Navigon, although not as well known in the United States, offers an excellent UI and navigation solution with maps stored locally on storage card, clear visual guidance, and voice-guided turn-by-turn navigation for many smartphone platforms. It is one of the best and most popular smartphone solutions for iPhone owners and now the company is running a promotion from the regular retail price for Windows Mobile users. If you’re an HTC HD2 or other Windows Mobile device in need of some guidance, you can order the Navigon solution between May 14 and June 11 for $49.99, down from the regular $89.99.
On the 14th, be sure to check out the Navigon page for more details on the promotion.
Unlike Bing–which recently added navigation features for free–Navigon doesn’t require a constant Internet connection and you can navigate anywhere that your device has access to the sky for positioning satellites.
