2013 E350 Cabriolet Sat Radio and sound problems

Question by giannatj posted 6 months 2 weeks ago in E-Class

My satellite radio operates normally for about 10 minutes and then shows "device unavailable". All other Command components go silent. They're running but with no sound available. When I restart the car after a rest everything works again for about 10 minutes. I suspect the Satellite radio module is failing but I can't find it in order to test or replace it. Can anyone tell me where to find the module in the car and how to get to it?
