I can totally imagine that. Recently I've been helping a guy with tweaking his integrated car navigation/radio/media player and I spent some time browsing through its firmware and file system. I saw the translation strings and man, they were horrible. Also half of the stuff wasn't even translated (though it didn't show anywhere on the UI).

BTW. half of the files and directories were named in Chinese which made my work very "fun", but that's another story...
