We just came to Myrtle Beach SC from Michigan using Apple maps turn by turn navigation. Turn by turn navigation is the cats ass. it worked great,even better than an older GPS that we had. I was really surprised that it worked well in the mountains of West Virginia. For what I have used it for I would not give Apple maps a bad mark. We have iPhones on Verizon and on most of the 900+mile trip we had LTE. Only once in WV we lost signal completely. I am really impressed with the iPhone, Verizon and the navigation.
