Hey all Apologies if this has been covered but is there any way / source to get the latest update for the f250 nav box? Ive been out of the game for a while and never done an update since I bought this a while ago but think its time to update the maps but no clue where to go to get the update 2022 maps? Cant seem to find any mention of this on search on the forum either so any help would be greatly appreciated. Thanks in advance peeps
