The AUX port does not work, I want to listen to my Iphone but not connection.

What is your question?

Any suggestions to listen to the Iphone and suggestions on replacing the radio to be up to date for ports and blue tooth to connect my cell phone. Also, I hear a noise on the front tires making a humming noise - I just bought the car second owner. I took it to the dealer ship and they want to replace all four tires. I was wondering has anyone had that problem?
