Nokia has stuck a promo video online for its new Ovi Maps service that will now offer turn-by-turn voice guidance and other navigational features for its GPS-enabled smartphones.

You can hit play on the video above to have two fresh-faced Nokia staffers explain the new service to you in a mini road movie.

The new Ovi Maps is available now for download for 10 Nokia Symbian handsets, with more smartphones due to be added in the coming weeks, while from March 2010 it will be preloaded on all GPS-enabled Nokia smartphones.

Although the N97 won't be included in the initial run of handsets available, Nokia has confirmed that it will be available by the end of the month.

The current list of compatible Nokia devices is as follows: Nokia N97 mini, Nokia 5800 XpressMusic, Nokia 5800 Navigation Edition, Nokia E52, Nokia E55, Nokia E72, Nokia 5230, Nokia 6710 Navigator, Nokia 6730 classic and Nokia X6.
