Owners of cars equipped with universal multimedia systems based on Androidare often faced with the need to find out the exact model of their device. This becomes critical when updating firmware, searching for drivers, or troubleshooting software glitches. The market is dominated by devices from Chinese OEM manufacturers, who often use the same cases for completely different “fillings.”
The front panel of the radio may have a beautiful brand like Teyes or Pumpkinon it, but this is just a marketing name. Inside is hidden a hardware platform from factories like Xtrons, Topway or XY Auto. It is this hidden information that needs to be found so as not to turn the device into a “brick” when trying to flash it.
There are several levels of identification: from simple viewing of settings to in-depth analysis of system files through the console. In this article we will analyze all the methods - from the simplest for beginners to advanced ones that require connecting a keyboard or laptop.
Checking the “About the system” section in the settings
The most obvious and safest way to start the search is in the settings menu of the head unit itself. However, as practice shows, the information here is often incomplete or intentionally hidden by the manufacturer. You need to go to the section Settings and scroll down the list to the item About device or About system.
This section usually displays version Android, build date and model number. But be careful: many budget Chinese radios replace real data. For example, instead of the actual processor, the name of a popular higher-end chip may be displayed. However, you can often find a field here MCU Version (microcontroller version).
Write down this code in full. A line like XY-AS-MTCD-1.0.5 or K2-MCU-20210512 contains the clue. The prefix (for example, MTCD or K2) indicates the platform on which your radio is built. This is more important than the brand name on the box.
⚠️ Attention: If in the “About Device” menu the MCU or Model fields are empty or display “N/A”, then the manufacturer has blocked access to this information at the software level. In this case, proceed to the following methods.
Sometimes the necessary data is hidden in a hidden menu, access to which is opened with a special password. Try to find the item Factory settings (Factory Settings). When pressed, the system will ask for a code. Popular combinations include 8878, 1234, 3368, 0000 or 123456.
Analysis of factory settings and access codes
Getting into the menu Factory settings opens access to technical information that is not visible to the average user. The type of radio chip is often indicated here (for example, RDA, NXP or TDA), which indirectly helps to determine the series of the device. But the main goal is to find a tab with information about the system.
Inside this menu, look for lines starting with System Version or Firmware Date. Often the platform code is written there, such as MTCE, MTCP or K2. These abbreviations are the de facto standard for classifying Chinese 2DIN radios. Knowing the platform, you can find the appropriate forum or support group.
- 🔍 MTCD/MTCE —popular platforms based on MediaTek processors, often found in models in the mid-price segment.
- 🔍 K2/K7 —platforms based on Rockchip processors, characterized by stability and good compatibility with the CAN bus.
- 🔍 XY Auto —one of the largest OEM manufacturers, whose devices are sold under a hundred different brands.
If you have found the platform code, enter it into the search engine along with the phrase “firmware” or “firmware”. This will most likely lead you to resources where the latest updates specifically for your “stuffing” are located, regardless of the sticker on the case.
Write down all the found version codes on a piece of paper or take a photo of the screen before any manipulations. This is your insurance in case of a factory reset.
Installing applications for system diagnostics
When the built-in settings are silent, third-party utilities from the store come to the rescue. Google Play. There are a number of specialized applications developed by enthusiasts specifically for diagnosing Android car systems. They are able to read information directly from the system core.
One of the most effective tools is the application Car Info or Device Info HW. Once installed and launched, these apps scan the hardware and provide a detailed report. You should be interested in the sections SoC (system on a chip), RAM (RAM) and Screen Resolution (screen resolution).
The data obtained allows you to narrow down your search. For example, if the application shows a processor Rockchip PX6 and 4 GB of RAM, you immediately cut off all budget models by Allwinner. This is critically important, since firmware is incompatible between different processor architectures.
| Application | What it shows | Complexity | Requirements |
|---|---|---|---|
| Device Info HW | CPU, GPU, sensor details | Low | Internet access |
| AIDA64 | Full spectrum iron | Medium | No |
| Car Info | Special. data for auto-GU | Low | No |
| CPU-Z | Information about the processor and memory | Low | No |
Remember that Some radio manufacturers block the installation of applications from unknown sources. If you cannot download the application directly, you will have to download .apk the file to a USB flash drive and install it manually through a file manager.
⚠️ Attention: App store interfaces in car versions of Android are often cut down. If you do not find the required utility in the search, use the browser on the radio to download the APK file from a trusted resource.
☑️ Preparing for diagnostics through applications
Physical inspection and markings on the case
If software methods do not give an unambiguous answer, you will have to resort to “physics”. This is the most reliable method, since the stickers on the board will not deceive you with marketing gimmicks. To do this, you will need to carefully remove the radio from the car's dashboard.
