You also are missing the Help and JPEG folders. The second doesn't matter a fig really but on-board help is handy sometimes. The attached file has all languages in Help, but i guess you may only want English & some EU files, so you can just remove what you don't want to save some space. [Only registered and activated users can see links. ]. Same with voice, text and kb files but you'll need appropriate text and TTS voices if you're using the Oxford Language Guide.

Not that you really absolutely need them, but here are the rest of the files for your Garmin folder too [although i see your .System folder isn't showing, so maybe you've chosen to hide some stuff in Windows folder options]. [Only registered and activated users can see links. ].

PS: Please just ignore our resident Russian Bear, he's missing his winter hibernation. Generally doesn't seem to like Europeans much but is usually ok with ppl from DownUnder. If you tell him you're more Kiwi than Tulip Sniffer then he'll be fine ..... maybe

Just to add to his learned words of wisdom, another way the get the keyboard files from the .rgn is to open it with RGN_Tool and just select save to get the file pk_text.zip which can then be extracted to obtain the folder 'Keyboards' containing all the .kbd files.
