Nokia Maps beta is by far the best Navigation tool (I tried every single one), until google starts to add real navigation to their google maps mobile application.
Things I like to change:
- search function should display similar results, if no results have been found.
- I don't like the way, the search results are categorized (walk / drive / Places). Often I have to browse through different categories to find the result I want.
I think the search function is very important. On the other parts, I'm very happy as it is.
Although the softkeys are fixed on the internal screen (and the menus are generally easier), the zoom in/out on the internal screen is controlled by left/right shift keys not the # * that appears by the icon.
Havent tried the turn by turn or traffic yet as I only subscribe when I need it.
