As the owner of an extremely great home system, I don't expect anything close in my vehicle, but do choose the best in factory installed systems. Integrated makes sense; after market only invites theft. As a classical lover, XM/Sirius is my choice most of the time. I look at it as an opportunity to hear music I don't already know, as as well as enjoy music I do. Granted, it is not the best FI. For the best, HiRez files from my connected iPod/iPhone can be wonderful and even thrilling!
