Help! MM Radio (No Pwr. No Blown fuses) W204
I have done a quick search and nada! The command unit has no power (from what I can tell)
Radio worked yesterday but today no power.
Here’s the info;
* My question is:
1. Can anyone tell me how to open monitor hatch with no power? (Yes, I have pushed the buttons)
2. What fuse & where is it for the command unit, since I can't find any blown? ...I believe its 11 & 26? ...I have no literature confirm.
I know how to remove the command unit.
Thanks for any help and insight!

- I have VIM installed.
- Radio/Command has no background lights on.
- ESP, hazard, heated seats and rear shade all work & have background lighting.
- I Checked fuses in front and trunk (no passenger fuse box) and found no blown fuses.

although i haven't tried it myself, i think you can remove upper vent without opening the screen.
because i used flat head screw driver from each side of vent to remove it. I don't think there was anything under the screen cover stopping removing vent.

Negative. The screen door needs to be open in order to remove the air vent. I wish there was a way to manually open the door.
VaderSS, this should hopefully help you out:

The fuse box is located in the back of the engine bay, driver's side (Left Hand Drive vehicles). Unclip the 2 clips and open the cover to expose your fuses.
BTW, my COMAND unit decided to not wake up today either, so I yanked & reseated the fuses. It's OK now. This is the second time this has happened to me (first time it came back spontaneously after 2 hours). I really hate electrical gremlins.
The real question is... has this phenomenon happened to anyone who doesn't have the MidCityEngineering VIM Module installed? I don't think the VIM is the cause, although all the reports I've read about this phenomenon happened to people with a VIM Module (nyself included).

Hey Rick!
Funny yours did the same thing today! Turn back the clock issues? I wouldn’t know I live in Hawaii, we don’t reset the clocks.
Yup, I looked at that/my post as well, even looked at all the fuses. I printed out the pics (Rob @ Mid-City and your tuck-away pic of the VIM & T-harness). I’ll pull the fuses in the morning and see if that helps.
I thought the module was suspect but no stats to back it up.
Bigbodybeeenz on the C63 forum also had this happen and he has the VIM as well https://mbworld.org/forums/showthrea...47#post3148247
Is this happening to just us with the VIM?
Anyone else this happen to?

Rick... Guess what, it worked this morning when I moved it to get my Porsche out!
That sucks because I really wanted the patient to be sick so I could find the problem.
Chalk one up for the electronic gremlin!

I just installed VIM from midcity last weekend. So far command unit still working, but I noticed right after installing VIM that there is sometimes a delay of a few seconds from when power is turned on to the MM screen opening up. Before VIM, ther was no delay. This makes me suspect VIM causing a temporary delay in the command unit boot up. It is intermittent, and could last seconds in my case, to hours in the other reported cases. So far, the problem has been temporary but I am worried it could become permanent malfunction. Are there any ideas if the VIM is causing these glitches?

^^^No delay here. Interesting...
Yeah... electronic gremlins live in my other car too. Gotta love German engineering. Keeps you on your toes.
Glad everything sorted itself out.

its a hidden timer I put in to keep you guys on you toes... just kidding..
Im looking into this just to be sure. I have heard of this happening in four cases out of several hundred units we have fielded and one of those was a confirmed issue with command unit itself where the dealer ended up replacing the unit under warranty. Nevertheless we always keep an eye on these situations just to make sure that we arent missing anything. A good example of this would be a small production change in hardware or software that affects a very small percentage of a particular model; MB has done this a few times with the W204 already and normally we catch them because we continuously test our interfaces on new deliveries but ocassionally the do slip one by us...
At any rate we do support our products 100% so if we do need to make a firmware change to our interface we'll ship you out an advanced replacement so you theres no sending stuff in and waiting for it to come back.

I am thinking of getting MidCity's VIM, but I'm concerned about the problem explained in this thread. Have you guys experienced it again, or was it a one-time problem?? Was there a final solution other than resetting the fuses everytime it happens? Thanks!

This issue has happened about twice since the last time I posted (this is a daily driven car). It seems to correct itself after a couple of hours, and no fuses were needed to be pulled to reset it.

it really doesn't have anything to do with the VIM. mine did that before i put the VIM in. its' happened once. and sometimes mine starts up slow. but it's not something i wouldn't have expected on a german car.

On a second note...when things go wrong, specially costly things such as a MM unit..why bother messing with it yourself and voiding the warranty?

i have an 08 w204 with base audio...no nav just the 6-cd, radio and manual audio hatch with stationary display. the unit shut off three days ago. it has happened once before but powered back on in a couple of hours. i checked and reset fuses 26 and 84 per the fuse diagram but i have not done the same to 11 assuming it is there, as central display may mean something different.
i read the unit itself has a fuse in it that can blow and can be replaced by pulling the unit. is this a true statement if anyone has experience with it?

This has nothing to do with the VIM. I had the same problem where the radio would turn on one day and then wouldn't turn on for a couple of days. Did this for about a week until it wouldn't turn on at all. Took the car to Short Circuit in San Jose and for $80x2 ($80 to remove and $80 to re-install), they took out the radio without messing with the VIM (not sure and really didn't care) and provided free troubleshooting. Turns out the power supply was bad and the motherboard also had issues. They replaced both and now the radio works. However, because the newest version of the motherboard did not include the Sat Radio and Media Interface as standard options, they are still messing about with it. But suffice it to say, radio not coming on and VIM not opening has nothing to do with the VIM and everything to do with the radio because the VIM gets it power from the radio.
Just a note - seems like a lot of Mercedes Benz have radio problems regardless of model or year, really a bummer for cars that are not cheap in price but lately cheap in quality.

I don't know about that. This thread is like 10 1/2 years old with 20 posts and not all of them had the radio issues. The last two were posted in 2013 and 2016. I would hardly call that a lot of problems considering the hundreds of thousands of W204s sold in that time. Even then, it might not have even been for a quaility issue from the factory. Now if you were talking about the steering interlock.........................

Pop up screen issues
I have a 2011 c63 amg.
Anyone had issues where the screen will go up & down when it wants? It star when the screen would open half way and then stop. I’d have to keep pushing the open/close button to get it open.. sometimes it doesn’t go down either.
Is it a a fuse or the screen?

2013 C250, Same Issue
Hey guys, I have a 2013 C250 here with stationary screen. There is no power to the Comand or the radio. No blown fuses that I can find. Attempting a soft reset now for the second time. Next option seems to be to pulling the unit. Have there been any new successful attempt to fix this issue?
