Recently updated from 3.4 Build 19101 to Build 20196 using Syn3Updater and all appears fine, but my heated seats no longer show up on the home screen.
They DO show up in the secondary climate menu.
I checked with FORScan and APIM settings are as follows:
7D0-01-01 xxxx-xxxx-x*xx is set to 3 which should be Heated Seats only.
I do NOT have an FCIM with hard buttons at this time.
