I had a similar problem with Gerrits deb, didn't notice it needed uncompressing. I have now build svn2001 and updated the file available from my server:
http://demigoth.org/files/navit_0.1.1-1_armel.deb
or you can get it from:
http://download.navit-project.org/navit/n800/svn/
I'm not sure if there is anything materially different between the two at the moment.
i've also updated the layouts on my blog:
http://danielwould.wordpress.com/navit-stuff/
to use the slightly newer hooks for the buttons. the bottom of the 3 now sets a background colour. but for the moment I can't get the alpha channel to do anything so it's just solid red rather than semi-transparent.
