How to find the Android radio model: from settings to hidden marks

Have you bought a used radio on Android, lost the box from the new one, or just want to update the firmware, but don’t know the exact model of the device? This problem is familiar to many owners of car multimedia systems. Without the exact model name, it is impossible to find the correct drivers, firmware or even accessories - from frames to remote controls.

In this article we will analyze all possible methods model definitions Android radiosincluding hidden menus, physical markings on the case and even firmware analysis. You will learn where to look for information in the settings, how to decipher factory stickers, and what to do if all the labels are erased. And also - how to avoid mistakes when searching for data that can lead to incompatibility with firmware or accessories.

1. Checking the model in the Android radio settings

The most obvious and safest way is to look into the device’s system settings. Most radios on Android (even Chinese brands like Pumpkin, Joying or Xtrons) display the model in the "About phone" or "About tablet" menu. Here's how to get there:

1. 📱 Click on gear icon (Settings) on the main screen or in the notification panel.
2. 🔍 Scroll down and select the section About the tablet, About the device or System information (the name depends on the version of Android and the shell).
3. 📋 Look for the lines Device model, Model number or Hardware Model. It may say something like PX5-Octa, MTCD-E or JY-UL075N.

If the "About tablet" section is missing, try an alternative path:

• 🔧 Settings → System → About device
• 🔧 Settings → Advanced → Software information
• 🔧 Settings → All settings → About tablet (for radios with shell CarLauncher)

⚠️ Attention: On some radios (especially with Android 4.4–6.0) The "About the tablet" section may be hidden by the manufacturer. In this case, try the method with engineering menu (section 3) or check the physical marking.

If the model is displayed in the format MTCE_KL720 or PX5-1024_64, this may not be the full name, but only the platform and configuration. Such data will be useful for searching for firmware, but to order spare parts it is better to check the full model (see section 5).

2. Using applications to determine the model

If the system settings do not provide complete information, they will come to the rescue. third-party utilities. They read data from the chipset, motherboard and firmware, often displaying more details than the standard Android menu. Here are the top 3 tested applications:

How to use:

1. 📲 Install one of the applications (for example, CPU-Z) via Google Play or using an APK file (if you do not have access to the Internet).
2. 🔍 Open the section Device or System.
3. 📋 Look for the lines Model, Hardware or Board. For example, in AIDA64 the necessary information may be in the section Android → System → Device Model.

If the application shows only the general platform (for example, Rockchip RK3368), this means that the radio manufacturer did not write a unique model name in the firmware. In this case, proceed to physical examination (section 5).

3. Engineering menu: hidden data about the model

Many Android radios have engineering menu (Engineer Mode), where technical data is hidden, including the model and version of the hardware platform. It can be accessed through secret codes or button combinations. Here's how to do it:

Method 1: Login codes

Try entering these combinations in the application Phone (yes, it’s even on radios!):

• 📞 ##4636## —general Android test menu
• 📞 #808##* —engineering menu for devices on Rockchip (for example, Joying)
• 📞 ##36446337## —for radios on Pumpkin and some Xtrons

Method 2: Button combinations

If the codes do not work, try the physical buttons:

• 🔘 Press Volume+ + Volume – + Power button for 5-10 seconds.
• 🔘 On some models Atoto i Eonon need to be pressed Menu + Power when turned on.

In the engineering menu, look for sections:

• 📋 Device Information → Model Name
• 📋 Hardware Info → Board Platform
• 📋 Version Info → Build Number (for example, rk3368_box_user_8.1)

⚠️ Attention: Do not change the parameters in the engineering menu if you are not sure of their purpose! Incorrect settings can lead to sensor failure, lack of sound, or even bricking of the device.

