Hy guys, i have a TT XL with 2GB of space and 8.010 patched navcore. I would like to update my map to 890 but here are the questions:

i want an Italy map and a Europe West one. For Italy no problem but for the second one...what the difference between Europe_West / Europe_1GB_West / Western_Europe / Western_Europe_1GB ??? Ok, maybe the difference is about the MB but what else?

What about this clone maps? Am i supposed to consider a clone map or what?
