does author read this thread? any chance for navit advance? tried used latest release on my N810 - works but not stable, crashes

and I thing implementing maps autoloading - is not a big deal... in XML better have absolute folder name, then store maps in subfolders of this folder - then read all subfolders and show with complete path in menu

you just store maps as, for example (+ means directory)

Borocco Kingdom+ (country)
--- Main City.img (capital city)
--- Territory+ (other country part)
------ Sister's Village.img (some village)
------ Roadmap.img (other country roads)

and we have choice for each map in Navit

Borocco Kingdom/Main City
...
Borocco Kingdom/Territory/Roadmap
