What to do if the USB does not work on my Hyundai AVANTE MTXM100AD?

If the USB on your Hyundai Car Navigation system isn't working, it might be due to several reasons. First, the USB memory could be damaged, so try formatting it to FAT 12/16/32. Another reason could be contamination of the USB memory. Remove any foreign substances from the USB contact surface. Also, avoid using a separately purchased USB HUB or extension cable; connect the USB directly to the multimedia terminal. Ensure you're using a standard USB Memory (Metal Cover Type USB Memory). HDD type, CF, and SD Memory are not supported. Finally, confirm that the USB contains supported music files (MP3, WMA).
