  If your Bosch Tuner isn't detecting a USB or SD storage device, it might not comply with USB mass storage standards. Try using a device that does. Avoid USB hubs, or connect the storage device directly to the USB port. Ensure you're using FAT, FAT32, or exFAT file structure. If an electrical current stronger than allowable was applied to the unit’s USB socket, wait several minutes. The rating (allowable current) for this unit is 500 mA or less per USB port. Reformat the USB or SD card with a PC that has been known to give good results.

  If your Bosch Tuner isn't detecting your USB or SD storage device, it could be due to several reasons. First, ensure the device complies with USB mass storage standards. Some USB hubs may not operate correctly, so try a different hub or connect the storage device directly. Use only FAT, FAT32, and exFAT file structures. Wait several minutes if the connection was terminated due to excessive electrical current. Reformat the USB or SD card with a PC to ensure proper partitioning.
