The phenomenon that songs are stuck on the U disk of a car is probably caused by the different format of the U disk and the version of the car. The solution is to change the USB flash drive into the same format as the car.
It is also possible that the Song bit rate of U disk is relatively high and the processor chip of lathe is relatively low-end. At this time, when the U disk is being read, the processing speed of the cpu of the single chip microcomputer will not keep up, so it is stuck; The solution is to download the songs with the bit rate of 128kbps, put them on a USB flash drive, and then connect them with the car to listen to the songs.
