The iTunes App Store offers NAVIGON MobileNavigator: USA for Apple iPhone, iPod touch, and iPad (pictured) for $29.99. That's tied with our mention from a year ago and the lowest price we've ever seen for the Apple version of this GPS app. (We saw a similar NAVIGON GPS app, which also included maps of Canada, for the same price over a year ago.) This GPS navigation software for iPhone features Lane Assistant Pro, Text-to-Speech, optional in-app purchases of NAVIGON Traffic Live in the US, and more.

Of note, NAVIGON U.S. East, NAVIGON U.S. West, or NAVIGON U.S. Central, the regional versions, are available for $19.99 each. That's tied with our mention from nearly two years ago.
