Hello, I just completed the most recent map update, and now my SD card is no longer recognized by my device. I tried reformatting it with the device, but the SD card is not recognized. I then tried reformatting it with my computer, and I get an error message saying it is not possible to reformat it. Lastly, I tried reformatting it with my camera, and it appeared to work, however when I put the SD card back into my GPS, it still does not recognize it (and nor does my computer). Is it possible for a map update to break/corrupt my SD card?
