Useless without data roaming

I spent a week in Ireland and this app was all but useless. I could use it to view maps in a browsing sense, but it DOES NOT WORK as a GPS without connecting to a data netwok. The iphone uses a-GPS (assisted GPS), meaning that (at least in Ireland) it cannot tell where it is without the data netwok. I was sold on this app based on the fact that I did not want to pay for data roaming. Instead, I got to Ireland and found out that I would have to pay the car rental company an additional €60 for a GPS device because this software was useless as a turn-by-turn unit. What a letdown.
