[TG] [TG11] Upgrade to Lighthouse 3

[Tom - Raymarine - Moderator]

Hello Hube,

Usually, this sort of thing is down to one of the following:

1. Upgrade card is formatted with ExFAT file-system. Many modern large-capacity cards come formatted as ExFAT, but this is proprietary/licenced by Microsoft and our displays don't support it. Re-formatting as FAT/FAT32 should solve this problem. You can do that either on a Windows PC or a Mac.
2. A corrupted/incomplete download. When you download a file, your computer will often allocate space for it and then fill that space, but if the download doesn't quite complete then you can get a file which looks like the right size but is incomplete. It then fails the display's file-integrity check and the upgrade can't start.
3. Removing the SD card from the computer before the copy process has finished. Unfortunately the time when the copy progress bar disappears from your computer screen is not actually the time when the file has been fully written to the card, only when the file has been fully loaded into the write-buffer. Pulling the card out to early means that you have an incomplete/corrupt file, as above. Make sure you right-click and do Eject and wait until the computer says it's ok before unplugging the card.
   

If in doubt, reformat your (blank) card (don't format a chart card!) as FAT/FAT32, re-download the file, copy to the card, do Eject and only remove when told it's ok, and try again. I think it will work then.

Regards,
Tom
