This is a 3D map showing my route, marked in green. Road directions are in the right hand window. Your live map may show the availablility of webcams in the route ahead, marked with little icons. Select the icon, and live pictures are transmitted to the car through the cellular phone. Looks like clear sailing in my lane ahead.
