Whenever I talk on the phone, my screen is obscured with an alert that says mobile data is not available. So the phone is useless for using Google Maps when driving and talking on the phone. Will Verizon's Navigator work when I'm driving and talking on the phone? I'm guessing Verizon will never be able to get Advanced Calling working for the Moto X, but would gladly pay if Navigator works while I'm talking on the phone