Usually the head unit is mounted on a metal slide using spring latches or screws. Use special puller keys, which are often included, or thin metal plates. Be extremely careful not to scratch the plastic of the dashboard.
After removal, inspect the top housing cover. There should be a silver or white sticker with a barcode. Look for lines Model, PCB Version or Serial Number. Often the type code XY-AS-8227L-V2.0is indicated there. This code indicates that there is a version 2.0 board on the chip inside 8227L.
In some cases, the sticker may be missing or worn out. Then you will have to remove the top metal cover (by unscrewing 4-6 screws around the perimeter). On the greenest printed circuit board (motherboard) there is always a silk-screen printing - a white inscription directly on the PCB.
What to do if the sticker is not readable?
If the sticker is damaged or missing, take a photo of the printed circuit board itself in good resolution. Upload the photo to specialized forums (for example, w3bsit3-dns.com in the "Android radios" section). Experts can often determine the model by the location of connectors and chips.
Using ADB and computer diagnostics
For advanced users who need comprehensive information, there is a connection method via USB debugging. This requires a laptop and the ADB (Android Debug Bridge) package installed. This method allows you to access the system log and configuration files.
First you need to activate developer mode. Go to Settings → About device and quickly click 7-10 times on the field Build number. A notification will appear indicating that you have become a developer. Then in the menu that appears For developers turn on the item USB debugging.
Connect the radio to the computer via a USB cable (usually the port marked as USB 1 or BT/USB). On a PC, open a command line in the folder with ADB and enter the command:
adb shell getprop | grep modelThis command will display a system property containing the real name of the model, which is written in the file build.prop. It is also useful to run the command adb shell cat /proc/cpuinfoto see detailed information about the processor, which cannot be faked in software.
⚠️ Attention: Drivers for car radios often differ from standard Android drivers. If the computer does not see the device, try installing universal drivers Google USB Driver or specific drivers for chips Rockchip / MediaTek.
If ADB does not connect, the USB port on the radio may be configured only for charging. Try changing the USB settings in the developer menu, switching the mode from “Charge only” to “MTP” or “PTP”.
The ADB command is the only way to get 100% guaranteed information about the hardware if the manufacturer has hidden it in the menu and on stickers.
Identifying the model by external features and connectors
Sometimes there is neither access to the menu nor the ability to disassemble the device. In such cases, the model can be determined by indirect signs: the location of the buttons, the type of connectors and the configuration. Experienced installers know that certain series of radios have unique design features.
Pay attention to the connector on the back. The presence of a specific 16-pin connector Canbus of a certain shape may indicate a series. The type of antenna connector is also important: in European models it is usually DIN (round), and in Asian models - Jack 3.5 or Fakra.
- 📺 Screen: The presence of a physical screen on/off button (separate from the Reset button) is often typical for platforms K2 i K7.
- 📺 Logo: The logo can be changed upon loading, but if it is standard (Android robot), this indicates stock or close to stock firmware.
- 📺 Remote control: The shape and layout of the buttons on the remote control are often unique for a specific manufacturing plant.
Take a photo of the back panel with all connectors and the front panel. Use image search in Google or Yandex. Algorithms do a good job of finding similar devices on AliExpress or eBay, where product names often contain real platform codes.
Frequently asked questions (FAQ)
Why do the settings indicate one version of Android, but applications say another?
This is a common practice among Chinese manufacturers. The file build.prop prescribes a fake version (for example, Android 10) to make the radio look more modern, while the real kernel may be based on Android 6 or 8. Diagnostic applications read the real kernel, and the settings menu reads the substituted value.
Is it possible to flash a radio from another model if the processor the same?
Strongly not recommended. Even with the same processor (for example, PX6), the boards (PCB), port layout, screens and touchscreen controllers may differ. Firmware from another model will most likely lead to a non-functional touch screen, no sound, or a complete system failure.
Where can I find the firmware if I recognize the model?
The best source is the profile thread on the 4PDA forum in the “Android radios” section. It contains firmware databases, divided by platform (MTCD, K2, PX5, etc.). The files can also be found on the official website of the board manufacturer (if known), for example, on XY Auto or Topway.
What is an MCU and why update it separately?
MCU (Micro Controller Unit) is a microcontroller responsible for the operation of buttons, power management, CAN bus and radio tuner. It runs independently of the main Android processor. An MCU update is required if the buttons on the steering wheel stop working, the time is not saved, or the radio is faulty. MCU and system firmware (Android) always come in separate files.
How to find the model if the screen is black and the radio does not turn on?
In this case, only a physical examination will help. It is necessary to remove the device, remove the cover and photograph the markings on the printed circuit board. You can also try connecting the power directly to the contacts on the connector (observing 12V polarity) to see if the indication lights up, but this requires the skills of an electrician.
