Thanks for clarifying. I have some further doubts now.
1. As I mentioned, I am not seeing any error in the device and I am also able to see the list of all maps in my maps option and able to check / uncheck them. When the img files were placed under /Garmin/Map/ folder then the device was not showing the maps name at all in my maps option. Could you clarify on what do you mean by ERROR in positioning as when i move the files as suggested by you, it does not show in the gps.
2. I have life time maps for North America which I would like to retain as well. I can see there is already a file named gmapprom.img under my .system folder. Would it impact my life time updates if I overwrite that file with the one from this thread ?
I would be surprised if you have enough space in the internal memory to cope with EU's files 8.5 GB & N.America.
I do not recommend using the internal memory for supplemental maps ,if any file corruption occurs you can brick your device which takes time & effort , with an SD card you can just remove it and start again. Using an SD card your Lifetime map device will still update normally without issues.
There are different hardware versions of this device that's why it's important to confirm the HWID
