I'm going on a trip to the east coast. I have an iPad 2 and an iPhone 3GS. Can anyone recommend a good gps app I can keep maps locally on the iPad and iPhone to save data charges or if I go out of range. I'm not looking for a free option and willing to spend the money needed.
I would also like turn by turn.
I looked at the Navigon but some commenters said it doesn't tell you to turn until it is to late at times.
