I have a 2016 kia and the usb plug in doesn't work

[AC Question]

IT tell me when I plugged in my usb card to charge my phone it say un supporting

The USB is not for charging. It is to use your phone as a storage device to play music through car audio

And be aware that these USB ports don't always read Android devices well. They might be intended for music stored on a USB flash drive, not a phone.
