Even as the rise of free navigation apps gives most paid competitors pause (if not killing them outright), Navigon has managed to stay well ahead of the pack with a robust, oft-updated smartphone solution, despite charging over $80 for the privilege. But now, even that last bit can change. For $30, Navigon's MyRegion gives you its premium MobileNavigator software at around one-third the price, with the simple caveat that you only get maps for one-third of the US (East, West or Central) to go with it. Should you drive out of your designated zone, Navigon will generously allow you to buy another chunk a la carte for $15; and all of Navigon's other add-ons, including the new MyRoutes feature (customized route recommendations and alternate routes) are similarly available. It's not quite as delectable as gratis, but we have to admit a certain admiration for Navigon turning software investment into impulse buy. Oh, and speaking of impulsive: Navigon's offering MyRegion for the low, low price of $25 through April 12th.
