I bought an '05 S4 just before Xmas with Premium sound/XM and to be honest I think that I'd rather have not got it.
I live in West Los Angeles and keep experiencing dropouts and loss of signal, in fact last week-end I drove to San Francisco and for the best part of 200 miles on I5 I had no signal. I took the car into the dealer and after a day they couldn't find any fault codes on the unit and the antenna checked out OK, although on a test ride they experienced the drop-out. Eventually,with the help of Audi's Tech line (only one guy knows this stuff) the y found another diagnostic and reset something. Now it seems better (after 1/2 a day) but the jury's out as it still get s "no signal" on my communte down PCH through Malibu.
If the radio is OK and the XM reception is as poor as I've experienced Iwould say go for some kind of MP3 player, IPod, Phatnoise etc etc.
