The only workaround I’ve found for this annoyance is to put my phone into airplane mode after selecting my navigation route. GPS and navigation still works after doing this.
This way it doesn’t update the route with a ‘timesaving’ route or to an expensive toll route. It’s crazy I have to do this and far from ideal as I would like it to update if there really is a major timesaving route, eg if an accident occurs, but I don’t trust Google Maps now to not update now with a screen only navigation alert.
What it should do is alert me to this change with an audible alert and wait for me to actively approve this route change.
