Sirius radio compatibility for 2004 X3 (build 02/2004)

[bennette4796]

Hi, I was hoping that one of you might know if the 2004 X3 w/ NAV can ever be made Sirius compatible with a 02/2004 build date... The Sirius compatibility chart indicates that it can't, but I am not sure if this is because of the NAV software or the radio unit itself.

I have a BMW Sirius unit, all hooked up with power, a recently updated NAV software level of V29.1, and still cannot get my radio to see the Sat tuner. I have doubled checked, and my Area is USA. The radio cycles between AUX and CD, but no sound on either, and no SAT mode. I wired this with an extension cable from the CD changer connection in the armrest.

I am hesitant to spring for a new radio module without confirmation that this is the problem.

Any suggestions?

Thank you, EileenB
