I got my wife an 06 X5 this weekend. Did a ton of reading on here. It has a Nav system IV 27software (might update this to ver. 32), with no DSP (for this kind of car expected a much better sounding system, even though it's not the DSP version). Anyway, it didn't come with a CD changer, and I can easily get one from ebay. I have the 3 pin IBUS and 6pin adapter in the back ready to go. The dilemma is that my wife would like to have XM, or Sirius as she did in her old car. From my reading here, seems like the easiest and cheapest solution would be to get an Intravee II, get an alpine CD changer, and get a Sirius Adatper as well. She doesn't really care about hooking up her Iphone, but CD's are a must. What I need to know is, what CD chagners can I use with the Intravee? Any model Ainet Alpine CD Changers? And also any Alpine Ainet Sirius adapters as well that I see on ebay, or specific models? How would you select between devices on the Intravee menu? Also, going with the Intravee, how does that effect the nav screen display? Can you play songs, and switch away from the Intravee screen, and go to the full Nav map display? Any advice, would be appreicated.

Thanks in advance..
