Purchased the app while on a trip to California, just worked perfectly for us, no problem in loading the California map. Back home I try to load the Canada map, it crashed, rebooted the iPad, try again and Crash again...... always half way thru the instalation. Maybe you should to break Canada in 3-4 pieces, you know it is a very large country and very few of us need to go from Vancouver to Montreal in one shot! ;-))
