How to Fix Android Auto Communication Error 16

In this guide, I will discuss solutions for fixing the Android Auto Communication Error 16.

Reasons Behind Connection Failures

First, ensure that you are using a high-quality USB cable, preferably the one that came with your device. A faulty or low-quality cable can cause communication errors.

Next, make sure that both your Android device and your car’s head unit have the latest software updates installed. Outdated software can lead to compatibility issues and communication errors.

Check if any of the apps you are trying to use with Android Auto, such as Google Maps, Spotify, or Audible, are not up to date. Updating these apps can help resolve any communication errors.

If you are still experiencing connection failures, try restarting both your Android device and your car’s head unit. Sometimes a simple restart can fix communication errors.

If all else fails, try resetting the connection settings in the Android Auto app on your phone. This can sometimes resolve stubborn communication errors.

Essential Troubleshooting Steps

  • Ensure that the USB cable is properly connected to both the Android device and the car’s infotainment system.
  • Try using a different USB cable to rule out any issues with the current one.
  • Make sure the USB port on both devices is clean and free of debris.

2. Restart Devices

  • Turn off both the Android device and the car’s infotainment system.
  • Wait a few minutes before turning them back on.
  • Reconnect the USB cable and check if the communication error persists.

3. Update Android Auto App

  • Open the Google Play Store on the Android device.
  • Search for the Android Auto app and check for any available updates.
  • Download and install the latest version of the app.

4. Clear App Data

  • Go to the Settings on the Android device.
  • Find the Apps or Applications section.
  • Locate the Android Auto app and select it.
  • Tap on Clear Data or Clear Cache to remove any corrupt files causing the communication error.

Advanced Solutions for Persistent Issues

One advanced solution for fixing Android Auto Communication Error 16 is to update your Google Play Services on your device. This can help resolve any compatibility issues that may be causing the error message to appear.

Another option is to ensure that your USB-C cable is functioning properly and is compatible with your device. Using a faulty or incompatible cable can lead to communication errors between your Android device and your car’s system.

If updating Google Play Services and checking your USB-C cable does not work, try clearing the cache and data for the Android Auto app on your device. Sometimes, corrupted data can cause communication errors, and clearing the cache can help resolve this issue.

If the issue persists, try resetting your Android Auto preferences by going to the app settings and selecting “Reset app preferences.” This can reset any settings that may be causing the error to occur.

Lastly, if none of these solutions work, consider reaching out to the Android Auto support team for further assistance and feedback on how to resolve the communication error. They may have additional troubleshooting steps that can help pinpoint the exact cause of the issue and provide a solution.
