W204 Audio20 loss of audio after an hour

[DrTroy]

Hi, have a 2008 C200 with an Audio 20, after one hour of driving there is no audio from the radio, cd or bluetooth. However you can still interact with the display. If you stop the car for a few hours and start it back up the audio can now be heard...

Any ideas? Is this a common fault? Can not seem to find much about it..

Thanks in advance

Doesn't happen on my Audio 20, although I have a UMI linked to it as well, but certainly sounds (or doesn't sound ) a bit odd
