I went to use my navigation (the blue arrow) yesterday and it is no longer in my apps! WTF?? Where did it go and can I get it back? I do not think I had a recent update. Problem solved... Google recently rolled everything into MAPS. If you want the quick key to navigation you need to uninstall the recent updates. Everything will be back to normal. You can still get to the Blue navigation tool with the updates by opening Maps and then go to drop down...from there you will see the navigation arrow. From what I learned the update is going to roll everything into google maps.
