Just download the latest maps you need from the iGo maps section, you can use TomTom or Here ( Navteq ) what you prefer. You can only use the countries you need, don't suppose you need to install the whole world .
Read the instructions there where to put them and copy the maps, 3D, Poi, licenses etc to the right place.
It's all in the download.
Latest TomTom = 2017 09. Here ( Navteq ) 2017 Q4.
Done.
Good luck.
