      If you're using Android Auto with your Toyota Car Navigation system and can't hear hands-free call audio, try disconnecting your phone from the USB cable to see if hands-free calls work via the standard hands-free system. If that works, reconnect via Android Auto and increase the system volume to check if the audio is now audible. Also, verify if other sounds are playing through the vehicle’s speakers.

      If your Apple CarPlay/Android Auto screen shows artifacts or the audio has noise on your Toyota Car Navigation system, the USB cable might be damaged. To check, connect your device to another system like a PC to see if it recognizes the device and starts charging. If the cable is damaged, replace it.

      Kelly FernandezAug 17, 2025
      If your Toyota Car Navigation system doesn't resume the original audio after interrupt audio (like navigation) plays from a non-compatible Apple CarPlay application, you should manually switch the audio source. Alternatively, avoid using applications that aren't compatible with Apple CarPlay. Consider updating to the latest iOS and application versions, as some navigation applications are compatible from iOS 12 onwards.
