I understand that this is as good as it gets so far in terms of turn-by-turn GPS. I also understand that 1.0 did not originally have turn-by-turn, which allowed it to make its way into the app store...until they updated it and now it has it along with GPS location services. And lastly, I am aware there is no voice. My questions are to the people who have bought this app: 1. Does the GPS dot/arrow follow you as you drive and how well does it work? 2. Lack of voice aside, does the turn-by-turn work well and how? 3. I read on the app details that it works without a cellular connection or wifi connection. Does the GPS still work? 4. Are the maps up-to-date and what is your opinion about the maps 5. What is your overall opinion of this application (out of a five star rating, improvements, positives, negatives, worth the money, etc)? I ask, because I am considering buying it.
