Owners of TEYES CC3 multimedia systems often wonder about the integration of modern navigation services into the standard interface of the head unit. The popularity of Android Auto is growing, and the desire to see the usual Google or Yandex map on the radio screen is quite natural. The setup process may seem complicated only at first glance, but with the right approach it takes no more than 15 minutes.
The main difficulty lies in the fact that the stock TEYES firmware does not always contain built-in support for native Android Auto, especially in earlier versions of the software. However, the architecture of the device based Android 10 allows you to implement this function programmatically. You do not need to solder the board or buy additional modules, you just need to properly prepare the system.
Before you begin, it is important to understand which activation method is suitable for your configuration. There are several ways: using the built-in Zlink application, installing a third-party APK file via USB, or using AA Mirror mode. It is critically important to accurately determine your firmware version in the Settings menu, as this will determine the installation method you choose.
Checking compatibility and preparing the system
The first step is to thoroughly diagnostics of the current state of the head unit. Don't rush to download files until you're sure your hardware is ready for the changes. Open the settings menu and go to the “About” or “Car Info” section. Here you are interested in the firmware version number, which usually looks like a series of numbers and letters.
Make sure that the device has free space in the internal memory. To install additional modules and map caching, you will need at least 500 MB of free space. If the memory is full, delete unused applications or clear the cache using the built-in tools.
Also check the version of Bluetooth and Wi-Fi modules. For stable operation of the wireless protocol, up-to-date drivers are required, which are often updated along with the system software. If your version is older than a year, it makes sense to consider updating.
Before installing any APK files, make a backup copy of important data, if such an option is provided by your firmware version.
Installation method through the built-in Zlink application
The easiest and safest way is to activate the function through a pre-installed application Zlink. This is a standard solution that is optimized for working with TEYES processors and does not require root access. In most cases, it is already installed on the system by default.
Find the Zlink icon on the home screen or in the application menu. When you first start it, the system will ask for permission to access your microphone, contacts and phone. Agree to all requests, otherwise voice control will not work. Next, select the mode Android Auto in the app interface.
⚠️ Attention: If you see an error message or a black screen when starting Zlink, your firmware version may require updating the application itself via a USB drive.
To connect your smartphone, pair via Bluetooth. Turn on Bluetooth on your phone, find a device with a name similar to "Car Kit" or "Zlink" and pair it. After successful connection, the Android Auto interface should appear automatically.
☑️ Checking Zlink
Install Android Auto via USB and APK files
If the standard application is missing or does not work correctly, you can use the manual installation method of the APK file. This method requires the use of a USB drive and a file manager. You will need an installer file that is compatible with the processor architecture of your device (usually ARM).
Copy the downloaded file AndroidAuto.apk to the root of the USB flash drive. Insert the drive into the USB port of the head unit. Open a file manager (for example, "File Manager" or "ES Explorer") and find the installation file.
When starting the installation, the system may warn you about the risks of installing from unknown sources. You need to go to your security settings and allow applications to be installed from this source. After confirmation, the installation process will begin.
Settings → Applications → Special access → Install unknown applications → Allow for File ManagerAfter installation is complete, a new icon will appear in the menu. Launch it and follow the instructions on the phone screen to finally set up your Google account. This method gives you more control over the version of the software you are using.
What to do if the installation is blocked?
If the system says “The application is not installed,” try downloading an APK file of a different version or architecture. Sometimes clearing the package installer cache before trying again helps.
Setting up wireless and wired connections
Modern versions of Android Auto support both wired and wireless connections. A wired connection via a USB cable provides more stable data transfer and simultaneous charging of the smartphone. The wireless method is convenient because it does not require extra wires, but can consume more battery power on the phone.
For a wired connection, use a high-quality cable that supports data transfer. Cheap "charge only" cables will not work. Connect your phone to the port marked "Phone" or that has a special marking.
| Connection type | Operating speed | Stability | Phone charging |
|---|---|---|---|
| USB Cable | High | Maximum | Yes |
| Wi-Fi Direct | Medium | Depends on interference | No (flow) |
| Bluetooth + Wi-Fi | Low (audio only) | Medium | No |
When setting up wireless mode, make sure both Wi-Fi and Bluetooth are turned on on your phone. The head unit will create an access point to connect to. The first launch always requires confirmation on the smartphone screen.
For the first connection, always use a USB cable, even if you plan to use wireless mode in the future. This is necessary for the initial exchange of security keys.
Solving common problems and errors
During the setup process, users may encounter various technical difficulties. One of the common problems is a disconnected connection or no sound in the navigator. This is often solved by checking the audio channel settings in the CAR CFG menu.
If Android Auto starts but does not show the map, check the date and time settings. A time mismatch between the head unit and Google servers may block services. Set up automatic time synchronization via the network.
⚠️ Attention: The settings menu interface may differ depending on the TEYES firmware version. If you don't find the item you're looking for, check the official documentation for your specific model.
Also worth mentioning is the problem with the microphone. If the other person cannot hear you, check whether the microphone on the device itself or on the phone is blocked. In some cases, you need to switch the audio source in the call settings from “Handsfree” to “Internal Mic.”
If you constantly freeze, try resetting the Android Auto application on your phone. Go to your phone settings, find the Android Auto application, select “Memory” and click “Clear cache” and “Reset settings”.
Optimization and additional settings
After successful installation, it is recommended to fine-tune for maximum comfort. In the Android Auto menu, you can change the theme, the order of application tiles, and the behavior of the screen for incoming calls.
To improve performance, disable unnecessary widgets on the home screen of the head unit. This will free up RAM and speed up the interface response. It's also useful to set Android Auto to start automatically when you connect your phone.
Use Developer Mode with caution. Enabling USB debugging may be required for advanced users, but the average driver does not need these features and may reduce system stability.
Hidden features of AA Mirror
The AA Mirror application allows you to cast the entire phone screen, not just compatible applications. This is useful for navigators that do not have official support for Android Auto.
Frequently asked questions (FAQ)
