Update:
I upgraded my 2016 Explorer Platinum to Sync 3 using a module I bought off Marketplace (seller said it was from a 2019 Fusion, but I think it may be from a Focus). It had Android Auto and CarPlay, but factory features like massaging seats, heated steering wheel, etc., were missing.
I grabbed the VIN-based As-Built file from Ford’s site and used Forscan with an extended license to flash the APIM. I got a warning about block lengths not matching but continued anyway. Flash was successful, and now most factory features are back.
However:
TPMS pressures don’t show on the dash (not sure if they ever did).
Getting some voltage-related DTCs — we had a weak battery before the swap, now charging it and planning to clear codes.
Currently running Sync 3.0 — wondering if it's worth updating to 3.4.
Any tips on restoring missing features, clearing DTCs, or safely upgrading to 3.4?
This is the APIM part number I installed.
