My car has a staggeringly bad UI design choice - the cancel active navigation the control to do this only appears when you hold your finger close to the screen. Pretty much every time I want to do this I am flummoxed as to "Where did the button go" - before I eventually remember.
The navigation system is good - I prefer it to using my phone and CarPlay but that design is terrible.
Is it a VW? I had a VW with a proximity sensor like that. I didn’t use the in-car navigation, but it did that for the favorites on the radio. They only showed as I moved my finger close to the screen.
