On Thursday, Nokia announced it was making its Ovi Maps product free to use.
Previously a paid-for app, Ovi Maps is largely based on technology brought in-house by the acquisition of Navteq and other navigation companies such as Gate5.
Nokia's announcement came a few months after Google said it was introducing free turn-by-turn sat-nav functionality for US users of some Android phones. The new version of Ovi Maps offers similar functionality, but will work across the world and on a wider range of handsets.
Unlike Google Maps Navigation, the new Ovi Maps can also operate offline, so users can preload maps for foreign destinations, then travel overseas and use those maps without incurring data-roaming charges.
