What are the reasons why the car USB cannot read the USB flash drive?
2 Answers
Here is an introduction to the reasons and solutions for the car USB not being able to read the USB flash drive: USB flash drive not recognized: The car USB may not recognize USB flash drives with excessively large capacities. You can try using a smaller capacity USB flash drive for testing. Unsupported format: If the USB flash drive format is not supported by the car's USB interface, format the USB flash drive to FAT format. Conversion method: Insert the USB flash drive into a computer; locate the USB flash drive on the computer; right-click on the USB flash drive and select Format; under File System, choose FAT; select Quick Format; once completed, the USB flash drive will be in FAT format, and the car USB interface should recognize it.
I encountered the same issue last month - my car's USB port wouldn't recognize the flash drive, which was really annoying. At first I thought the flash drive was broken, but a new one didn't work either. Later I discovered the old drive had the wrong format - the car system only accepts FAT32, while my drive was NTFS. I recommend trying a small capacity flash drive (under 16GB) formatted as FAT32. Also, check the USB port for dust or looseness - cleaning it with alcohol swabs helped in my case. If that doesn't work, it might be a system bug - try restarting the vehicle or visiting the dealership for a software update, which usually solves it. Don't rush to hardware repairs - start with simple troubleshooting. Remember to pull over safely when checking these issues while driving.
