Does "Download Route" work for other parts of the world? I am in China getting ready to take the new transcontentental train from Shanghai to Lhasa, Tibet, and then I will continue overland to Nepal. Since downloading maps on the fly will be difficult due to lack of cellular phone service in many spots during the trip, I want to download all of the maps along the train route in advance. What is the best approach for this need? Should I do it by defining the corners and doing a mass download? I am concerned this approach will take way too much memory and it will down load maps that really are not part of the route. Suggestions??

Great app!!!
