Unable to use GPS on my iPhone 16 Pro Max

Hello, when I was using my iPhone 16 pro mix for gps, it stopped talking during my trip recently. It only talks when I started at the beginning! After a while, the app was still working but without voice. I tried to restart the phone. I still have 138 GB storage available on my phone. What should I do now? Please help me to solve this issue! It’s very important! Thank you so much for your support and help!🙏🙏🙏
