Doesnt work offline

App seems good for modes of Trans and choosing times. Disappointed that I cant use it offline EVEN THO IT SAYS "AVAILABLE OFFLINE". I dont want to pay for data plan to get the info. I want to look up the route in advance, save it (which is possible) then call it up offline. App says "no connection. Try again?"
