You can get what you want with a Audiovox Mediabridge. You will have bluetooth, USB, AUX and Sirius radio if you purchase the module. Not a difficult install and Dice will help you if you get stuck. You will lose your CD player. I have had a mediabridge for a very long time. Works great and everything is controlled with existing buttons.
