We should be completely seamless, allowing off-line and online to function without the user seeing any difference. This would allow 100% perfect navigation any time anywhere without having to worry about missing a turn being sent on a hiatus and keep you always going in the right direction.. this feature is absolutely necessary on long trips and places where there’s no cell reception so that you always have the route running and never have to worry about a pause because off-line mode has been initiated and you just continue on your way without seeing any difference in your screen this seems like the ultimate GPS without having GPS failure which happens too. And you could always have your hands on the wheel not be trying to figure out anything on the screen and just drive this makes total sense I don’t see that it is available and it’s just an algorithm, so just do it.
