I have a 2004 Ford Mustang with Mach 460 which is satellite radio ready supposedly. When my dad originally bought the car he didnt get the sirius installed, but I want to now. Anyone know where to buy it from?

 

if your car is indeed Sirius tuner equiped it should have some numbers, check your manual. In any case, after you get the tuner numbers all you need to do is go online to the Sirius website, register, pay, and then turn on your car and start enjoying the sounds of Sirius!
