If you're wondering why the USB port in your Toyota Yaris isn't working, there are a couple of common reasons. A frequent cause for the USB port to fail is a blown fuse, which can happen and render the port non-functional. Fortunately, replacing a fuse is a quick and simple task that takes less than a minute. Another possible reason for the malfunction could be damaged or corroded wiring over time. To address this issue, it's best to have a professional handle the replacement of the wiring for you.
Problems with the USB port in the Toyota Yaris may be due to a faulty USB fuse.
It varies based on what you're connecting. The USB port won't detect USB flash drives larger than 32GB since they aren't in FAT32 format. Compatibility with MirrorLink can be problematic on this particular model, mainly working with older phones like the Samsung S3 or earlier models. However, there are third-party remedies you can find online.
