For those iPhone users, what is the best GPS app available? I'm used to the nav in both my TSX and Audi, and I'm looking for an app that will provide turn-by-turn directions. I'm going out of town for business in couple weeks, and I'd like to use my iPhone as a nav to show me around. So far, I'm leaning toward the app called "Where To? GPS points of interest", but I'm not sure if this app will offer what I'm looking for. Any help would be appreciated. Thanks.

 

Umm AFAIK maps is the only program that provides directions for the iPhone.

 

yeah nothing with turn by turn direction yet. Although there are rumors of a tomtom app
