For you to do that, you will need to remove the fuses for the CD Changer, COMAND/ NAV / DVD Player / Radio, Audio Gateway AGW, and the Voice Unit if it is equipped with one, for at least 10 minutes. Doing a soft reset for these systems will force the head unit to rest. This normally restores the systems to working order. Chances are the symptoms may return. If this happens repeatedly, a professional technician or mechanic can help check any updates for your COMAND / navigation unit.How to perform a soft reset of the COMAND / NAV Radio System.

Find the fuse box under the dashboard. Pry the side cover, look for fuse 26 and 28 and remove both fuses. The second fuse box may be on the left side of the trunk. Locate and remove fuse 6. Take out the key from the ignition and don’t turn on the car for at least 15 minutes.Take note: The fuse number will depend on the model of Mercedes-Benz that you have.

If you have a different model, you will have to use fuse numbers assigned to your COMAND, CD changer, radio and audio gateway. A fuse chart for your model can be found on your fuse box, use the chart to identify the fuses for these components.Fiber Optics TroubleshootingTroubleshooting the fiber-optic loop is the next step that you should do if removing the fuses does not solve the no-sound problem.
