Very good

I use this every day and really like it. It does traffic almost as well as google. I wish it had a few more refinements, but with ios 9.03 it is stable and working very well. I especially love the hud unit. I can plan my route in my office so when I get to my car I am already to go. With traffic data updated to my phone, I know exactly when I need to walk out the door.
