Our F250 came with the OEM navigation system, most of the time we use both when towing. The Rand McNally "Don" and Ford nav system "Hillary" both have their good features, but whenever there is a conflict, we defer to Don

and mute Hillary!

Maybe one day Ford or GM or Ram will wake up and equip their "built for towing" vehicles nav systems with the ability to enter parameters for trailers.
