Hey everyone,
My 2015 C300 Stereo stopped working today. It keeps saying Please wait... and never changes. All sound features are not working(Bluetooth, phone, radio, aux). Rear view camera is delayed but does come on eventually. Any one know how to fix this or reboot this glitch?
Thx

Tried that? Any other ideas to reset this thing?

thats weird ours both malfunctioned the same day. I stopped by dealership briefly and they took a look at it. They said they have never seen that before. So I got to drop it off with them Monday. Let me know how yours goes.

Mine started yesterday too. Saw this thread at work, got into the car to go home and instantly had the same problem.

Yeah I also have a 2015 c300. This sucks I can't listen to songs. Keep this thread updated I want to know what happened with all you guys. I have take my car in on Monday let's see what happens.

The list grows. I hope we all get this settled.

Just got back from dealer. He had a line of cars with the same problem, they tried reset it with no luck and then tried to update command would crash halfway while updating. Spent 4 hours with no luck. My system is like half insaltalled now no nav or sat radio is even showing up and half the stuff from the menus is not their. That could be I guess due to the partial update but who knows. They said will give me a call in aroumd two days when I'll have to bring it in again.

Their was 5 cars ahead of me with same issue.
I don't think they know what is going on, like a virus planted to go off in a certain amount of days.
So no music nav or anything untill MB can get this fixed.

I was not made aware of this that they know.

Add me to the list. All was well Saturday morning when I drove to work then when I got in to drive home it was locked up on one radio station and no change since. I went as far as pulling the battery and some fuses with no change.

My 15 has 59k miles so no warranty left for me. I’ll be keeping track of this thread. I just left a message for my service advisor but something tells me they’ve seen a lot of these today based on this thread.

No subscription here. Never been activated in the year and a half I’ve owned the car.

I spoke to customer care on my way home tonight. They said at 8PM they received an update from the tech team that a fix had been made and it will be rolled out to all the cars by Thursday afternoon. No need to take it into the dealership as it will be sent directly to the car. We'll see..

Do we have any person fixed it yet? I was driving haft day without update from OTA.

Same issue here, talked to MB of San Antonio and still don’t have a fix...

Same issue. 2015 c300. I was assured by Mercedes USA that it was being resolved today with an update. Nothing happened. Called back and was told the update failed. It’s been a long week listening to one radio station and no phone hands free. Should have bought a Ford!

Funny thing is I had a 2012 Ford Focus before I got Benz in October and it too got ****ed up by Sirius update. I think it interrupted somehow and the whole ford stereo glitched out. BUT unlike the Mercedes it was able to fix itself after a few hiccups (better software programming I guess, I bet it’s simpler but still). Basically Sirius xm is really to blame. And after both of these experiences with Sirius I think I’m done with them.

I blame both of them. How do they push updates without testing them. I still have no solution and MB has not even made a official statement to the problem. At least give a time period that they will fix within or freaking just replace the systems or better yet if they are known to mess up just upgrade everyone’s system. I thought MB stood for quality but the cheaper cars are doing a better job currently. Sad

So they wiped my system when updating and trying to fix it. I have nothing currently in the car. The Navi audio Bluetooth and half the options that used to be in the menus are not their anymore.

we need to somehow get a statement across to MB and make sure it gets highlighted so actions cal be taken and not just the owners get taken for a ride.
i don’t even know what people out of warranty will do.

Not that this helps but it looks like MB is not alone with recent Sirius updates..

I just wanted to say that mine is also currently useless.
Audio 20 ‘base’ (w/Burmester), no Sirius subscription.

man if that works I’ll give my dealer a call tommorow
I’ll live without sat radio until they get a real fix

Anyone know how to disconnect the Sat radio?

my dealer just said he knew that fix but even with that the success rate is very low and he said the system eventually loops back so it’s not worth even doing.
now if that is true or not is another question.

So, to circle back, if we can reconnect our phones via Bluetooth, that means an OTA went through, and it still might not work, BUT, if we can convince the dealer to disconnect the SAT module, it will (sans Sirius - which sucks anyway)?

This was the last straw for me. I’ve put $ down on a 2018 Golf R. It was what I wanted to get back in 2015 anyway (wasn’t available ANYWHERE at the time). I traded my 2011 GTI in on the C400, and I’ve always had a pang of regret for not waiting it out for the R. The new 2018 is absolutely amazing, and comes with far more equipment than my C400 has in it - and a functional stereo that doesn’t suck even when it works.

