Alright. I did actually use the install method you mentioned for Navit - and it works just fine this way except any maps actually showing up. Otherwise - for setting up I used this wiki articles:

1. http://wiki.navit-project.org/index....n770/n800/n810
2. http://wiki.navit-project.org/index.php/Garmin_maps

I did use two example configuration files provided in frist article. And I get the look I was supposed to with OSD - though as mentioned, no map view. I am aware that this setting will only detect maps set in /media/mmc1/map/ directory and this is where I placed my Gaarmin img file.

Now to the libgarmin configuration - this is where things got frustratingly difficult for me. Firstly, they are only available through SVN - which incidentally I know nothing about. But i figured it was not installed on my n810, as the command svn did not return anything but "command not found". Therefore I installed SVN support (point and click method). Alright - I thought I was getting somewhere - I try to use command svn co again to receive the files I needed.

First time I received something about UFT-8 error and while I tried to recreate the problem and actual error message, this time svn co worked and I think I have the files I need.

(just to explain - when it didn't work before, i tried downloading one by one and putting it into directory tree, it took too long on n810 so I tried in Windows and then transfer it over USB cable, but I gave up the plan when I saw that when downloaded these files had .htm extension. So I found this .deb package at http://www.tecdencia.net/navit/ (at the bottom) ... it claimed to have installed, but any tests were unsuccessful.)

Now, back on track - I have the directory structure I need to execute following commands:

cd libgarmin
./autosh.sh
make

And, as root :
make install


and then:

Be sure to update navit to latest cvs

reconfigure and build navit.

cd ../..
./autogen.sh && ./configure && make


Now this last part as I mentioned means nothing to me - update navit to latest cvs?! reconfigure and build? Really? Yeah, I ll do that ...

Well unfortunately I didn't get that far but it sure took my initiative away. I stopped at ./autosh.sh now. It just returns "-sh: ./autosh.sh: not found" though it is clearly there in the folder with other files. Using sudo, full path to the file doesn't work either and I can't actually determine what's wrong.

So here I am. And before this worked and I used libgarmin .deb package I also already set up navit.xml to point to appropriate garmin map.

I also found these instructions - http://libgarmin.sourceforge.net/ - but they seem to do the same thing by using more commands? Which should I follow?
