Yo. Just a simple question. Can you plug in your 3.5" external hard disk drive, formatted in FAT32 or NTFS and with 320 GB capacity, to one of those newer car stereos with the USB ports on the front? I would think it wouldn't work, and that those ports are only meant to handle usb thumb drives (flash memory). Because if they do work with any old computer hard drive, why don't more people do that? Thanks for any input.
