How can I play music in my car from my iPhone without an aux port?

I have a Ford Ka Zetec 2011 and it only has a USB port and no AUX. I know I can plug my iPod in and it will play random music, as the screen shows as connected so can't choose music, but I wanted to know if anyone knows a solution so that I can play it whist being able to see the screen and chose songs or connect my iPhone to play music?

No

Can't you just connect the iPhone or iPod as USB mass storage like you can with any Android phone (or frankly any dumb-phone/flip phone made in the last 10+ years)? Please tell me you're joking and Apple isn't really this sh*t.

Cast a magic spell on your head unit to create an AUX input.

Lol well then get a HU with an AUX input.

Simple as that.

Take another look at your owner's manual.
