title: google maps turn-by-turn navigation
body: <p>I writing a web app(html5 and angular) where I use google maps to create a route. If the user uses the web app via mobile phone I would like to open a native google map app to show the route turn-by-turn navigation. Is this possible? </p>
  
  <p>Thank you</p>
  
  <p>Edit: I can invoke a native with the following link right? 
  <a href="http://maps.google.com/maps?saddr=New+York&amp;daddr=San+Francisco" rel="nofollow">http://maps.google.com/maps?saddr=New+York&amp;daddr=San+Francisco</a></p>
  
  <p>Is it possible for me add waypoints in between?</p>
