title: Display Google Map Direction instructions in different languages
body: <p>I am using Google Map service. Now I integrated Google Map Direction into my application, but all direction instructions are English.</p>
  
  <p>Anyone know the way to translate it into other languages? (e.g Vietnamese). You can see the site: maps.google.com, when you use your own language, all the direction instructions are translated into your language. That's what I need.</p>
  
  <p>Thanks :)</p>
