I'm not new to this forum, but don't post a lot. I just traded in my 2006 STi for a used 2005 S4 manual to have something more comfortable. So far it was a great idea!

Down to the question, The car doesn't have nav, but it does have the Bose system with XM satellite. I already have a running contract with Sirius from my STi and was hoping to carry it over to the S4. As I found out it has the XM module installed. Does anyone know if it can be swapped to Sirius? I found the Volkswagen's and the RS4 have a module that you can swap out for 500 bux from the dealer, but if anyone here has Sirius and wants XM I'd be willing to swap. I'm in Milwaukee, WI and willing to travel. Thanks in advance.

Found this for RS6 so far http://www.audiworld.com/tech/elec115.shtml

Found the answer, it's possible.

Found cheapest solution....Cancelled Sirius contract, they waived the cancellation fee and I'm receiving my money back of extra months. Now to call XM and purchase with them. Don't matter too much since they're "Officially" merging in a couple of months. Thanks for the reply too though.
