Just curious. Does anyone have Navigation maps more current than "NA 1 15"? Thats what my 2017 came with.
As nearly as I can tell the map versions are just numbers and not dates -- unless all come deliberately two years out of date. All Sync 3 versions in all cars:
2016 car 1 14 map version
2017 car 1 15 map version -- in my 2017 Expedition
2018 car 1 16 map version
2019 car 1 17 map version
There is (was?) a USB kit that would update the maps. Keyed to VIN and/or SYNC3 unit so one-time-use. Don't have a part number or price. Anyone?
Upgrade requires about an hour with the engine idling.
This is common and inexcusable in a eleventyseven dollar GPS unit. My highly accurate $200 Garmin GPSs (plural) get map updates several times a year at no cost.
