Many car owners are faced with a situation where the standard navigation in the car no longer correctly displays new junctions or roads built last year. This is especially true for owners of Chinese Android recorders, where the pre-installed version of the software often becomes outdated even before purchasing the device. Updating maps Navitel is not a complicated process, but it requires attention to the details of the file system and kernel versions.
There are several ways to update the data: through the built-in update center, manually downloading files from the official developer portal, or using third-party utilities to generate atlases. The choice of method depends on the specific model of the head unit, the version of the operating system Android and the availability of Internet access directly in the car. We will look at a universal manual installation method that is suitable for 90% of devices based on Android.
Before starting the procedure, it is critical to understand the data storage structure on your device. Unlike personal computers, the file system of the radio may be hidden from the user or have specific access rights. Incorrect placement of atlas files will result in the app simply not seeing new maps, despite their presence in memory.
Preparing equipment and checking the current version
The first step is to diagnose the current state of the navigation software. You need to go to the app menu and find the “About the app” or “Information” section. Here we are interested in two parameters: the application version number and the date of the last map update. Write down this data, as they will be needed to select a compatible update package on the server.
To carry out the procedure, you will need a personal computer or laptop with network access, as well as a cable USB type Male-to-Male (two type A plugs) or a memory card MicroSD. Using a memory card is often preferable, as it reduces the risk of damaging the file system of the internal memory of the radio if the cable is accidentally disconnected.
Make sure that there is enough free space on your device. Modern regional maps can take from 2 to 10 gigabytes, depending on the level of detail and the number of loaded layers (traffic jams, cameras, 3D buildings). If internal memory is small, consider transferring the cache to external media through the app settings.
⚠️ Attention: Before copying new files, be sure to back up the folder
NavitelContent. If the new version of the maps turns out to be incompatible with your app core, you can quickly roll back the changes and restore navigation functionality.
Check the formatting of the data carrier. Radios based on Android work correctly with the file system FAT32. If your flash drive is formatted in NTFS or exFAT, the device may simply not see it. To change the format, use standard Windows tools, remembering that this will delete all data from the media.
☑️ Preparing for the update
Downloading updates from the official portal
The most reliable source of up-to-date data is the official website of the developer. Go to the downloads section and log in to your personal account. Even if you are using a free or trial version, base maps are often available for download without being tied to a license key, but activation may be required for full functionality.
In your personal account, find the “My Devices” or “Updates” section. The system will automatically determine suitable packages, but it is better to select a card manually by indicating your region. Please note the file format: manual installation usually requires an archive .zip or .rarcontaining files with the extension .nm2 or .nm3.
Downloading large amounts of data may take time depending on the speed of your Internet connection. It is recommended to use a download manager, which allows you to resume the process if the connection is lost. After the download is complete, do not rush to unpack the archive onto your desktop.
Use a browser with a built-in ad blocker when visiting third-party forums on radio firmware to avoid accidentally downloading malicious executable files instead of cards.
It is important to distinguish between the updated files of the app itself (executable .apk) and files maps (atlases). For the purposes of this article, we focus specifically on maps. Updating the application itself Navitel Navigator should be performed separately if the current version does not support the new map compression format.
| File type | Extension | Purpose | Where to store |
|---|---|---|---|
| Executable file | .apk |
app installation | Memory root or Install folder |
| Map file | .nm2 / .nm3 |
Navigation data | NavitelContent/Maps |
| Atlas file | .atlas |
Card index | NavitelContent/Maps |
| License file | .nlf |
Region activation | NavitelContent/License |
Folder structure and correct placement of files
The most common mistake users make is incorrect location of files in a directory. The app Navitel strictly follows a certain hierarchy. When you connect the radio to a PC in storage mode (MTP) or after removing the memory card, you should see a root folder with the name of the application.
Inside the root directory NavitelContent there should be several subfolders. The key one for our task is Maps. This is where you need to place the downloaded map files. If the folder Maps is not present, create it manually, respecting the case of letters (uppercase and lowercase letters matter in Linux-like systems on which Android is based).
In addition to maps, there is a directory Licensein the folder structure. License files are placed here if you have purchased additional regions. There is also a folder Tracks for downloaded tracks and Skins for themes. Do not mix files of different types, otherwise the indexing algorithm will generate an error when launched.
Directory structure:/NavitelContent/
/Maps/ (put .nm2, .nm3 here)
/License/ (put .nlf here)
/Skins/ (themes here)
/Voices/ (voice packages)
After copying the files, safely remove the device from the computer. Do not pull out the cable abruptly, as this may damage the file system partition table, which will lead to the need to completely format the radio drive.
What to do if the NavitelContent folder is not visible?
