Hi Localapple,
It sounds like you're having an issue with the Apple Maps turn-by-turn navigation. If so, first ensure your iPhone is running the latest iOS version available. If needed you can find helpful steps for backing up and updating here: Update your iPhone or iPad - Apple Support
Next, check your precise location settings with the steps below. You can also find this information in the article here: View maps on iPhone
"Allow Maps to use your precise location
To find your location and provide accurate directions, iPhone must be connected to the internet, and Precise Location must be on.
- If Maps displays a message that Location Services is off: Tap the message, tap Turn On in Settings, then turn on Location Services.
- If Maps displays a message that Precise Location is off: Tap the message, tap Turn On in Settings, tap Location, then turn on Precise Location.
Cellular data rates may apply (see View or change cellular data settings on iPhone).
Note: To obtain useful location-related information in Maps, leave Significant Locations turned on in Settings > Privacy > Location Services > System Services."
You can also check additional settings with the help of the guide page here: Change settings for spoken directions in Maps on iPhone - Apple Support
Additionally, does the issue occur in any location or environment? If connected to Wi-Fi does the issue continue when testing? Keep us posted.
Cheers.
