I hope it doesn't break up the discussion much to field a question from a total n00b but here goes.

First off thanks to the developers working on Navit, it looks like an awesome app.

I managed to get it installed automagically via the one-click-install link here;
http://tech.visser-scully.ca/?page_id=23
but since it only comes with a map of Munich of course I'll need to load my own.

I used the 'Planet extract' tool here; http://maps.navit-project.org/download/
.. which produced a "a binary file that can be used directly by Navit without further processing." this is where I have trouble. I copied that .bin file to my N800, I used xterm to locate Navit's .bin file and .xml of the Munich map -- but the dir is owned by root and I haven't found a way to get root access yet - so I can't write any files there.

Do I need to reinstall OS2008 with the R&D package (is it required to get root?) just to load new maps? Is there another way I'm not seeing?

any help would be greatly appreciated, thank you
