What is my best option to get an xm radio on a 2007 A4 2.0 without a NAV; is there any possibe way of getting a tuner that integrates with my current factory stereo, I know audi is only dealing with Sirius now. I saw a tuner on ebay but am not sure if this will work with this car. If not what are my other options without changing the entire radio; I would rather not have to use an FM modulator.

 

The car should still be prewired for the xm. And they are officially only dealing with sirius. Most dealers still stock and install xm.
