What map version did you download?
The license for the latest maps on this site will not work with your vehicle with autoinstall, as the newest maps are VIN/ESN locked, and you cannot use reformat on a MY20 APIM. The Ford version maps will not work since you have a replacement APIM.
You would have to use reformat mode to install the latest maps, but you have an L series APIM so that is out of the question.
LJ6T-14G532-MCM (lu5t-14g371-ckc)
Run the Interrogator Utility in the Syn3 Updater and post it here.
The newest maps that will work for your APIM are the NA 2.20, which do not have the license restriction.
