Yup - I installed it a while back. Haven't had to nav much since I got it so can't speak to its usefulness/usability, but the Favorites option was what attracted me...

 

I can already navigate to a contact so I guess I don't really see the advantage of installing this. I installed it a while back and removed due to I personally didn't see the point in having it. But did I miss something? What is so good about it? Can someone help me out, maybe I will give it another go.
