94 E320 Sportline sedan 86 190E 2.3 16V sedan 04 S430 Sport
Greetings, just picked up a really clean 04 S430 to add to my collection. The radio display shows a "Sirius" button on the radio menu, but when I hit the button it does not display the XM radio code for activation. So my question is, are these radios already equipted or do I have to get a "chip" added to the unit in order to activate the Sirius radio? Thanks.
