I tried this at the weekend - downloaded the file and unzipped on a Mac. Then I only copied the logos I needed onto an SD card (otherwise you'll end up with several hundred logos to scroll through). Once I'd mounted the SD card, I discovered that the first part of the list consisted of the logo file names, but no content. Scrolling further down the list gave me the file name plus a thumbnail of the logo. This is what I selected, and it seemed to work - both for DAB and FM.
