Well I was also saying that is if you don't have a signal you have to do that. If you do have a signal it has turn by turn navigation. At least the version I have does.
It is not like I sit there and stare at it all you have to do is give it a quick look and it will all make since.
I honestly use, when my wife doesn't have it, a dedicated navigation device. I feel like it does its job and it does it well. They are not even that expensive. You can actually get them for very cheap. Although I just used my iPad 2 and it worked like a champ!
Like I said at the end of what I wrote "to each their own" I just would never spend that much money on an app that you could get the job done for FREE.
