where you get roadnav ipk?
can it work without GPS?
what map's format it use?
You can get roadnav from "New Packages Announcement" Thread on page 11.
It work also without gps and uses osm (openstreetmaps) format an Tiger for US.
I tried it and it works also with BT GPS, but it crashes on resize of the window and it have not the optimal size for the display (will contact the developer for eventuell resize of the buttons)
Is it possible to compile the alpha version (0.17) to exclude that this was an old bug of the program.
Greetings
Andreas
