download map - how long does it take???

hello sirs.
I've just installed navigami on samsung d980 (full touchscreen), and it seems to work fine with a royaltek external gps. I succeefully set up the connection between mobile and PC via bluetooth (in the navigami the connection is seen as serial port. right? if I set bluetooth the message is something like "connectivity not available", I guess because it is busy with PC).
Then I tried to download the map, but nothing happens... how long does it take to download a map? what should I see in the screen during download? I cannot see anything but coordinates of last know position and blank screen.
Regards

new installation...!!!

mostly it takes almost an hour to download the map and I also had to face the same problem while I was working with 1z0-042, 1z0-147 and 640-816 and re installation did the trick...
