I checked the radio button 'Origin' so that I can plan a route on a pre-loaded map without a GPS or internet connection. Also, what's the 'error parsing gpx file'? I tried opening downloaded Google street maps (with winmapper on my pc) and continually get this error. And, MM continually locks up. Can't figure why everyone raves about MM! I have never been more frustrated with an app. I have never been able to do any more than download a route with a GPS & internet connection.
