I won't be as forceful or melodramatic as my other post regarding the build quality of MB's as of late, but I will say that I am disappointed...

I picked up my car a little over two weeks ago, and the sound system (the H/K one in the entertainment package) was working well and it sounded great (aside from the occasional distortion on some songs). Today, I was driving my car in the morning and at lunch and it was doing fine and sounding great. I parked it after lunch, and then when I came back to my car a few hours later, there was no sound. I thought that the volume had just gone down, and I tried to turn it up using the steering wheel and then the main control--no luck. I next tried changing the discs in the changer--no luck. So I pulled over and turned off my car, took out the magazine from the changer and restarted my car--nothing. The radio display is there, the CD display is there, but there is absolutely no sound. When I press the CD Changer button, it now tells me "No CDC". It also sounds like the CD changer is just cycling through discs too. As for the in-dash single CD, it seems like it is playing the disc (complete with times and all), but just with no sound. Also, when I press the sound settings (the one that takes you to Bass/Treble/Surround/Standard/Speech), it no longer gives me the option of changing it to surround, standard, or speech. I have no clue what's going on. Also, correct me if I'm wrong, but now my car says "Telephone Off" on the on screen display, I thought that it used to say "No Telephone" or something to that effect.
Could it be that my system just needs to be reset? (I tried the reset in the sound settings and the fader/balance settings as well.) Or my CD changer went bad?

I'm going to take it to my dealer tomorrow and have them check it out. (Maybe I can bargain for them to put in the AUX for me since they'll already be checking out that "area".)

And, the following may seem defensive, but ever since the debacle following my last post "complaining" about MB build quality I feel that it's warranted...

For those that like to cry "ABUSE!" and blame those "punk kids." I did not abuse the sound system. I kept it at a moderate volume at all times. Nor did I keep pressing or playing with the buttons, most of the times I would just let the CD's play.

For those that like to cry "NEWB!!" Like I said in my last post, this is not my first Mercedes, nor is it my first with the upgraded sound option (I had the Bose option on my old C280 Sport), nor is it my family's first MB. I think I know what I'm doing... I just don't know what's wrong with it now.

Thanks for the help.

 

Its allright just take it in and get it fixed.

 

My '05 H/K sound system has worked properly for longer than two weeks.

It sounds like your system is confused. When the dealership connects the analyzer, there should be error codes that may indicate the source of the problem. Please post these error codes.

 

Sounds like the dealer needs to fix things ASAP! Sorry to hear that your new car is having problems like this.

Please let us know how things go.

 

Mercedes are made way better than ever, you just don't know how bad they used to be, back in the 80's. I know in my 2 W201's combined, I went to at least a dozen radios because the controls would break off in your hand. I told my parents what a POS they were but they said it's because I bought the bottom of the line so they got the E class, they had the same luck with their radios, the only difference is they paid more for their POS.

 

Ok, so I guess my car is tempermental. When I started it this morning to go to the dealer, everything was ok, the sound system sounded great, and everything was back to normal. I have no clue as to what happened. Could it have been the heat yesterday (although it was only 85 degrees)? I had it out in the sun from 9am - 3pm, and then parked it in a garage and after a couple hours it just didn't work anymore. This is just wierd. Oh well, at least I didn't have to go to the dealer anymore and everything is working fine again.

 

Even though the system is working properly, the fault codes associated with the problem should be stored in memory for a limited number of ignition cycles. There is not a down side to having the dealership interrogate the fault codes, in the event that the problem resurfaces.

 

i would hate think your brand new car is affected by the heat! even if it were 115 out, it should not.

 

hehe. sounds just like microsoft windows. just reboot the system and it will run fine again until the next system error

 

remember to always check the windows update site for repairs.

 

Haha, ok... That's what I was thinking, that's why I pulled over and turned off my car and tried to reset the radio. Apparently, a reset/reboot isn't as easy on this thing, you have to let it sit for a while...
