I intentionally choose NO TOLLS when I travel. It is less expensive and usually a more scenic route. I have been having trouble that the We have a shorter way pops up and I don't want to choose Okay because I already have the route I want so I ignore thinking that must default to keep as I'm going.

Seems it does it anyway because all of a sudden I'm on toll roads. I think you should have a yes or no option.

I also found out then when you choose a route (perhaps no toll as an example; not necessarily the shortest route) when you stop your car for gas or rest stop it defaults back to shortest route.
