My Sirius radio module is always doing that. Is there a fix? I am in open areas unrestricted to the sky. It seems after I've driven the car for a while it works better but is really weak.

I am not opposed to cracking open the module to look for something loose or unusual.

It's not in the fiber optic connections. I already tried to troubleshoot it there. If any are loose or disconnected, nothing works in the MMI.

Any thoughts from the pro's?
