It's probably true that once you (more or less) need a screen for a decent backup camera and most people like a screen for at least GPS, it must be pretty tempting to at least think about what physical buttons can reasonably be eliminated given that the touchscreen is a given. And I do think a lot of designs go too far.
>and most people like a screen for at least GPS personal anecdotes, but the vast majority of me being a passenger to someone else's driving, they all used their mobile device for GPS. even the couple of cars i owned that had a nav system, the GPS came from the mobile device. it required their app to be installed to input the destination, making the internal unit just a second screen for your mobile.
Mostly, I just use my phone. It's simpler and faster. My cars are too old for carplay/android auto, and my experience with android auto was that it was worse than the phone in a clip or a cupholder, but carplay seems nice. For longer drives to unfamiliar places, I'll put the address in the car too, sometimes the phone gets tired of listening to GPS.
