I recently bought a 64gb flash drive for my f700 bt, unfortunately despite working on my computer great my hu wont read the usb at all. I then bought a 4gb run of the mill flash drive and it works great. I noticed my 64gb flashdrive is in the exfat format type where as the 4gb is in the fat32. are our units compatible with exfat? Also I bought a external harddrive laptop style that gets power from the usb. My unit also doesnt read that, and i think it may be a similar problem. Any advice would be great thanks

anyone? I have a 64gb harddrive (in "exfat") and a 250gb external (in ntfs) I would like to get them into fat32 how do i do it?

You need to format them in Windows, this isn't really an AVIC issue, google if you need.

I had no luck at all getting anything over 16GB to play nice.

Format in FAT32, there are plenty of formatting apps out there for free.
