Recently out camping overnight in Moab I got an error when I tried to leave in my 2021 Winnebago Revel AKA 2020 Mercedes Benz Sprinter Van. The error came up in the dash when I pushed the start button. It said " Place key in marked area". This area is not marked in any way I could tell. But it's located under the cup holders just above the floor in the. center dash area. I think the key became un-synced for one reason or the other. Regardless, inserting it in that spot allowed me to start the vehicle and drive. I have not got the error again since then.
