im trying to plan a journey home from a destination but it keeps wiping the fields out, is it because i’m not at my destination yet .ie do i have to be at destination place to then plan journey home again as i need to be in time for a ferry from 200 miles away from destination to get back home again. so need to plan a leaving time icluding stops for fuel along the way which I can do from my current place leaving out. many thanks in advance
