I have updated my 2018 Navigator from 3.0.17302 to 3.4.22048 and it didnt work well for some reason. The screen was not full screen and Nav didnt work. Any idea how to downgrade back to the official version? cant find the file online and lincoln support didnt help much. Thanks
As per our multiple notices you can not downgrade back from 3.2,3.3 or 3.4 to 3.0
Sounds like you had a non standard theme installed and you are now using potentially a 10" theme on a 8inch APIM or vice versa, maps not working is due to something you have done wrong.
Please provide your log file, there is a reason we ask for this. without this log file we have no idea what you have done, what install method Syn3 Updater used, what packages were selected, etc
I have master reset and it stayed as a small screen. I must have chose it by mistake but its no big deal cause I never use Nav. I have ordered an OBDlink from amazon just incase. I tried to go into test mode and change the theme to Lincoln MY20 10 but the screen goes black and becomes un responsive.
This is a typical behavior for the Sync 3 10" displays upgrading from Sync 3.0 to Sync 3.2+, especially version 3.4. The themes have changed and the asbuilt coding needs to be adjusted for the 10" screen. This is easily done with FORScan or UCDS. When you get the adapter let us know…
That test setting is not persistent. Since it is set wrong in the first place, it will do that. It needs to be set properly and then master reset. (Video driver thing…)
I did the same update and had zero problems on my 18 Expedition. I am guessing it is an AsBuilt issue they have mentioned. I have not seen problems in the Expeditions, but I am also really only familiar with mine. Log files look good also so it has to be AsBuilt.
@waez once you get your adapter if you cant get it fixed let me know and I can share my AsBuilt with you. You can see if my settings work for you to fix it.
