What are the reasons for no response when connecting a USB flash drive to the car's USB port?

[LaGianna]

The reasons for no response when connecting a USB flash drive to the car's USB port are as follows: 1. File format: Most vehicles can only recognize music files in MP3 and WMA formats. If the music files downloaded to the USB flash drive are in an incompatible format, the vehicle may fail to read them. 2. Storage path: If the music files in the USB flash drive are stored in a path that is too deep, the vehicle may also fail to read them. The solution is to place the music files in the root directory of the USB flash drive. 3. USB flash drive issue: Some vehicles, especially older models, may not support large-capacity USB flash drives. Therefore, it is advisable not to purchase a USB flash drive with excessive capacity. 4. USB port issue: Currently, most vehicle models are equipped with USB ports designed for powering electronic devices or charging mobile phones, which may not be capable of reading data from a USB flash drive.
