How do I use navigate function on my watch?

[fluenty]

I think one of the advantages using Android Wear is to have the navigation function on my watch without having to put my phone out of my pocket. But when I tried "navigate to [somewhere]", it never worked. It just showed me the search results which are not really related.

Anyone knows how it works?

"ok google"
"Navigate to nearest mcdonalds"

From memory I had to unlock my phone and look at the maps app the first time I did this, works fine now. There was a period recently where it wouldn't show the navigation on the phone but this appears to be fixed with the latest update of maps.
