Actually, the navigation app was a separate app in itself, just like the Places app...it was not an entry point into the navigation. Yes they are all linked together, but why remove an app that is the most benificial Google maps takes you through many more steps to start navigation, and it is very inaccurate. I have never had a problem with using navigation (meaning I always get to where I need to go). Navigation through Google Maps is much more tedious, and does not give me reliable real-time directions, as the Navigation app did. I KNOW IT HAS ALWAYS BEEN A BETA APP, but there was never a problem until this update. I could go to navigation, type or speak a location, address, or intersection, and get there. Now, Google Maps provides the weirdest directions, and sometimes cannot determine where you are, constantly rerouting you to streets that are no where near you.
I'll try to uninstall this update like a previous user stated, and see if it works.
