Double check image size and file size...if one is off even by "1" it will not import.
Try using an empty, of all but the images, usb.

Oh...how many wallpapers are stored in the crv?
Have you removed the current wallpapers? I think you can only store three...at least on my '12 I can only store three.

2012 owners manual says for following:
Photo must be in the usb "root directory"...not in a folder.
Only 2mb
1680x936 pixels
Up to 64 characters in the file name...I use only names, no numbers or symbols.

Try reformatting the usb drive...who knows??? nothing to lose by trying.
Reformat to fat32
No folders...just plain storage.
Double check image size, format and pixel size...maybe start fresh with the originals?
LOL still trying...good luck
