No, there is no FL version for the Kona N (OSN) as far as I know and, from what I am reading elsewhere, there is not likely to be!
Anyway, my July 2022 vehicle which I bought in October was fitted with 2021 firmware so I updated it with the June 2022 version and then subsequently with the current one so I did the updates within a few weeks of each other and noticed the differing on screen instructions I got in the vehicle as to "switch engine off - update will continue in background" versus "Do not turn off the engine until update is complete" - maybe not the exact wording but that was the gist of the instructions.
Hence my original post. Maybe one version was updating more modules than the other.
Instead of spending time and energy messing about with different background sounds and cheapening some of the graphics they could add a few really useful functions. For example, actually incorporate some sort of over speed limit warning - that is, when the vehicle is at a higher speed than the limit the camera has recognised from a road sign then flash the icon or show your speed in amber or something! They could take a leaf out of the Mazda system on my wife's CX-30 - apart from the traffic sign symbols which actually flash with an orange halo when you exceed the limit the analogue style speedo actually has a red line marking the limit and a simple push of the "reset" button on the steering wheel will set your speed limiter to the posted value - plus or minus any offset you have selected in the vehicle menu. Simple, useful and very easy to use.
