Hi DaMiFo. With all due respect (and I mean that), if read properly, the information I provided is correct. However, as has happened in the past, you are misunderstanding what I wrote and therefore discussing different situations than what I was discussing.
For example, in your first example: No, we actually can not download the same SYNC 3 update "...as many times as you want". This issue has occurred many times with owners who downloaded a SYNC 3.0/3.4 update, had an unsuccessful installation, were advised by us to try a clean download and installation, but discovered they could not download the update again, because they deleted the files from their computer and did not save the email which had the file download link. And once successfully downloaded, the file is usually not available on the SYNC 3 update website.
In your second example: I was clearly discussing SYNC 4 OTA update capability and the ability for SYNC 4 to download and install OTA/on-the-fly updates to the PCM/TCM/and many other vehicle systems. Both capabilities which are far in excess of SYNC 3 capabilities. And even if a vehicle owner upgrades their SYNC 3 Fusion Sport to SYNC 4 modules, that formerly SYNC 3 equipped Fusion Sport will not be able to receive any downloads via OTA, nor download SYNC 4 updates from the Ford SYNC website, since the VIN will not match the SYNC 4 equipment. In the same manner that SYNC 3.0 vehicles that were upgraded to SYNC 3.4 can not update via the Ford SYNC 3 update website.
In addition, is there even an official/factory Ford SYNC 4 update website available for manual downloads and installations via USB in existence yet? https://www.ford.com/support/category/sync-and-technology/ford-power-up-software-updates/
Not everyone understands this technology, and the major differences between SYNC 3 and SYNC 4 as well as you and some members here do. So helping others to understand what are in my opinion major limitations to this SYNC 4 upgrade, is not a moot point. Again, in my opinion. If you think it is a moot point, you are entitled to your opinion. But the facts are still the facts, and I do my best not to inject my "opinion" into factual discussions. And if/when I do, I clearly state it is my opinion.
DaMiFo, again, with all due respect, if you believe a SYNC 4 imposter vehicle will ever be able to receive OTA updates (cellular data, not WiFi), and/or download SYNC 4 updates from an official Ford SYNC website (not third party websites), I would be all eyes to read your explanation as to how, since not even SYNC 3.0 to SYNC 3.4 swapped vehicles are able to do so.
For the umpteenth time, I am not telling others not to perform this upgrade. Only providing correct information as to the major limitations of this SYNC 4 upgrade for those interested. Everyone is free to do whatever they wish with their own vehicles. Therefore, the information I provided is correct concerning the subjects I was discussing, not what you mistakenly believed I may have been discussing. And if what I actual wrote is properly read, and we can stick to those subjects I was clearly discussing and not get off into the weeds, it would save us all a lot of grief.
Hopefully that makes the information I was trying to provide more understandable and we can move on. Especially since the reality is that virtually nobody will ever actually perform this SYNC 4 upgrade.
Good luck. 🍻