Sometimes on Chinese radios, access to the internal memory is limited. Try using a file manager installed directly on the radio (for example, ES File Explorer or Total Commander) to create the desired folder structure manually inside the device.
Indexing process and first launch
After installing the files in place, launch the navigation application on the radio. When you first start after the update, you will see a message about searching for maps or the indexing process. At this point, the app scans the contents of the folder Maps and builds a search index for quick access to addresses.
This process can take from a few seconds to several minutes depending on the number of loaded regions and the speed of the processor of your head unit. On older models with single-core processors, indexing a detailed map of the entire country can take up to 5-7 minutes. Do not interrupt the application at this time.
If indexing was successful, you will be able to select the map in the “Atlas” menu. Make sure the checkbox is next to the desired region. If the map is grayed out or cannot be selected, it means that the file is damaged or the format of the map version is not supported by the current app core.
⚠️ Attention: If after updating the app crashes when trying to build a route, there may be a version conflict. Try removing all maps and leaving only one region to check the system's functionality.
Check whether the current location is displayed correctly. Sometimes after the update the settings of the GPS receiver are lost. Go to the navigation settings and make sure that the correct coordinate source is selected (usually the built-in Android GPS module, and not an external Bluetooth receiver if you do not use it).
Successful indexing of maps takes time and depends on the power of the radio processor; interrupting the process may result in the need to rescan all files.
Solving common problems and activation errors
Users often encounter the “Invalid card” error or the requirement to enter an activation key, even for free cards. This happens if the license files .nlf are missing or in the wrong folder. For free versions, you sometimes need to create an empty license file or use a special patch, depending on the software build.
Another common problem is the lack of voice. After updating the maps, voice packets may be lost. Go to the sound settings and select the speaker again. If the voice is not in the list, download the voice package separately and place it in a folder Voices, observing the subfolder structure required by your version Navitel.
There are cases when the radio does not see the memory card after the update. This may be due to a change in the mounting path of the drive in the system Android. Try changing the path to maps in the app settings, specifying a new path to external storage, which often looks like /storage/sdcard1 or /mnt/external_sd.
How to reset Navitel settings to factory settings?
If nothing helps, go to Phone Settings -> Applications -> Navitel -> Storage -> Clear data. This will delete all settings and maps, returning the app to its original state.
For advanced users, it is possible to edit the configuration file navitel.ini or settings.ini. There you can register hard paths to maps, which eliminates automatic search errors. However, editing text configs requires caution and understanding of the syntax.
Alternative methods and updating via Wi-Fi
Modern versions Navitel Navigator support updating maps directly via the Internet. If your radio is connected to Wi-Fi (for example, via sharing from a smartphone), you can try using the built-in update center. This method is simpler, but requires a stable connection and sufficient traffic.
To start automatic updating, go to the “My Navitel” -> “Updates” menu. The system will check the available packages and offer to download them. The advantage of this method is that the app itself will download files of the required format and place them in the correct directories, minimizing the risk of user error.
However, this method has a significant drawback: the built-in browser or bootloader on Chinese radios is often unstable. The download may be interrupted by 90%, which will result in downloading a broken file. In this case, manual updating via PC remains the most reliable option.
⚠️ Attention: When updating via Wi-Fi, monitor the car's battery charge. Long-term operation of the navigation and Wi-Fi module with the engine off can drain the battery if you do not have a voltage monitoring system.
Some users prefer to use third-party card assemblies, for example, from the community 4PDA. Such maps often contain more detail and are updated by enthusiasts faster than official ones. However, installing such cards requires unlocking the bootloader or using modified versions of the application, which may violate the software warranty.
If you use automatic updating, set it to work only via Wi-Fi so as not to accidentally use up your mobile traffic limit when distributing the Internet from your phone.
Why does the radio not see the map files after copying?
Most likely, the files are in the wrong folder or have the wrong extension. Check that the files are located in NavitelContent/Maps, and not in the root of the flash drive. Also make sure that the files are not blocked by the “Read-Only” attributes.
Is it possible to update Navitel on an old version of Android 4.4?
Yes, but the functionality will be limited. New versions of cards may require a more recent app kernel, which is not supported by older operating systems. In this case, it is better to stay on the latest compatible version of maps for your software release.
What to do if all route settings are lost after the update?
When updating maps, the settings may be reset. You will need to re-set preferences for the type of roads (avoid toll roads, unpaved roads), select units of measurement and voice prompts in the app settings menu.
How to free up space on the internal memory of the radio?
Delete old versions of maps, cache of unsuccessful downloads and unnecessary music files. Transfer heavy atlases to a memory card MicroSDby changing the path to them in the navigator settings.
Is it safe to download maps from torrent trackers?
This carries risks. The files may be modified and contain malicious code that can steal data or damage the device. The official website is the only guaranteed safe place to download software.
