I’ve already tried quite a few things. I reset all network settings, removed and re-paired my iPhone 17 Pro Max with the car’s infotainment system, updated the infotainment to the latest version and even disabled all widgets.
As mentioned, many people across the country are reporting the same issue and the common factor seems to be cars from the VAG group (Seat, Škoda, VW, Audi etc.). When driving past certain spots, the audio begins to stutter, then the frame rate drops sharply and finally, the iPhone disconnects completely. The car then immediately tries to reconnect, usually without success for about a minute.
