Must congratulate you guys for a much improved navigation UI. The menu button bottom right makes the UI much less cluttered. The direction info top left is very big and clear. I like the way that after a turn the distance and symbol for next turn is displayed straight away. Often navigation apps just show a straight ahead arrow which I have always thought a little pointless.
I still think that the speed limit and speed icons are too small. Could these two be moved from the lower bar to top right on the map, placed one above the other and made bigger. This would work in both portrait and landscape modes and give more room at the bottom to display distance and time information. This information could be on one line instead of two. I think this would make the navigation screen very clear and easier to read.
Hope this makes sense.
