Aux cord won’t work with my 2017 Hyundai Accent base model (not GL!)?
The aux port in cars is analog. You patch the headphone output to the car's aux input, unless the car's input is digital, which TRS plugs are not.
Go to a Hyundai dealer.

Hi with most cars it is the usb sockets which make the sound come out of the radio input. so the power cable is more likely to work than the aux input.
