This app will get you killed. You're in the middle of driving somewhere you don't know where the place is so you're depending on the app all of a sudden the app goes dead. Now you have to unplug replug try to get it to come back on if it comes back on it may give you 3 minutes more worth of information especially that you passed the point where you were supposed to turn now you have to make a series of turns and u turns to get back to where it dropped dead. Garmin works everytime.
