Modern multimedia systems Cars require regular maintenance, and Incar head units are no exception. Software updates aren't just a way to get new features, but also a necessary measure to fix bugs and improve stability. Android and improved compatibility with navigation apps. Many owners are experiencing issues with the built-in update center, which either doesn't work or returns connection errors.
In this article, we will discuss in detail how to properly update your car radio. Incar via WiFi, what are the nuances when working with Chinese OEM firmware, and how to avoid bricking your device. The process requires careful attention, as interrupting data recording can lead to irreversible consequences for electronic control unit.
Before starting the process, you need to make sure your device actually supports over-the-air (OTA) or network updates, as some budget models have limited functionality. We'll cover both options: the standard one through system settings and the advanced one through the engineering menu or dedicated apps.
⚠️ Caution: The firmware update process always carries risks. Make sure the car is parked in a location with a strong WiFi signal and the engine is off or the generator is running to avoid voltage surges in the on-board network.
Preparing for the software update procedure
The first step is to identify the current software version and the exact model of your head unit. Incar There are many modifications of similar Android car stereos, using different processors (Rockchip, Allwinner, MediaTek) and different Android versions. Attempting to install firmware from a different model may result in complete inoperability. touchscreen or sound path.
You will need a stable internet connection. It is best to use your smartphone in hotspot mode with the highest signal strength, as built-in antennas in car stereos often have low sensitivity. It is also recommended to free up some storage space. internal memory device by deleting unnecessary applications or cache.
Check the car battery's charge. Although the update takes a short time, voltage surges during engine start-up can interrupt the process. If possible, connect an external charger to the battery terminals to maintain a stable voltage in the on-board system.
⚠️ Note: Menu interfaces may vary depending on the Android version and specific processor model. If you don't find the menu item specified in the instructions, look for a similar one in the "About System" or "About Device" sections.
Checking the version and searching for updates
First, you need to open the system settings. Find the icon on your desktop. Settings (Settings), it often looks like a gear. In the menu that opens, look for the section About the device (About Device) or SystemThis is where information about the current build is contained. Android and firmware versions.
Inside the "About" section, find the item System update (System Update). When you click it, the device will attempt to contact the manufacturer's server. In most cases, the default Incar server may not respond or display a "No updates" message, even if a new version exists. This is because dealers often ship devices with an older software version that doesn't have access to the latest repositories.
- 📱 Go to
Settings → About deviceand write down the current build number. - 🌐 Check for the "Check for updates" button in the system menu.
- 💾 Make sure your device has at least 1-2 GB of free space.
If the automatic search yields no results, you'll need to search for the firmware manually. To do this, you'll need to know the exact processor model and screen resolution. Processor information is often hidden. To view it, you'll need to click on the item several times. Build number (Build Number) in the "About" menu until the message "You are now a developer" appears. After this, a hidden section may appear in the menu. Factory settings (Factory Settings), where in the section Information The CPU type will be indicated.
Methods for connecting to WiFi and the network
Connection quality directly impacts download speed and the integrity of downloaded packages. Built-in WiFi modules in Incar car stereos often operate only in the 2.4 GHz band and do not support modern WPA3 encryption standards. For a successful update, it is recommended to use a network with WPA2-PSK encryption.
If you're using your smartphone as a hotspot, make sure it has data enabled and compatibility mode set. In your Android smartphone's hotspot settings, find the "AP Range" option and select 2.4 GHzIt's also helpful to disable traffic saving to prevent the system from interrupting the download of large firmware files.
In some cases, the stereo may not detect a 5 GHz network or networks with a hidden SSID. If you have a dual-band router, try temporarily separating the networks by giving them different names and connecting the stereo to the 2.4 GHz network. This will improve connection stability during the critical phase. data loading.
Recommended access point parameters:
SSID: Incar_Update
Security: WPA2-Personal
Band: 2.4 GHz
Channel: 1, 6, or 11 (least busy)
Manual firmware installation via WiFi
If the built-in update menu doesn't work, you can use the manual installation method using WiFi to transfer the file to your device. To do this, you'll need to download the correct firmware file (usually an archive). .zip or a set of files .img) to a computer or smartphone, and then transfer it to the radio.
