You can't beat Google's traffic updates. Maps are the most up-to-date (as opposed to Garmin and the like). Google Navigation needs some work but there is no other map app that has this type depth and visibility. Thanks to Google for making GPS worth it on a phone. Wish there was a way to directly save maps to the phone for offline viewing- maybe in an update? Route navigation based on current traffic conditions would also be a plus. Sometimes Navigation doesn?t re-route correctly but just a minor, minor issue and in only in very few routes. Bottom line is this app is incredible.
