Sirius / XM Radio wont activate - B7 S4

[Blue S4]

I have a B7 S4 and tried adding the car to my Sirius account (currently have a 2010 Volvo XC70 with their service). On multiple, multiple occasions I have tried going through the entire process of getting the signal activated. I have followed all of the steps required by Sirius, I've spoken to technical support on 10+ occasions, waited hours, days, tried everything. I even found a thread detailing how to add a dummy ESN with them to trick their system, and still nothing. Nothing works.

I know the car was hooked up with the prior owner because all of the presets are still saved. Sirius advised there is nothing else I can do, it HAS to be a problem with the car/radio which I find very hard to believe. The FM signal reception is ridiculously good, and the factory radio has never had any problems. I'm not taking it to the dealer as they recommend.

Any suggestions? Anything you can advise that I check, or any procedure I can try to complete? I'm on my last leg and am tired of calling in and dealing with their sub-par customer service.

Do you get the preview channel playing? Or nothing at all when setting the source to Sirius / XM? Might be worth just disconnecting the unit in the trunk, then reconnect it, then try activating.

[Blue S4]

Nothing, just a faint hissing sound. No preview channel.

Any DIY or diagrams on where the unit is located?

[naiku]

It's in the trunk, behind panel on the left.

Does the car have an ipod or aux adapter?

[Blue S4]

No it does not. I just ordered one though because I have just about given up on XM. No point in paying for a service I cant use.

[Christian@enfig]

My guess is that there is already a connection behind the radio that is killing the sat audio.
