If you are like me and couldn't get it via software update on your phone, then try connecting your phone to Nokia Suite and search, that's how I got mine.
About the Nokia Suite 2.0
Nokia Maps Suite 2.0 puts all the information you need (Maps, Drive, Public Transit and Weather) in one smart package with shortcuts and homescreen access specifically for Symbian. Put your photos on the map, instantly access public transport info, see weather in multiple cities and plan your route
This suite combines Nokia Maps and Nokia Drive as well as the new Nokia Public Transport, and enhances them with key application shortcuts developed specifically for Symbian. Now you can instantly access useful information such as weather, guides, and your current location. Existing capabilities, such as deep traffic integration and full offline maps, are combined with new, rich enhancements such as tighter application integration, improved ease of use, and greater personalization options.What’s new in this release?
I think the Voice search feature is only available in the UK, with plans to release it in other locations in the near future.
You already know Nokia Maps for delivering best-in-class mapping, navigation, and photorealistic 3D views. This latest release raises the bar even further with a new way to show and tell where you’ve been with photos on a map, new voice search capability, and direct home-screen access to your favorite places. Finding your way has never been easier.
Though the Maps Suite has been available via BetaLabs for a while now, this is it's formal release.
