Trying to set up GPS for iPhone?

So I have the standard Google maps GPS on my phone but I'm wondering if there's a free update/application that allows the standard GPS to give me turn by turn voice directions so I don't have to risk my life trying to read the map on my phone as I drive to my destination.

Thanks in advance:)Trying to set up GPS for iPhone?
Yes, there are quite a few turn by turn GPS apps in the App Store.



For example, the top ones are TomTom, CoPilot, G-Map, iGo My Way, and Navigon Mobile Navigator.



I own all of these and I recommend TomTom.
