C300 Lost all audio, help?!?!
Guys,
I have a 15' C300 4Matic with the Burmester system, I believe the smaller screen. Have had zero issues with it until recently. A couple days ago I have totally lost any audio. Both USB, bluetooth, radio, cd. No sound what so ever. When i say no sound I mean no sound. Like no hissing, no muffled sounds. Just plain silence. Wonder what could have happened. Anyone ever have this issue?

I assume the screen turns on?
only thing I can suggest is holding the CD/DVD eject button for a few seconds till it resets, everything will still b there dw.

The aux battery need to be replaced is all. You might have a failure with your aux battery but nothing too serious. Should not affect how the car runs, but a few entertainment items might be affected.

hi, did you fix the sound issue on your 300 ?
What was it ?
I have the same car with same Burmester. Already checked the Sirius module and Comfirt module in trunk. Still no luck.

Mine has done this several times over the last 4 years, all I do is turn the system off at the button next to the volume control on the centre console for a few seconds and then back on again, hope this works for you.
i have also had the auxiliary battery malfunction and replaced the voltage converter to fix this. If you are handy the voltage converter can be bought on line and fitted yourself. It takes about half an hour with detailed instructions on this site

you will need to do a water test from the car roof and most likely your roof channel is leaking as that water is what killed the amp.that water drains right on top of the amp. So buy those rubber bushings from mb directly and replace as well if u do decide to change the amp.

i had to replace the amplifier. It was $700 that I replaced myself. The amp is mounted vertically next to the rear light in the trunk.
