I think I have found (what I believe to be) a bug with the PCM4 on my 2018 Macan S. When using the < > physical buttons to switch through the preset radio stations it works as intended in every screen (Nav, Tuner, etc) however, when using Carplay and listening to the radio in the background, the < > buttons instead go to the next or previous broadcasting frequency (seek) instead of the next or previous preset.

I would like to know if anyone can reproduce this issue as I'd like to inform PCNA of this for it to be patched via a software update.
