TomTom International has updated its series of turn-by-turn navigation apps to take advantage of the new multitasking features in iOS 4. A required update for iOS 4 users, TomTom 1.4 adds support for the new background location feature available on multitasking-capable iOS 4 devices. The update provides continuous visual driving instructions on iPhone 4 and iPhone 3GS devices even while the user is on a call and background navigation for iPhone 4, iPhone 3GS and third-generation iPod touch devices allowing users to open other applications while still receiving spoken turn-by-turn directions. The update also adds several other new features including updated maps, sharing of routes via e-mail, the ability to add departure reminders directly to the iOS Calendar and a new fuel-efficient “Eco Route” selection. TomTom 1.4 for the U.S. & Canada is available from the App Store for $60 and is a free update for existing users. Versions for other regions can also be found via TomTom’s App Store page.
