iPhone Maps doesn't speak directions

Hello and welcome to Apple Support Communities, Stiegy.
If I understand your post correctly, the Maps app doesn't speak directions after you start out on a route. That would make it difficult to follow directions while driving. I'd like to help.
Try these steps:

Manage your Navigation Voice settings

When you use Maps on your iPhone or iPad that's connected to a Bluetooth accessory in your vehicle, you can access and manage your Navigation Voice settings. For example, you can turn your music down and hear Navigation Voice prompts through your stereo speakers and turn-by-turn directions on your iPhone or iPad. To manage these settings, follow these steps:

1. Open Maps on your iPhone or iPad and enter your destination.
2. After you tap to get directions, swipe up on the Route Card.
3. Tap Audio.
4. Tap the volume level that you want for Navigation Voice.

You can also control settings to pause the audio during navigation or control the audio output
from your iPhone or iPad. When audio plays, the audio output can only be managed from Control Center on your iPhone or iPad.

Let us know if that resolves this issue for you.
Thanks for using the Apple Support Communities. Take care.

Follewed the steps listed and still done have voice direction.

I aso wish an update would prevent the music from start when the phone connects to Bluetooth. It is annoying, please eliminate that feature. Let the phone users decide if they want to play music when conn to Bluetooth.

You need to make sure that your radio is set to be the output for the directions. When you plug the phone into your radio, if music starts, that is the fault of the radio not the iPhone. The radio is sending instructions to the phone to play the music. You have as much control over that as the radio set allows you.
