I would advise against using kits from China to upgrade SYNC 2 to SYNC 3. Even if they claim to work, many of these kits are sourced from junk yards in the USA, where they salvage broken screens, damaged main boards, or cars affected by accidents or floods. These components are then rebuilt and shipped out. Additionally, a lot of these kits use aftermarket USB ports, which can lead to further issues.
The fact that these kits somehow work can be seen as an achievement, but there have been numerous cases where people have been disappointed and wasted their money. Unfortunately, there is usually no way to get a refund or recourse. That's why I always recommend keeping the factory screen and upgrading to CarPlay. The original parts for a Ford Sync 2 to Sync 3 upgrade can be quite costly, but it's a safer and more reliable option in the long run.

If you are lucky, and there is no problem with your screen, you can probably fix your issue by changing USB cable and USB port.
