Welcome to itT, dwould!

I like navit, too. Version 0.1.0 was released 26 nov 2008. it's supposed to have a more finger-friendly GUI.
http://sourceforge.net/forum/forum.php?forum_id=891703

and here's some advice for compiling:

(don't follow the "download the binaries" link there; it's old. i just put this link here for someone who has scratchbox and knows how to compile things because someone called "gerritv" gives some advice for it there.)

as far as I know, it's just waiting to be compiled for maemo.
