yeah you have to buy the Sirius addon from mazda if you want that to work...it costs an arm and a leg though like around 400-500 i think.I just purchased an 06 mazda 6 sport. The window sticker says it has sirius compatable radio. When i press the SAT button on the radio nothing happens. How do i know if my car is compatable? I know i need to get the subscription but would like to make sure i have it.
If you have an 06 your radio is "sirius ready"...just needs a sirius unit.
Or you can buy a sirius unit from sirius for like $60 and install it
