I pulled out the AVN fuse to see what kind of functionality is lost, but I did not discover anything that was lost. Auto parking, memory seats, blind-spot detection and auto lane assist all worked fine. Even chimes did not stop working, it seems like Optima has separate speakers for that, probably something to do with EU safety regulations.
I wonder if these CAN buses are used in other regions than the EU or if they are used with KIA connect, don't Know, it is my best bet. I will swap AVNs and see what happens, will update in a couple of weeks.
