Perhaps you need to refresh the Sirrius module

Refreshing your radio is like restarting your computer- if something is acting up, refreshing your radio should fix it.

If you're near your radio now
The refresh signal will be sent from a satellite, so make sure your vehicle is outside and your antenna has a clear view of the sky.
Turn your radio on and tune to Channel 184 for Sirius radios or Channel 1 for XM and SiriusXM radios.

If you're near your radio now, just choose Send a refresh signal to this radio from the dropdown menu in the My Subscriptions tab, then click Send Activation Request.

If you're not near your radio
Call the Sirrius automated activation hotline when you're ready at 855-MY REFRESH (697-3373).
Make sure to have your Radio ID/ESN handy.
Follow the instructions from their Automated Activation Hotline to have a refresh signal sent to your radio.

The other thing is that the Sirrius module is bad and you will need to take it into a BMW dealer to have them install a new module.
