They’re in there, but a bit of a pain in the ass to find...
So press the top center icon on the display and select Navigation. Then press the “Where To?” Pop up. Then scroll down and select myTrips. Then select FordPass Trips, and finally select your saved trip from the list.
First time through I was just like you. I spent all this time putting a trip together on the app and couldn’t find it in the truck the first several tries.
Good luck!
