found a bit of an inconvenience. cant really say its a bug, but it was a bit of a PITA. download a route, and mark it to "Auto-Update" do not provide a means for your tablet to Auto-Update, like do not allow the connection to a GPRS phone or WiFi. drive off course and allow the Auto-Update to start. it gives you a "Host not found" error message with an "OK" button, since the tablet cannot get to the internet. the error message repeats so quickly that you almost cant do anything but click "OK". i am not sure what should happen in this case, but the app is useless in this scenario, since the error message will cancel the menuing. trying to clear the route took me about 8 tries with very quick tapping in between error messages. if an additional button could be put into that error box allowing you to turn off Auto-Update, you could avoid the error message looping.
