I have a 2019 Armada. When we set the GPS, the arrival time for our trip is always way off. For example, I just took a trip to Asheville. It's normally a 3.5 hr trip. When I first put the destination into the gps, it said the trip was going to take over 4.5 hrs. As we traveled, the eta would slowly come down. Is there a way to adjust this? Are others having the same problem?
