Tried updating my sync3 and got an error message

About the HUB, I’m talking about the USB HUB in the car. For a 2016 car it needs to be replaced to be AndroidAuto/CarPlay/Sync3 3.4 compatible. More information about the required part number can be found here → Media Hub, CarPlay Compatible - 2015-2020 Ford/Lincoln - SYNC 3

About 2.2.17011, take this post as a guide to ensure Android Auto / Car Play works before moving to 3.4 → 2016 Mustang Sync3 1.0 updated to 3.0 and no Apple Carplay! - #10 by SaNdMaN
2.2.17011 has been flagged as one of the “AA/CP activation build”, and since you can’t go back from 3.4 to 3.0 (or earlier), my recommendation is ensuring AA/CP works on 2.2 / 3.0 before upgrading to 3.4.
