Sync 3 Reinstall questions about programming

[darthlung37]

I have a 2019 mustang GT premium automatic that originally came with the sync 3, however i swapped it out for a different unit because i disliked it greatly. I plan on trading it in and want to reinstall sync 3, so i purchased a unit from a 2016 mustang gt with nav. My question is do i need to program it differently or can i just plug it in and go?

There is programming involved. You will find a lot of useful info in this thread: https://www.mustang6g.com/forums/threads/sync-3-swap-its-all-in-here.82973/

Were there issues with 2018 and newer being slightly different than pre 2018 head units?
