Common BMW X3 USB music problems and how USB4Car fixes them.

The dash port charges the phone but plays nothing USB4Car fixes this automatically

The fix: That's the charge-only port. The media port is in the center armrest — plug the stick there and it indexes immediately.

A 128 GB stick isn't seen on an F25 USB4Car fixes this automatically

The fix: F25s read FAT32 only, and big sticks ship as exFAT. Reformat as FAT32 (32 GB sticks are the no-surprises choice).

Album covers missing on the widescreen USB4Car fixes this automatically

The fix: iDrive shows embedded art only. Embed covers into the files at ~500×500 — folder.jpg files are ignored.
