Xm to Sirius convert question

I have been an XM subscriber off and on for almost 8 years now.
I recently bought a VW that came with a built in Sirius radio. I would prefer to just subscribe the radio in the car and am having a heck of a time. I really only listen to talk on XM and especially the Virus channel. I noticed this wasn't on the Sirius preview and when I called to ask about it on the Sirius customer support number I have gotten 3 different answers. Ideally I would like a talk only (including the virus) option with the internet option. I know this cant be done but what is the cheapeast/closest thing I can get to this? That is, the virus on my new radio, and online access.
It seems like keepong the xm sub may be the way to go but I hate to have to use another radio in the car that has Sirius built in....seems stupid.

Does Volkwagen offer a Sirius option with your vehicle? If so, you can probably make a swap.

That said, if you can't, the only way to get XM on Sirius is to pay for the "XM premier" package and that isn't a cheap option.
