I have an 04 with the mach460 and added an auxillary input to the satellite radio port. When I push the 'sat" button it reads "aux" and runs to a 3.5mm jack that I can plug into any ipod, iphone, etc. I cannot for the life of me remember the part number or where I got it other than I did a google search for the part and found the website. I know that your radio has to have satellite capability in order for this to work.
