Add satellite to 6-cd stock radio??
 

So I just picked up my 2011 GTS and it has the stock 6-cd stereo installed. I was reading the manual and it references satellite radio a few times and how to use it.

I can't find anywhere on what to buy in order to get satellite to run through the stock unit. I've looked online for parts and have had no luck.

I'm assuming that I'd need to get a Sirius tuner and run it into the back of the stock headunit.

Can anyone point me in the right direction on where to go to buy the parts.

Thanks!

do you have sirius unit?
you can find it if remove glove box cover.
unit install in rigth.

if you don't have a unit, you need check whether it is possible to install it.
installation must be:
wire with connector to the sirius unit and antenna connector,
if you have all it you can buy srius unit (8701A219 part number) and install.
if not, you need buy parts from car with installed sirius unit

So i looks like i have the wires, I found a used 2012 rally art module online for about 80$ that i may order.. can i just plug it in and it will work? From what i have read it sounds like most models use the same module.
