I recently updated the firmware in the SDS100. When it powers on and the computer recognizes the scanner and I hit I. It says "writing to SD card" then shuts off. I reset the settings and tried it again and it shuts off again. I don't think it is the SD card. once I reset it, I then re-entered my location and began scanning and picking up signals fine. I even recorded some stuff to write to the SD card to see if there was any issues and it worked fine. any suggestions would be nice!
