Hi All, I will be traveling to Puerto Rico in a couple of weeks for vacation. Luckily at&t does not charge for roaming down there! I will be renting a car to get around, and would like to avoid paying the $10 per day fee for a navigation system and use my phone as my GPS device. A friend of mine was on a business trip and he was telling me that you just get a map with directions but turn to turn did not work (he did not say which app he was using) Can anyone confirm that turn by turn GPS works in Puerto Rico? Is it app specific? I already purchased MotionX GPS Drive, but if it is app specific I would be OK with purchasing another app as they are mostly inexpensive. Many thanks for your help, and Happy Holidays!
