There are plenty of good turn by turn navigation apps though, at varying degrees of ability and price. If you want a good free turn by turn app I'd suggest the Mapquest app. Personally, I think that Navigon is well worth the money I paid for it, particularly since it keeps the maps stored locally, so you don't need a constant data connection to use it.
any idiot can read a map who needs turn by turn directions? Plus the iPhone map dosnt rotate with the phone so you can use it upside down for going south etc.
