Hi all.* We took a decent trip today, and put the Nav in my '19 to the test.* On the way home, the Nav would throw up an "alternate" route (try to re-route some strange way), then the estimated arrival time would adjust accordingly.* Like add 2 or 3 hours to the trip.* It would go back to the original route, but the estimated time would take a while to reset.* Sometimes reducing the time by a few minutes in a couple of seconds.* We have another trip coming up soon (Houston to central Florida), and I'm a bit worried about the false re-routing.* I won't be able to get it the the dealer before then.* Is there a reset or something I could try if it does it again?* I hope this makes sense, it's a little hard to describe.
