COMAND 2.0 cuts out

I'm having a problem with the COMAND 2.0 unit. Every couple of days, while listening to Satellite Radio, I hear a PFFT and the sound cuts out. The message on the screen says no satellite radio. I try to select FM/Am and no sound.

I turn it off by pushing the power button, then turn it back on and things are normal again for a few days..

Any ideas?

beater with a heater
sat tuner or antenna would be the problem, or the connections... i would try an aftermarket sirius antenna for a few days then if happens again.... look for a tuner in the junk yard

Thanks Jbondox,

found the hidden diagnostics menu for the COMAND Unit.

the first fault was N1111 followed by a type of 0x01F8 which if I read correctly is the voice recognition module. The CNT was 21.

the second fault was n1112 followed by a type of 0x0000

Any idea what these mean?
