my phone is not showing the image of maps when it’s connected to my car. You can only hear the voice speaking

Hello Amia2,

We'd like to confirm what's going on so we can provide you the right steps. Are you using CarPlay in your vehicle or another service? Also, do other functions work such as music? What do you see on the display when this is happening?

If you are using CarPlay, then we'd recommend these steps for troubleshooting: If you need help with CarPlay - Apple Support

1. First, make sure that your country or region supports CarPlay and that your car supports CarPlay. If you're unsure if your car supports CarPlay, contact the vehicle manufacturer.

2. Make sure that your iPhone has the latest version of iOS. If your iPhone is updated to the latest version of iOS, follow these steps — checking CarPlay after each step:

3. Check your connection to your CarPlay stereo:

If you have a wired connection, try connecting again with a different USB cable to a different USB port if you have one.

If you have a wireless connection, make sure that Wi-Fi and Bluetooth are enabled under Settings > Wi-Fi and Settings > Bluetooth.

4. If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display.

5. Restart your iPhone and your car. 

6. Make sure that Siri is on.

7. If your iPhone isn't detected by CarPlay, make sure that CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions, tap Allowed Apps and make sure that CarPlay is enabled.

8. Go to Settings > General > CarPlay, tap your car, then tap Forget This Car. Then set up CarPlay again.

9. Make sure that your CarPlay stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.

Thanks!
