The public transportation information comes via Garmin's new Urban Guidance in-app purchase. Urban Guidance accounts for trains, trams, busses and water taxis when finding pedestrian routes, and auto-tags the location of your car when starting a foot route. StreetPilot Onboard for the iPhone also gained Google Street View and Panorama View 3D as in-app purchases.
Urban Guidance is available as a $2.99 in-app purchase.
