Great video - thanks for sharing your problem solving with us. I will order a jumper and go through the process. One guy on a just answer site had the same problem. The connector pins to the media module had CORROSION on them - he cleaned up the pins and it’s working again. You may like to check the pins for corrosion on yours (sounds like a very common Mercedes problem).

Yeah Brother. I have fixed my no-sound issue based on your video. Thanks. 2011 E350.

That is correct! With fiber optic there is no negative or positive wires. Light has to travel through the wire and go back around to the other wire.

Sounds like your cd driver is faulty. You definitely need a new head unit, since the cd is “ built” as one unit. There is no way around this. Also I want to remind you, that most communications module controls the Xm, weather band, radio, Cd and The Bluetooth. When I was playing with this module those are all the sources I didn’t get Audio from or the functions would simply not work.

Excellent video, very helpful to start my troubleshooting. I have the same issue, no audio from FM, AM, BT etc. in my 2013 C300. Does the looper work around fix the audio for BT as well or would I need a new interface module in order to get BT back and functioning?

Interesting question. Is your Aux located in the glove compartment box?

@@Fwerks.1592 yes, the car came with the old school iPod connection 16 pin I believe and a jack both attached to one wire that came with the car. The AUX was working but I think something in the MOST engineering menu was changed but not sure if that was the cause because like I mentioned everything else I can hear fine. I was thinking it’s the MMI cable but I bought a couple and none of them worked so maybe it’s the one inside the one that was replaced in the video.

@@loraine5240 sorry for the delay, I’d have to check the c300 I have now and see what’s going on. Most definitely I can tell you that sound travels through the fiber optics, that run to the interface module, also the the infotainments in the center, Bluetooth, cd, am, fm and weather band runs to the module. If anything starts acting up it should be the module going bad.

How does a jumper work?

@Fwerks.1592

Жыл бұрын

I’m sorry for the delay! The Audio system runs in a loop! That means the light has to pass through the fiber optics and go through each module to complete the loop. So when you have a most communication issue, the ring becomes broken and the communication path becomes unusable. So here is how the bypass/ jumper comes into play. In order to confirm if a module is faulty or not you can use the bypass and plug it into the suspected bad module and you should hear sound again if that’s the problem. Once you found the break in the Most loop, you can use the fiber optic jumper / bypass connecter . What this does is basically to remove the faulty module from the network and to replace it with a connecter that “CLOSES” the loop so the light signal can continue its path. Hope this makes sense?
