Hello Michaelj1220,
Welcome to Apple Support Communities!
We want to help so you can hear the navigation during your drive.
We'll need to learn more to isolate the issue. Are you using CarPlay for the navigation, or a third-party app or service?
If using CarPlay, make sure turn-by-turn directions are not muted using these steps:
"Follow turn-by-turn directions
As CarPlay follows your progress, it speaks turn-by-turn directions to your destination.
Do any of the following at any time during your trip:
- Add a stop to your driving directions: Select the ETA display at the bottom left, select Add Stop, then choose a destination or use Siri to search for one.
- End directions at any time: Say something to Siri like “Stop navigating,” or select the estimated time of arrival (ETA) display at the bottom left, then choose End Route.
- Mute turn-by-turn directions: Tap
, then choose
to mute all directions."
Try restarting your iPhone if the issue remains. We hope this helps to correct the issue or change your mute setting so you hear all the directions again.
Cheers!
