Are you having trouble with a non-working radio on your Mercedes-Benz?

We have listed down common issues with the Mercedes-Benz COMAND system, including problems with

– the main unit

-radio stuck on Mercedes-Benz logo

-radio shuts off randomly, turns on and then off

-radio powers on but there is no sound

-COMAND will freeze

-radio panel doesn’t turn on, and;

-Audio Gateway drains the car battery

How to Fix Issues with the COMAND System

The most common solution to fix any of these issues is to try to perform a soft reset of the COMAND unit. 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 Mercedes Benz repair 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

1. Find the fuse box under the dashboard. Pry the side cover, look for fuse 26 and 28 and remove both fuses.

1. The second fuse box may be on the left side of the trunk. Locate and remove fuse 6.

1. 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 Troubleshooting

Troubleshooting the fiber-optic loop is the next step that you should do if removing the fuses does not solve the no-sound problem. The fiber optic cables are used to transmit the sound signal of your Mercedes-Benz between the different units for better sound quality and faster transfer rates.

When one of your components goes down, your COMAND will stop functioning. You need to figure out which component is defective by bypassing each component until you find the problem. The Audio Gateway is the brains of the Mercedes-Benz COMAND system. You will need to have an authorized Mercedes-Benz service technician replace the whole unit if AGW is defective.
