I found out that KCE21- refers to an internal Kia system bulletin for 2021, KCE20 for 2020 and so on so this code likely refers to some type of internal Kia knowledge article on a Kia system, that print out letter is maybe a direct printout from that system?.
Also while chatting to a Kia technician today, I found out we as owners can update EV6
navigation and head unit
software ourselves using
https://update.kia.com/EU/E, however, please use this will caution if you haven't done something like this before as I understand from ICE BMW & Audi USB updates in the past if it goes wrong, it's a trip to the dealers to fix it and maybe a cost involved and since these are basically computers, it could even lead to your EV not being able to drive there to get help..... And once the software is on, it's on, no rolling back to a previous version, so I have been told.
The question is... Does this update include what we are looking for, HVAC fixes?. I can see anything about that... mostly UI changes in the head unit UI, map changes, radio fixes etc. A whole list of stuff from
Notice | Official Kia Motors Navigation Update Website
It may be likely those who have their cars already have this update? those whose cars are on order and have been on a ship to the UK since...September? have not had this update yet. Maybe just maybe looking for updates is included in the dealers PDI checks and we would get it anyway.
