In order to compete with the navigation apps that both Apple and Google give away for free, Garmin is introducing a new Android and iOS nav app called Víago that sells for just $2 (on sale for $1 until July 13th), with advanced functionality available as in-app purchases. It's still not free, but compared to Garmin's previous app which sold for $50, it might just be worth upgrading your smartphone's default maps app.
