What is the experience of mobile phone card?

Didi called a car and the driver's mobile phone began to navigate. I sit in the back and play with my mobile phone. Suddenly I heard the navigation saying that there was a plane ahead. I feel great after listening to it. Aircraft can still be detected in mobile navigation. Then after about three seconds, the navigation said, bullet train, I glanced at the driver and asked him, master, what kind of high-tech navigation are you? I saw him press the home button of his mobile phone, and after a moment of meditation, he said that his mobile phone was a little stuck. After that, the navigation rang again, the driveway.
