Yep. You're right. Any BM53 Radio from 9/2003 has the updated s/w to support Sirius and would work with your NAV. It also allows the CD Changer to be daisy changed to the Sirius receiver so you can have both.
The latest part # for BM53 is 65.12.6.976.961
This part also includes support for ID3 tag display when used with the latest (from 9/2005) BMW OEM CD Changer as well, so if they fit the very latest BM53 that will be a nice upgrade for you.
Cheers, Adrian
