I own an older Lexus RX350, which I upgraded the stereo head unit from an outdated cassette/CD player to an Alpine unit with Android Auto/Apple Car Play. While it certainly packs more features, needing to look down to do things like frequency search is inherently dangerous because it takes my eyes off the road. Compounding the matter is if I hit a bump, and it makes my finger bounce and I end up hitting the wrong button and spending MORE time looking at the screen to make a correction. I do my best to use voice recognition while in motion, but sometimes it just doesn't work. For routine items like fan, temperature, volume, etc, hard buttons make sense. But things like updating maps are much harder to do via hard buttons.
