I rented a car last week for work for a drive to Chicago and brought along my USB stick to try it in another non-Chrysler vehicle. Quite miraculously, all folders and songs were recognized with the count matching iTunes precisely with 1,187 folders and 14,482 songs. I've tried NTFS and FAT32 as well as file copies from Windows directly as well as MediaMonkey. MediaMonkey produced better results but I can still see artists only A-S, and 1,2,3. T through Z are missing and the song count is short by approx. 4,000. Not sure what to try next.
