Neil, tks for your reply. But admitting that i'm leaving files the way they are (CNNA as gmapprom and Brazil as gmapsupp in sd card) can I just replace my gmapprom file? Another question I've already replaced it but I'm finding odd that I can't find any preloaded POI's, is that normal? They only appear when I'm in the US or they should also appear here in Brazil? My fw is 5.00.
