Thank you catymag

Another thing,
I have 2 maps on an internal flash drive ((gmapprom.img) City Navigator Middle East & Northern Africa NT 2015.10) and the other on the sd card ((gmapsupp.img) City Navigator Europe NTU (Unicode) 2015.20).
And I have 2 fils 3d ((gmapsupp.img) for City Navigator Middle East & Northern Africa NT 2015.10) And other ((gmapsupp.img) for City Navigator Europe NTU (Unicode) 2015.20)
Where do I put these files (3d) and by any name?.
