    Default DNN990HD Internal SD Card Software repair?

    Hi, could anyone help me with restoring the internal SD card software for this unit? I updated it to software version 1.8, while at the same time I tried to image the internal sd card to a new one (16gb) because I also have a DNX690HD and the internal sd cards in the units apparently get hot and get corrupted. I was able to rescue that one, however, I can't seem to rescue the DNN990HD. Also, after the update, the original internal sd card no longer works correctly either. Everything appears to work, except for the garmin software/GPS, which when you try and start the gps on it, it looks like this:
