Google Maps

European users of Google Maps now have a new update that offers voice-guided lane navigation for highways located in Germany, France, Italy, Spain, the UK and Ireland.

Google states:

When you're in the turn-by-turn navigation mode, we can now make sure you don't miss your next turn or exit by showing you which lane to stay in or move to so you'll never find yourself darting across traffic at the last minute -- or worse, driving for miles down the wrong road. When you approach a junction or exit with multiple lanes, voice guidance will suggest which lanes are best for your route. You'll also have easy access to alternate routes while you're navigating, so you can choose the best drive for you.
