Look for a stereo plug aux-in port on the car’s stereo. You can get a Bluetooth receiver that will plug into that if there’s no usb input built into the car. This will let you listen to music, audiobooks, podcasts, etc from your phone using your car speakers.
This also works with turn by turn navigation prompts that come from the phone.
Just remember to keep your phone plugged into a charger on your trip so that using it this way doesn’t drain the battery.
Anything but brutalism.
