Update: ***** BMW states that ALL 2003 head units are Sirius compatible. So for units built in 2003 the yr from the week/yr digits are the important ones i.e. "03" the software version is not important. However for any MY2003 head unit manufactured in 2002 the SW version needs to be "50" *****

To access the headunit software version number and week/year build of the headunit:

With the ignition off, turn on radio.
Hold "m" key for ~ 10 seconds, until the unit serial number is displayed.
Press the key under the "+"
The week/year build of the headunit and the software version is displayed. The software version is the right two digits.

Sirius ready:

A software version than or equal to "50" and "02" in the year field for head units manufactured in 2002

--- OR ---

"03" in the year field for 2003 built units.

This information is also on a tag on the bottom of the head unit. Get the seller to take a pic of it.
