For a 4" to 8" upgrade you will need a new FCIM (button/sceen surround panel) as well as the APIM and APIM Screen. The USB hub should be fine since it is a later model vehicle. You can verify the hub part number here:
Media Hub, CarPlay Compatible - 2015-2020 Ford/Lincoln - SYNC 3 - Ford / Information - CyanLabs Official Community
You will need FORScan and a good adapter to program the APIM and FCIM. Also, there are a few folks on this forum and Discord who may have experience with the Ecosport models. I don’t know if there is anything special to look out for…
Look for a K-series APIM and screen for the retrofit. This will fit your vehicle and support the vehicle features best. The part number will be something like Kxxx-14G370-xxx,. Here is an extract of the hardware database listing the K-series with NAV…
