Hi. Is it possible to just redownload navigation? I had to down grade to 19101 and lost my nav and if i upgrade to 19274 with nav will I get it back?
thanks.
Downgrading removes the map, so yes if you upgrade back to 19274 will reinstall the map, providing you select maps on the app.
Great. thank. hope it works!!

Downgrading doesn’t remove maps
My apologies, I thought it did. I thought my Nav didn’t work when I downgraded. Must be getting confused.

Excellent 
glad it worked out
how do you do map upgrade only if I am on SYNC3 v3.0.19205, thanks
You can’t unless you source all the files your self.
damn, okay wont know how to do that lol
Ford has these map only updates for v3, but their ESN specific. They say their VIN specific. I’m curious if they work on other vehicles
This is what you get when trying to install on a car with the wrong ESN. I wonder if I can just copy the files over and make a new auto install file? 
Nope. You need a license file tied to the VIN.
Interesting though Sync 3.4 and the latest NA maps 1.19 do not have ESN signature check
Ciao, mi puoi dire quale è la versione della mappa che hai aggiornato e come hai fatto ad aggiornare solo le mappe? grazie
Hi, can you tell me what version of the map you updated and how did you update only the maps? Thank you
This is an English speaking community forum…
For Italy, the latest maps are EU F10, and you can use the Syn3 Updater to upgrade.
I’m running F9 maps. this is what came with the car. I got an official update from ford for the map voice but it won’t load. All I get is mem err 01.
Unfortunately, Ford’s assistance is very poor
