One other thing to watch out for: Avoid long folder and file names. The display on the nav unit can show roughly 24 characters before the folder/filename scrolls off the screen. If you have too many folders/files that scroll of the screen, it can make the listing of folders/files *extremely* slow and sometimes not even work at all. I went through and truncated all my folders on my flashdrive down to a length that would show on the nav screen, and it sped things up tremendously.
For example, rather than having a folder called:
Lady Gaga - The Fame Monster (Super Ultra Deluxe Whatever Edition)
Cut it down to something like:
Lady Gaga - Fame Monster
Do that for all the files and folders. It's a pain, but you'll be happier in the end.
