A couple of weeks ago, I had a new shifter installed in my 2002 C240. The next day, I realized the sound system wasn't working. The radio has power, lights on, can change stations, but no sound.
I took my car back to the shop. Initially, they said there was no correlation between their work and the radio but agreed to check it out. So, I waited an hour then was told, nope, had nothing to do with their repair.
So, I'm looking for some guidance. Do amps just die while your car is waiting for a new shifter?
Is this just a cruel coincidence?
I have looked at videos about pulling out the radio on this car and I'd rather have a root canal that attempt that goat rodeo.
Any pearls of wisdom would be most appreciated.
Thanks.

Do you have BOSE?
If they messed up the DB2 optical cables you won't any sound.
You will need to take the dash apart to see what they f'd up.
It's not hard but there's little hidden clips etc. so very likely you
will find a Youtube video or something.
You already asked in an earlier thread. Did you look into the back behind the radio and check the connectors as I had suggested there?
Please stop asking the same question multiple times in multiple threads - it just clogs up the forum.
The radio has nothing to do with the fibre network. The (electrical, not optical) speaker wires connect directly into the back of the radio (head unit).
I'm not sure where the speaker wires get routed. It's possible they pass by the transmission hump, but don't know for sure. I'd start looking there, or you're looking at pulling the radio unfortunately.
If you had noticed the radio not working the day you picked up the car, then you'd have a smoking gun. Unfortunately because of the delay, this could be coincidence.

The speakers still have to plug into something electrically. I'm thinking the electrical system is unplugged or damaged, or OP should be able to hear *something* from the speakers.

BOSE uses optical db2 ring l for sound transmission.
And while, yes, I am certain they also need power, I know from experience replacing shifter twice and getting a few from the pick pull. that those orange optical cables run right through that area and and could get damaged or disconnected. Power to the system is provided elsewhere. Standard radio would not effected in this repair for any logical reason. Only the center console needs to be removed and nothing to do with radio unless it's BOSE.. Not sure about later Harmon Cardin probably the same.

Thank you for your input.
The speakers behind the the rear seat say Bose, so I guess it is.
AAMCO claims they did nothing wrong and the repair was not related to the loss of sound. I have looked at videos re: opening up the entire console and that is waaay beyond my comfort zone. A prior poster mentioned "looking behind the radio" but I have no idea how to do that. Everything seems to be locked tight to the center console area. Having said that, what do you recommend I do?
Who can fix this? What kind of shop?
I contacted the owner of the franchise when I was still dealing with the shifter and got no where.
I then contacted their customer service center in PA and they were essentially, useless.
Then I did some research and determined AAMCO is owned by Icahn Automotive. As in, Carl Icahn. Yeah, that guy.
I don't want to deal with AAMCO right now. I'll save that for later.
Again, thanks for listening. Any advice is so appreciated!
They might've snapped a FO cable or something. Can you get any sound out of the speakers in any mode at all?
Photos are huge, sorryThis is what radio looks like. No sound at all.
I saw another post questioning if the owner had tried the mute button on the steering wheel. If I have one, don't know how to access.
I'm going to feel like a dolt if there are settings to restore sound and I haven't been able to figure it out.

Really it's no big, so you're the same person who had the shifter issue.
DIY docs are in this thread https://mbworld.org/forums/c-class-w...314-p0705.html
Trust me it's not that hard.
Honestly I think all you need is a screwdriver and a socket wrench.
But seriously the shop DID mess it up and it is their responsibility.
There are these thin orange cables that are actually optical cables that run through that area, and
if they dislodged a connection on one or kinked one the audio won't get transmitted.
Here's what they look like, they it will not be in a loop like the picture. But orange.
It's called a DB2 ring and it controls the radio, cd changer, the bose audio and some other things.
