Built-in car infotainment, generally speaking, sucks ass (and not in the fun way) compared to carplay and android auto. Bluetooth audio in my case will randomly drop connection and default to AM radio.

Disclaimer: I haven't had an iPhone since the 6s so I don't know how the carplay experience compares to Android auto.

In my 2017 model vehicle, Bluetooth audio streaming is awful because the quality is noticeably worse and there’s a mysterious fade-out / fade-in when one song transitions to the next making it hard to listen to continuous albums (such as Random Album Title by Deadmau5, as an example). Seriously it’s the only Bluetooth playback connection I have ever experienced where that happens and there’s no way to fix it (common complaint among owners of this vehicle). What’s more, the screen is larger and has a nice dashboard for navigation, now-playing, and turn by turn directions on one big screen making it significantly easier to control the phone while driving. Add to that the lack of distracting apps available and no chance of accidentally tapping other apps makes it feel more focused and safe. My only gripe is that despite being WiFi enabled, my vehicle does not have wireless CarPlay so I have to plug in a cable after I mount my phone. Small price to pay though, after all these years of a significantly better experience.
