The only thing that keeps me motivated to use the audio jack is because my old car still has an old stereo and I use it daily, and I am too lazy to use dongles lol.
As a matter of fact here is a pic of a disc that my girlfriend bought recently because it was on discount, and we tried it in the car for the first time ever! (We also don't usually buy discs, this would be the first time in more than a decade).
