Last Friday my Navigation worked fine, NOW it only shows a top down view when driving. The GPS works, it follows me on the streets with a blue arrow, but north is always up and there is no 3D view. There is no 'blue arrow' in the corner to click. If I go to menu, I can add layers or sat. view or back out. What gives? Anyone else? Is there a way I can remove the last update? Where is the Nav. ap in the settings? Google Nav and Nav arent listed.
