title: Intent to start a navigation activity
body: <p>In my application I have an option to start navigation to selected POI. Basically what I want is to launch a turn-by-turn navigator from my application. The thing is I don't know which (if any) navigator is installed.</p>
  
  <p>So, the question is how to start an intent by showing a list of suitable activities for navigation to the user first, letting him choose which one he would like to use? Also would be nice to find a way to pass extra parameters to selected activity (this sounds like an issue to me, since different navigation apps use different names for their extras, I guess).</p>
  
  <p>In case it's not clear: I'm looking for a way to DISPLAY A LIST OF SUITABLE APPLICATIONS FOR NAVIGATION WITH THE OPTION TO MAKE ONE DEFAULT.</p>
