And I will be the third.
Navigon beats Google maps, Apple maps, TomTom and Garmin.
Outside of the convenience of having it on my phone, the prices just seem to much. In the US, $40 for the app and then all the features one would want or expect are $5 to $15 add-ons...each!
If travelling in out of the way places was a key part of my job I would probably change my tune, but Apple Maps has actually been perfect in the large US cities I have visited. And now with Google Maps as a back-up for poi's, I'm covered...at no cost...
Oh..and I have used Waze as well, but traffic is simply not a huge issue where I live and travel most. And I really don't care for the UI, accuracy (constantly moved me over to adjacent side streets while driving down the highway at 70 mph) and it is very distracting. If Apple could simply integrate the live traffic notifications on the screen (as an option) and updated poi's, Apple Maps would be close to perfect for me....best UI, accuracy, speed for me so far in the US.
