With a NA “2020 Ford Fusion” and a build date of Dec 2019. I’d just upgraded used Ford’s USB based upgrade to go from 3.4.19200 to 3.4.20282 on the Sony/Navigation unit. After noticing my Maps Version was still “NA 118”, I accidentally googled onto Syn3 as slick way to update Maps. My primary intent is to update the Map data (not so much install v3.4.20351).
After configuring Syn3 to “AutoInstall”, I selected 3.4.20351 and Map 1.19 for NA - and then quickly stumbled at “Syn3 has set the install mode to Downgrade - DO NOT CONTINUE IF YOU HAVE A CAR MANUFACTURED in 2020! IF YOU CONTINUE AND HAVE A CAR MANUFACTURED IN 2020 YOU WILL BRICK YOUR CAR!”.
A very clear message!
I want to double checking before blasting away on my 2019 manufactured Ford: does Syn3’s “2020” strong warning apply to a “2020 Ford” sales year model with a literal build/manufacturing date of Dec 2019?
To err on the side of caution I would advise against reformatting your vehicle for the time being.
The issue with 2020MY+ vehicles is that Ford uses new displays in those which the reformat tool does not have drivers for. The tool therefore cannot initialize the display, and without initializing the display it cannot proceed with the reformat and leaves the unit bricked.
You can however try and identify the part number for your display which could help us to verify if it will be effected by the reformat tool. Unfortunately, this is rather difficult to figure out without actually taking the APIM apart and checking the part number (to the best of my knowledge). The only part numbers that are reported via FORScan or other tools is the part number for the APIM itself. You could just pull the part number for your APIM and based off of that we can make an educated guess as to the part number of your display (usually they line up with one another).
To grab the part number for your APIM, use the interrogator tool in the utilities tab of Syn3 as shown here:
Great approach/advice! I’ll pull the APIM part number with the Interrogator and see where the educated guess at the part number of the APIM display takes us! Getting late here, so will do tomorrow. Thanks again.
