navigami

I've been trying to install the navigami navigator on my LG Renoir and i'm having two problems:

1- I need the brazilian map to go for the routes and i'm not able to download the maps. My cell connects to the internet by WI-FI conection. This way i do'n't need to connect to the pc via bluetooth, right? How do i download a map or brazil?

2- How do i make the searches to go from one point to another in the navigami navigator?

Tks for the help
