To address static or dropped calls on Apple CarPlay, ensure a stable connection and troubleshoot potential issues with your phone, car's infotainment system, and the USB cable.
I found the latest troubleshooting steps:
Update iOS and car's infotainment system software: Outdated software can cause compatibility issues.
Reset network settings: Go to Settings > General > Reset > Reset Network Settings to resolve potential network issues.
Check for interference: Wireless interference from nearby devices or power lines can affect CarPlay connections.
Check audio settings: Ensure the audio is set to play through the car's speakers.
Ensure Siri is enabled: Siri is required for some CarPlay features.
Check call audio routing: Go to Settings > Accessibility > Touch > Call Audio Routing to make sure it's set to automatic
I hope that helps!
