I have a 2013 Mercedes Benz c300 drove around with no sound for almost 3 years! It stopped working all of a sudden the screen turned on everything you can see the radio stations AM/FM satellite, but you couldn’t hear anything. You can pair it to a Bluetooth. I could call out, but I couldn’t hear anybody on the other side. They could hear me and it was frustrating not knowing what was going on so When it happened I took it to the dealership and they told me that the amp was out basically, the exact same thing that you posted on your video happened to my vehicle THANK YOU for sharing this video it fixed my issue. I bought the fiber optic loop and went ahead and bypassed it BAM 💥 SOUND was restored. Dealer ship wanted to scam me telling me that the amp was out bs ! You keep doing what you do you are awesome 👏

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).

Hi, i found your video very useful. Unfortunately i can't get a jumper, unless i ship from US. However, a jumper simply means connecting two wires together right? Like getting a single wire with has two mouth, akd connecting them to the + and - right? And what type of jumper did you use? Name model etc

@Fwerks.1592 6 месяцев назад

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. This is called a loop, once that loop is interrupted, then you have a ring break. Here is a link to where I got mine. www.amazon.com/Universal-Optical-Adapter-Mercedes-Porsche/dp/B07PDJPXCW/ref=sr_1_1_sspa?crid=7CVVYTTLULP4&keywords=mercedes+fiber+optic+loop&qid=1706220008&sprefix=mercedes+fibe%2Caps%2C83&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

@savedbythebankrecords2831 11 месяцев назад

Having this same issue but was thinking of swapping the original head unit with an after market unit. Do you think I’d still have the same problem?

@Fwerks.1592 11 месяцев назад

Most likely yes. The most communication module controls the bluetooth audi, Aux & the volume. Remember there is a ring break, if you replace the head unit. You will still have that ring break, the loop has to be closed for everything to work properly.

I have the same model car but my issue is with the CD player, not the radio. The CD player was working fine and then one day it stopped working. I also cannot eject any of the CD's (it holds 6 CD's). If I select CD, it says "unavailable driver". Do you have any suggestions on how to fix this?? I've been trying to fix it for months and there is nothing online on how to resolve this. THANK YOU!!

@Fwerks.1592 6 месяцев назад

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.

Yo broski, I don’t have a jumper yet, ima order rn, but how can I test the amp to see if that’s the bad part? I took to audio place today and showed them your video but they don’t have jumpers and they want me to buy a 900 amp replacement

@Fwerks.1592 9 месяцев назад

You would have to disconnect the fiber optic that plugs into your amp. Connect the jumper to the fiber optic plug( not the amp). Once you jump it an if you hear sound come back, then your amp is the problem.

@Idontclockout 9 месяцев назад

@@Fwerks.1592 appreciate the response broskii I’m picking up jumper right now and will let you know! If the amp isn’t the problem, does the w205 (2017 c300) have that module under the glovebox like you showed in this video?

@Idontclockout 9 месяцев назад

Bro I took it back to the shop with the bypass and the dude swore up and down it was the amp and he refused to check the amp using bypass. I took it home and figured out how to get the trunk lining out and checked amp. ITS NOT THE AMP

@@Idontclockout I’m sorry for the delayed response. Move in the the Sirius Xm module and jump that one too. As far the most communication, since it’s a newer year I’m not certain if it will be behind the glove box. It can also be built into the head unit.

@Fwerks.1592 Год назад

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

@loraine5240 Год назад

@@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.

How does a jumper work?

@Fwerks.1592 Год назад

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?
