Hey guys, I just wanted your opinion on the best navigation app. We all know that Maps is terrible compared to what Google Navigation. I know that there is Garmin, TomTom, CoPilot, and a few others. I just wanted to see if people have any preference towards one. For my usage, I would just like great turn-by-turn voice and be able to calculate the destination quickly along with re-routes. I would not be using this for traffic so that isn't a concern. What do you guys use and how do you like it?
