This app crashes and malfunctions a LOT. eg, You lose phone coverage for a brief moment, and then it just stays offline with no warning while you drive in the wrong direction. OR when voice controls suddenly stop working, but it won't switch to typing with the car stopped and in park (as it should), unless you turn off the car, restart your phone, re-plug the phone in. Then, maybe. All in all more frustrating then helpful. A basic Bluetooth connection with no app is a million times better.
