Thank you very much for your efforts, though I'm not sure I understand much from your discussion,

Just in case, I've just checked the backup folders with all the files from the original BMW navigation before and after the update to 3490 firmware stored on my PC for any oem.* files and found just oem_wallpaper.bmp in the .System folder which is actually a BMW headlights customised lock screen and it's the same picture of the the Wallpaper.jpg file in the Pictures folder.
In addition I also couldn't find logo.bin file.

Looking forward to your further investigation.
Please let me know if you need any files from those backup folders.
most of the config files will removed after boot. The logo.bin file you can get it from the thread "[Only registered and activated users can see links. ]" or use [Only registered and activated users can see links. ]to make the 34xx logo.
