I'm visiting Ireland for a few days in August and plan to rent a car and drive around a lot. After looking at some of the "directions" on googlemaps I decided I will need GPS. I have an iPad 3G and thought it may be an ideal time to try out the GPS. However, I can only seem to find expensive 1 time fee GPS apps for ireland. Does anyone know of any reliable monthly fee options with downloaded maps? Or, does anyone know of a reliable carrier that offers micro sims and cheap(ish) data plans and then I could just use the included maps program? I'm not picky about whether it is an iPad or an iPhone program... obviously I'd like it to be designed for the iPad, but I can live with an iPhone program Thanks!!
