I want to try the software, but it doesn't seem to load any kind of map: the software loads, but there is just nothing showing on the map area. The coordinates in status bar are all zeros.

I've downloaded montrealisland.img from http://mapcenter2.cgpsmapper.com/mapview.php?id=1862 which I found from http://gpsmapsearch.com/ and copied to /media/mmc1 (the internal 2GB)

What I modified in the /usr/share/navit.xml file:

- <navit center="4531.42 N 737339.38 W" zoom="32"
- Disabled the sample map mapset
- Enabled the Garmin mapset and pointed to "/media/mmc1/montrealisland.img"

The config file is /usr/share/navit/navit.xml, right? I edited it with VI under the ROOT shell to get write access.
