I had the same issue. But this is how I was able to complete. Instead of using any SD card, the company said, use Verbatim or Kingston or Lexar. I used Verbatim 8gb and it worked perfectly. Before downloading, I formatted the SD and unzipped the files onto the SD card from my computer. Before, the updates failed many times because I used SanDisk SD card, but with this card, updates were "complete." Now, new update, the radio works better than before. Thanks
