At the begining, I would love to thank you to both of you for making time to respond on this, I do apprechiate. When I plug up navigation with PC, I can see SD for cameras as well as SD for maps. European map is added on SD for maps as unlocked map like this " EU NTU 2023.10 South IMG UnLocked (2.61 GB) ". Once I start device, it was showing message that maps are interuppted and they are not usable, as well as it shows that there is no instaled maps on device.

I have tried changing maps names multiple times, but it was not succesful.