There are two main ways to transfer a file: via cloud storage or via a local network. The first option is simpler: install a file management app (for example, ES File Explorer or X-Plore). Upload the firmware to the cloud (Google Drive, Dropbox) from your phone, then open the cloud on the radio and download the file to the internal memory.
☑️ Pre-installation checklist
After downloading the file to your device, locate it using a file manager. If it's a system update APK file, the system will prompt you to install it. If it's a full system image, you may need to run a special installer, which is often bundled with the firmware or already built into the system. Local Update.
⚠️ Warning: Never attempt to interrupt the installation process after the Android logo or progress bar appears. This may damage the bootloader, and the only way to restore the radio is by re-soldering the memory chip or connecting the UART console.
Using the engineering menu to update
Advanced users can update via the engineering menu (Factory Settings). This method is often necessary when the standard interface blocks the installation of an older or modified version of the software. Access to this menu is usually password-protected.
Log in Factory settings (Factory Settings). In the password field, try standard combinations such as 8888, 1234, 0000 or 1617If none of the above works, you can find the password by searching for it by processor model on specialized forums. Inside the menu, find the tab Update or Flash.
Here you can select the path to the firmware file you previously copied to the internal storage. The system will prompt you to confirm the action. Once confirmed, the partition reflashing process will begin. bootloader, system And recovery.
| Parameter | Description | Recommended value |
|---|---|---|
| Source | Where to get the firmware file | Local / Internal Storage |
| Update type | Complete data clearing or saving | Wipe Data (Recommended) |
| Signature verification | Requiring a digital signature on a file | Disabled (for custom firmware) |
| Reboot mode | Action after installation | Auto Reboot |
What should I do if my radio is stuck in a reboot cycle?
If your device constantly reboots after an update, try pressing and holding the Reset button (usually the small hole on the front panel) while turning on the power. If this doesn't help, you'll need to connect it to a PC via a male-to-male USB cable and use SP Flash Tool or a similar program to restore the bootloader.
Possible errors and solutions
During the update process, users often encounter the error "Parsing package error" or "Installation failed." This means the firmware file was corrupted during download or is not compatible with the current version. AndroidIn this case, you need to redownload the file, preferably from a different source, and verify its checksum (MD5), if provided by the developer.
Another common issue is no sound or non-functional WiFi after updating. This indicates that the firmware is designed for a different hardware platform (for example, the WiFi module drivers are incompatible). The only solution is to find the firmware specifically for your board model (MCU version).
If the update was successful but the system is running slowly, perform a factory reset (Factory Reset) through the recovery menu. This will remove any remaining old configuration files that may conflict with the new software version.
- 🔄 "System partition is full" error: Clear the app cache before installing.
- 📉 Slow download speed: Disconnect other devices from the WiFi hotspot.
- ❌ Unsupported format: Make sure the file extension is .zip or .apk, not .rar or .7z.
Frequently Asked Questions (FAQ)
Is it possible to update an Incar radio if there is no WiFi access?
Yes, this is possible. You can download the firmware file to your computer, then transfer it to a USB flash drive (formatted in FAT32). Insert the flash drive into the car stereo's USB port, locate the file using a file manager, and start the installation. However, this method is less reliable, as it depends on the quality of the USB port and file system.
Will the update reset my settings and apps?
In most cases, over-the-air (OTA) updates preserve your data. However, manually installing via the engineering menu with the "Wipe Data" option or upgrading your Android version (for example, from 9 to 10) will erase all data. Always back up important contacts and navigation settings.
Where can I find the correct firmware for my Incar model?
The official Incar website often doesn't provide direct links to the files. It's best to search for firmware on specialized forums (such as 4PDA), specifying the exact processor model and MCU version, which can be found in the "About the system" section. You can also contact the device seller.
Why did the sound disappear after the update?
Most likely, the firmware was installed with incorrect audio codec drivers or incorrectly configured CAN bus parameters. Try resetting to factory settings (Factory Settings) change the car type or head unit model to a similar one, after which the system will rewrite the audio configuration.
