On Xiaomi phones, if you open the navigation application at the same time and want to listen to music, you can follow the steps below:

1. Open the navigation application: find your frequently used Navigation app, such as Amap, Baidu Maps or Google Maps, and open the app.

2. Set navigation route: In the navigation application, enter your destination and confirm the navigation route.

3. Switch to the background: In the navigation application, you can see an option to minimize or switch to the background. Typically, this is a miniaturized icon that you click to switch the navigation app to the background.

4. Open the music application: Go back to your home screen or application list, find your favorite music application, such as NetEase Cloud Music, QQ Music or Spotify, etc., and open it.

5. Select a music list or song: In the music application, you can select a playlist, album or single, etc., and then select the music you want to listen to.

6. Start playing music: After selecting the song you want to play, click the play button or corresponding control option to start playing music. Now you can enjoy navigation and music functions at the same time. Please note that the specific steps may vary depending on different Xiaomi phone models and Android versions, but they are generally similar.
