@richtea999 good question!

So the first is really just you making sure that you've downloaded the relevant regions. Having the routes downloaded for offline use is a good idea in the event you really have no internet at all - just so you can reload the route.

Offline mode prevents the navigation module from making any internet connection. This results in no traffic information and track navigation won't work anymore but besides that, everything works as expected.

Situation 2 is impossible. The app will approximate your location when reception is bad (eg. tunnels) but this won't as long as you indicate. If you drive 20 minutes without any reception (GPS), your location will just seem stuck. I'd say a minute or so (maximum) without GPS might work. Do note there will be a difference between straight tunnels (where the app can predict loss of reception) and no reception at all.