I’ve had my car in the shop more times than I’ve ever had any other car previously.
It’s an absolute rocket, and really nice to be in, but with SO many issues, I’m going to bow out and get back into a VW for a while. I’ve still got my eyes on an S Class in the near future, but the 2015 W205 has been nothing but problems for me. AT LEAST 10 trips to the dealer for overnight or longer (sometimes a week or more) repairs that I can recall, I’m sure there are more that I’m simply forgetting because there are so many.

So. If I can get it to work, fantastic. The VW dealer talked to MBUSA and understand that it’s a widespread issue with the radio and just don’t really care all that much. Until the R is in my hands, I’ll continue to drive with my AirPods... *sigh*

edit: oh, and the R is both quicker, and comes standard with CarPlay :y

I am bringing mines in tommorow to have my sat module disabled, I will get access to my command but will lose sat radio until they come out with a fix. I think I can live with that.
MB could have done that from the beginning and they tried not to.
And still no official announcement of any news from MB that I know off.
we need to get this trending on Twitter

just went to MB and they tried to update system and they were supposed to do a workaround and two hours later I get car back no fix saying can’t do the workaround because they are out of the part.
great wasted my time.

i can do the workaround myself but I do not want to mess with the warranty. Not very hard. This is bull crap on MB.

I am also in Seattle have a 2015 C400 too, but I haven’t been affected by this issue so far, hoping it stays that way.

has anyone had theirs fixed?
My mb is saying their is no fix as of now.

just talked to a diffrent dealer they said bring it in. No more going to my dealer.

Called my Chicago dealer. They said they were told their particular location still doesn’t have a fix. Which doesn’t make much sense to me how this OTA update who differ so much that no fix is available for Chicago. She claimed other locations had a temporary fix.

I think the dealers are just backed up with all the cars they have to fix. They are just delaying people so the ones who are aggressive are getting their cars looked at fist. My guy at MB said he has no fix, I called another dealer they gave me a time and said it will take 30 mins. So now I am waiting at diffrent dealer, hopefully they will have it fixed as updated also.

Its a push update not OTA by the way so they actually have to plug and do it.

So at mb talked to my guy he has confirmed that the real fix is not just avaliable and only the temp fix is their. The person on the phone just made an error and actually mentioned yes they have a fix but it's a temp workaround. So my MB guy was Correct.

Ya I see what you mean. I didn’t get an appointment until the third place I called. They said they have a fix and will apply it, so we’ll see. Unfortunately not until Tuesday.

The latest fix did not work. I am currently at the dealer and they just informed me I have no sound now. They applied the latest update. I am the 2nd car with the same issue today. Temp fix doesn’t even work now either after latest update.

mine has been down since 3/15/18. They said that they'd notify me when there was a fix.
It is pretty frustrating NOT having a radio or GPS ... two of my favorite toys.

I firmly believe that this will become a class action suit.
my radio and Nav have been down since 3/15/18. This is unacceptable.

Yours has really been repaired and it worked through he weekend?
I'll call them, AGAIN, in the morning.

I called the dealer. He said that they updated one car and that
1) it didn't repair the radio/gps issue
2) their backup cam went down, too.
Told me to wait.

this is very frustrating.

My dealer is saying it was a Sirius update to their programming done over the air. As of today still no fix from MB. Has anyone got a fix yet???

Lovely. This continues to be a mess.
my other car is an Acura. I've had Acuras for 30 years and never had service issues like this.

Good news guys! Chicago location, permanent fix worked! Have all functionality including satellite radio. EXCEPT was charged nearly $350 because out of 50,000 mile warranty. Calling MBUSA tomorrow to see if they can help.

I have an appointment, w/ a loaner, to repair mine on Wednesday. They say 4+ hours to do the job.
I'll report back when the work is complete.

Got mine fixed this morning. It took 3 hours. All is well.
Radio stations and previous Nav locations are still in memory.

Called MBUSA. The Chicago service center was very helpful in working with them and getting me a reimbursement. They paid for the whole thing. Needless to say, happy ending to an ugly story.

Is it just me or has anyone noticed the sound quality dropped with the update? The bass and tones don’t sound the same to me. Maybe it’s all in my head, wanted to see if anyone else noticed this.
