If your phone has that. And if you run a wire to this in your car and keep it tidy.

Oh, then you need to run another wire for the audio. Whereas with the ancient 30-pin iPod port, you got an audio line out AND power in. And the cool thing about that one is that it was a true line-out: The volume control didn't affect it, so you didn't have to dick around with the volume on two devices (the player and the car radio).

I bought the Lightning-to-30-pin adapter from Apple, and it duplicates all of that. You get the audio line out and power in. A cheap Y cable with USB for power and 1/8" plug for audio solves everything. As far as I know, it's the only solution that Apple has ever sold for a problem it deliberately created. And I doubt anyone, statistically, is even aware of it.

I think the vast majority of people just use Bluetooth in their cars. My car is from 2016 so it has CarPlay. I bought a $50 wireless CarPlay adapter and pulled the cable for a MagSafe dongle through the dash and now I can just plop my phone down so it's held in place, it charges, connects to the car console, everything is super handy.

Lots of cars don't have Bluetooth for audio. For example, we have a 2013 Mini that (somewhat inexplicably) supports Bluetooth for phone calls but has no provision at all for music over Bluetooth. But it does have a auxiliary audio input.

Neither of the other two vehicles in our household have Bluetooth at all, but they both have aux inputs. Bluetooth is a shitty workaround to intentional, anti-consumer stupidity. Just as almost every car (even cheap-O rental cars) integrated auxiliary audio inputs, Apple removed the audio output from their best-selling music player (the iPhone). And when gutless consumers allowed them to get away with it, everybody else followed suit and now we've regressed decades.

Twenty years ago I built an iPod dock into my car, into which I could plop my iPod (and later iPhone) and get power into the phone and audio directly into the stereo system. The phone charged, and delivered good audio quality. As a bonus, it did so without the need to dick around with two volume controls, since the 30-pin connector had a proper (fixed) line-level audio output that didn't vary with volume adjustments on the phone.

This is a level of convenience and performance that very few people enjoy now, and that is pathetic. Manufacturers have intentionally degraded so many of our consumer-electronics experiences with no payoff for us, and very questionable payoff for them.
