My 21 is on 3.4 21194. Nav version NA 2 20. Yesterday I went to the Ford update website https://www.ford.com/support/sync-maps-updates/ and discovered that for my VIN I have a Nav update available. I downloaded the files to my laptop and was going to install them once I got a new USB 3.1 flash drive I have on order from Amazon. However, looking at the dates of the downloaded files I have my doubts as to whether this is an actual update. Does anyone know if there is a newer version of the Nav database than 2.20?