4. Firmware analysis and Build Number

If the model is not displayed either in settings or in applications, it can be calculated by firmware version (Build Number). This method is especially useful for Chinese radios without explicit marking. Here's how it works:

1. 📱 Find Build Number in settings (About the tablet → Build number). Example: rk3368_box_user_8.1.0_20210315.
2. 🔍 Break the line into parts:
   • rk3368 - platform (Rockchip 3368)
   • box - type device (radio)
   • 8.1.0 — Android version
   • 20210315 — firmware build date

Decryption example:

If yours Build Number — mt6580_720p_user_6.0, this means:

• 🔧 Platform: Mediatek MT6580 (budget chipset)
• 📺 Screen resolution: 720p (1280×720)
• 🤖 Android version: 6.0 Marshmallow

Such data allows you to narrow the search to 2-3 possible models, after which all that remains is to compare the appearance of the radio with the photo on manufacturers' websites.

5. Physical inspection: where to look for the model on the case

If the software methods do not work, there remains external inspection. Manufacturers often mark the model on:

• 🏷️ The sticker on the back panel (the most obvious place). Look for the lines Model, Type or P/N.
• 🔧 Under the removable frame (relevant for radios with detachable front panels, for example, Pioneer or Sony XAV).
• 🔌 Near the connectors (USB, antenna input or connector for rear view camera).
• 📦 On the box or in the documentation (if saved).

Examples markings:

• 📌 JY-UL075N — model from Joying with a 7-inch screen.
• 📌 PX5-Octa-MTCB-K —cassette player on the platform Pumpkin PX5 with an 8-core processor.
• 📌 ATOTO A6G2A7 —model from Atoto with Android Auto support.

If the sticker is erased or missing, inspect printed circuit board (when disassembling the radio), there may be:

• 🔧 Platform marking (RK3399, MT8163).
• 📋 Serial number (SN), by which you can find the model through manufacturer support.

⚠️ Attention: When disassembling the radio, turn off the power and battery of the car to avoid short circuits. If you are not confident in your skills, it is better to contact the service.

6. Search for a model by external features

If all the previous methods did not help, you can determine the model by characteristic features radio:

• 📏 Screen size (7", 9", 10.1", etc.).
• 🔧 Connectors:
  • 🔌 Mini USB - old models (until 2018).
  • 🔌 Type-C - modern radios (2020+).
  • 🔌 HDMI - premium devices (Atoto S8, Joying Tesla).
• 🎵 Logo on the front panel (even if the brand name is unknown, the logo can be found on Google using the image).
• 📱 Version Android (4.4, 8.1, 10, 11, etc.) - narrows the search.

Definition example:

If you have a radio with:

• 📺 10.1-inch screen,
• 🔌 connector Type-C i HDMI,
• 🤖 Android 10,
• 🎵 logo in the form of a stylized letter "A",

then with a high probability this is a model from the series Atoto A6 or Atoto S8.

To clarify:

1. 📸 Take a photo of the front and back panels radio.
2. 🔍 Upload a photo to Google Images or to the forums (4PDA, Drive2).
3. 💬 Describe all connectors, buttons and features in the topic - experienced users will help identify the model.

7. Contacting the manufacturer or seller

If an independent search is unsuccessful, you can remain formal request. Here's how to proceed:

• 📧 Write to the manufacturer (if the brand is known). Attach a photo of the radio, Build Number and serial number (if available). Support contacts are usually on the brand's website.
• 🛒 Contact the seller (if you bought it on AliExpress, Amazon or in a local store). They may have information about the batch.
• 🔧 Contact the service center. Craftsmen often come across “unnamed” radio tape recorders and can determine the model by the board or firmware.

Example of a letter to the manufacturer:

Hello!
I have a radio tape recorder made by you, but I can’t determine the exact model.
Device data:
- Build Number: [insert your number]
- Screen resolution: [for example, 1024x600]
- Connectors: [list]
- Photo: [attach]
Please tell me the name of the model and where I can download the firmware for it?
Thank you!

⚠️ Attention: Manufacturers of Chinese radios (for example, Pumpkin or Eonon) may take a long time to respond to requests. In this case, it is faster to get help on thematic forums.
