I know some of the newer WRX/STi's radios have built-in aux jacks in the front. Does anyone know which years have these?

Second question, is there one I can use to directly replace my 2004 radio without any fitment issues?

Thanks in advance.

Edit: Nevermind. Found this thread for center console replacement: http://forums.nasioc.com/forums/showthread.php?t=1252301&highlight=radio
