We're new to the Apple world with the purchase of our Pad 3 G 64 gig. We wanted a navigation system to use on our I pad when we traveled. We purchased an HD Co-Pilot and initially used it with some success in the Santa Barbara area. However, when we tried to use it on a trip to Park City, Utah, it was totally unacceptable. It repeatedly hung after trying to load the app. We could not input a destination or select anything on the menu. This problem persisted in Salt Lake City as well as Saint George and Las Vegas during our drive to Park City. Google Maps and Google Earth worked perfectly in all these places. Right now, we wouldn't recommend this program to anyone and are extremely sorry we paid $30.00. Our kids were right - "Don't ever pay for an app!"
