Ordering a 2007 A4 Avant 2.0. Have a few audio questions that I can't seem to get a straight answer from the dealer.

1. Is there a large audio quality difference between the base Symphony II stereo in the A4 versus the Bose Premium system? I have heard mixed reviews of the latter and wonder if it is worth the extra grand.

2. Is it possible to have integrated Satellite radio through the head unit if you do not purchase the Audio Package (which includes the Bose upgrade). Essentially, is satellite radio readiness alone a stand alone option? I need to get satellite radio, but in looking through the A4 documentation, it seems that you have to buy the Audio Package to get it.

3. Is there the option of an auxillary audio jack for ipods? If so, how much is it?

Thanks very much.
