not see the Prestigio navigator if you connect it with a completely discharged battery. It is likely that the personal computer rejects the Prestigio due to mechanical damage or water or any other moisture getting into it.
Maybe the computer does not detect the Prestigio navigator due to problems with the firmware or software of the receiver. Of course, there is a lot of information on the Internet on how to reflash the navigator yourself. But we strongly recommend contacting the service center for help, since inept handling can lead to irreparable consequences.
We are also often contacted with the same problem: “The Prestigio navigator does not see the flash drive.” Check to see if you inserted the USB flash drive into the device correctly. Pay attention to whether there is any external damage. Often the reason is that Prestigio navigator does not see the memory card, is precisely its malfunction. Try inserting another flash drive and see the result. If he still remains inconsolable, the reason may be a broken flash reader. In any case, diagnostics are needed. We produce it absolutely free of charge. And if the problem with the flash reader is confirmed, then our qualified specialists will replace it with an original one as soon as possible. We do not advise you to try to repair your navigator yourself, as this will most likely lead to irrevocable death, so it is better to seek help from a workshop.
