Why can't the USB in a BMW be read?

[StJuniper]

BMW USB cannot be read because the navigation is not activated. You need to activate the navigation first to use the USB, or the USB format is incorrect, causing it to be unrecognizable. More related information about BMW is as follows: Brand Introduction: BMW (abbreviated as BMW) is a German automobile brand under the BMW Group.

Last time I drove my BMW out, I also encountered the issue of the USB not being recognized. After struggling for a while, I realized it was due to incompatible USB drive formats. BMW's infotainment system is quite picky—it generally doesn't recognize NTFS formats, so you need to use FAT32 or exFAT instead. Additionally, the quality of the USB drive matters a lot. Those cheap, no-name USB drives you can buy for a few bucks are the most likely to act up. If the USB doesn’t respond when plugged in, try starting the engine first—sometimes low battery voltage can cause the USB port to stop working. If you’ve tried two or three different USB drives and it still doesn’t work, chances are the USB port in the car is dusty or the fuse is blown, requiring you to disassemble the center console for cleaning and inspection. By the way, after a system update, newer BMW infotainment systems may also require the USB drive capacity to be no more than 128GB, something many people aren’t aware of.

It's common to see BMW owners complaining about USB port malfunctions, but many cases are actually caused by usage habits. For example, inserting or removing USB drives on bumpy roads can easily deform the contact springs inside the port. Additionally, prolonged exposure to sunlight can overheat and damage the USB drive's controller chip, so it's best not to leave USB drives in the car during summer. When purchasing USB drives, opt for industrial-grade products with metal casings, as plastic casings have a higher probability of deforming under heat. Aging car batteries can also affect performance - USB power becomes unstable when voltage drops below 12V. During regular maintenance, remember to have technicians check for USB module error codes using diagnostic computers. If a fuse blows, it's quite simple to replace it yourself - the fuse box can be found behind the glove compartment on the passenger side.
