I already posted this, check the Ovi Blog comments where a Nokia employee named @Niini says that the Ovi Maps team is working on turn-by-turn for N900: http://blog.ovi.com/2010/03/02/new-p...bile/#comments

I also posted the response from Nokia USA Customer Care which said that N900, not Meego/Harmattan, will have free turn-by-turn navigation as well.

Sure it may take some time, but with these answers I am confident that N900 will have Ovi Maps with turn-by-turn navigation. (just hope the 2 person who answered were not from an outsourced help desk and don't have a clue what they're saying... but that doesn't seem the case)

Anyway, it is hard to understand why the Maemo team don't confirm this since other employees did... Maybe some strategy reason or even due to bureaucracy common on large companies, who knows...
