Help please: 2003 X5 needs AUX and Sirius

[DPX5]

I think I have my answer but just want to throw out my specifics so I have good information.

What I have:

2003 X5, 3.0i, Standard one CD biz CD unit and standard radio (head) unit.

NOTE:
The CD player will not play data cds (mp3). As I understand, 2003 cd's should have this functionality. Checked my door and my born date is dec 2002.

First question, is the born date the issue ?? Since I have 2002 born date does that mean I have the older radio ??


What I want to do:

I want to add sirius
I want to add aux (via the BMW aux cable)


Siriu questions:

In is possible that my X5 is ready/cabled for Sirius given its year ??

In this thread, it suggests that one must upgrade to a 2003 in order to get sirius. Since mine is year 2003 am I good or does the b/o date mean that I need all of this too ?

AUX question:

Forget sirius for a second. What do I need for BMW AUX connection only ?

It's my understanding that I need the correct part which has the port the AUX connection. Do I need a specific radio or business CD or cabling??

Would I be correct in assuming that since I cannot play data CD's that I do not have the required part(s) that the AUX cable connects too (given that the connector was supposed to be eith b/0 2003 models)??

Thanks in advance
