2002 Q45 Sirius Interface - Need help ASAP!!!

[usmcq45]

What is the best way to install a Sirius unit to my 2002 Q45? It has the CD player in the glove box and the stereo doesn't have a "SAT" button on the stereo.

Is there a economical way to update the speakers without removing the stock head unit or amp?

Thanks for any info!

Before a certain VIN # which is identified in a TSB, it is not possible to add a satellite radio module.

Wow, someone's still actually planning to install a new Sirius receiver? I'm stunned. Dropping all three of mine this month thanks to the rate increase and recent channel slaughter on the XM side.
