What are the reasons why the car does not respond when inserting a USB drive with songs?

Reasons why the car USB suddenly does not read the USB drive: 1. Loose USB drive: Since the USB drive is plugged into the car's USB interface for a long time during use, the vibration and shaking of the car body during driving can easily cause it to become loose. Once it becomes loose, the car USB may suddenly stop reading the USB drive. 2. Damaged USB drive: The possibility of a damaged USB drive is relatively small, but due to the less-than-ideal environment inside the car (especially under high temperatures in summer), the possibility of damage cannot be ruled out. 3. Damaged USB interface: The possibility of a damaged USB interface is believed to be even smaller than that of a damaged USB drive, but when the above assumptions are not the issue, the possibility of a damaged USB interface cannot be ruled out.
Last time I also encountered the awkward situation where my USB drive had no sound when playing music! After plugging it in, the USB icon didn’t even show up on the screen. Upon checking, I found the USB drive was recognized by the car system as a storage device—unplugging and reinserting it fixed the issue. For older car stereos, be mindful of format limitations, as they only recognize USB drives formatted in FAT32. If the music suddenly stops midway, it’s likely due to poor contact with the USB drive—loose ports on low-quality drives are quite common. Once, when I tried my wife’s metal-shell USB drive, it didn’t work at all, but switching back to a regular plastic-shell one worked immediately. Unstable power supply from the car’s USB port can also cause intermittent reading, especially when the dashcam is occupying the cigarette lighter. The simplest trick is to borrow a friend’s USB drive to test and rule out whether the USB drive itself is faulty.
