GabrieleStockunaite Im pretty sure that it’s a software bug of some kind. I got a reply from support and it’s pretty much the same steps that I’ve tried already.
We’re really sorry to hear that you’re having an issue with failing to connect to Android Auto. We’re here to help in any way we can. We kindly request that you follow the troubleshooting steps provided below to address the issue.
Update Software:
Ensure your Nothing Phone 3a Pro is running the latest version of Nothing OS and Android Auto. Go to Settings > System > System Updates to check for updates.
Enable USB Debugging:
Activate USB debugging in Developer Options:
Navigate to Settings > About Phone > Tap “Build Number” seven times.
Return to Settings > System > Developer Options and enable USB debugging.
Use a High-Quality USB Cable:
Confirm that your USB cable supports data transfer, not just charging. If possible, test with multiple cables.
Check Car Compatibility:
Verify that your car’s infotainment system supports Android Auto. Consult the vehicle’s manual or manufacturer for compatibility details.
Reset Connections:
Restore your car’s multimedia system to factory settings and reconnect your phone using a wired connection.
Switch USB Ports:
If your car has multiple USB ports, try connecting through a different port.
Android Auto Permissions:
Ensure Android Auto permissions are granted when prompted on your phone during setup.
Please try these and let us know how it goes or if you have any questions, please don’t hesitate to reach out.
Warm regards,
