One of the App Store’s go-to GPS apps, TomTom, has received an update to its Canada and U.S. iteration that adds some new features and updates a few road maps.

Among the changes are an improves search function, maps that have been updated to include more up-to-date maps to account for road changes, premium voices, a Stop Navigation button that will pause guidance and put the app into sleep mode (and pick up where it left off), and a new background feature (which you can choose to opt out of) that sends info to TomTom about how you use the app in order to improve user experience. It’s also important to note that this update affects device compatibility and it will no longer work on the iPhone 3G, iPod Touch 2nd Gen, and any device using iOS 4.X or earlier.

If you use TomTom on your iOS device, and meet the criteria for compatibility, it’s definitely worth checking out!
