In the queue is to be able to create a simple Google Maps version of your trip to display on your device or even the cars browser. No ETA for this as of yet.It would be nice if EVTO could save maps for a specific trip to the iDevice on request so even if there are no live updates to the predictions at least there is a reference to the plan.
But this sounds like you would like to see just an image file so it could be seen with no connectivity at all? I could look at a static Google Map as a possibility.
