This may be the same problem that others are having with saving bookmarks. I had been using Navit on a ubuntu laptop with no problems and recently have moved to a android tablet with Navit 0.5.0 4785. I usually look up my destinations on google, get the lat/long and make a new bookmark entry. I continue to do that now but in order for them to show up in Navit, I have to save the bookmark.txt, reopen it and make a change. Not a change but something like erasing the last quotation mark, retyping the quotation mark and saving again. Only after making a "change" will the bookmark show up in Navit.
