I didn't want this to get lost in the thread for the swap here and thanks to @Ccso77 for posting up the info!

Upgrading 2015-2016 Uconnect 8.4 to 2017 and newer...

Everything was plug and play on my 2016 A8 Hellcat. Only two things to be aware of:

2. Intercooler Coolant Temp doesn't register. Not sure if this is a software issue or sensor issue. I'll be going to a Redeye supercharger next month so we'll find out if it's a sensor issue then.

Gent that follows my channel sent me a TSB on the IC Coolant Temp gauge not showing. Apparently it's a known problem with the multi media unit software and supposedly is being looked in to. Anyone new or old that swaps their radio will likely have this problem. Several people contacted me that had to replace their head units in 2018 and up cars and their IC temp gauge is blank.
