Changing roof antenna to black
Also, from what I can tell the antenna doesn't sell in separate components, such as the gasket, but in one complete assembly.
Doesn't seem to be a fortune.
For my car that has the triple service : teleaid/gps/satellite radio, painted to correct color it's around $350.
I'd love for someone that has one in their garage that is defective, to remove the 3 screws in the base and post pictures.
Let's see if the plastic skin separates easy from the metal base and if all the electronics are in the metal base, or are they cast into the plastic top.
Also, by googling and not using the forum search function, I found in the forum a comprehensive thread that says that the roof antenna can come out.
You're supposed to remove the rear dome light and find under it a hole where the antenna screw shows.
Then you undo that and loosens antenna.
The antenna has 3 pigtails roughly 1 foot long terminated with connectors.
Supposedly, if you pull on the antenna you may rip the cables.
Also supposedly if you replace the antenna, radio may not sound as soon as before.
Which leads me to believe that the placement of the pigtails inside the top of the headliner may be important. Maybe they have to. E positioned away from each other.
So, in that thread someone replaced the antenna without removing the headliner and someone else removed or loosened the rear headliner only.
I'm interested in replacing the skin of my antenna, so in my case, if the skin comes off and doesn't house any of the electronics, I would loosen the antenna, flip it, remove the base 3 screws and hopefully take the skin off.
Again, if anybody could show a pic of the antenna disassembled, that would be great.

it's weird that MB didn't match everything. I think I have seen a lot of cars with black gutter trim as well. and my door handles are metallic black (for hiding scratches I heard).

my antenna and gutter trim is gloss black.
OP, I would buy a cheap stick on antenna cover for like $10. Does the same job, no point in swapping it out.
Very difficult, pulling parts from under headliner, etc.

Remember, it's on the roof, so most people won't see it up close.
Even worse, trying to look for the screw towards the rear window, right at the rear edge of the opening of the dome light, begins the rear roof reinforcement bar. It looks like the rear roof reinforcement bar covers the bottom of the antenna.
So maybe reaching the antenna mounting screw through the opening for the rear dome light is only for the coupes?
I think that the antenna sits on a clip which is fastened with the screw.
So tightening the screw spreads the clip and tightens the antenna.
So, loosening the screw can allow the clip to slide up and out.
This is the only way that I can think of, where that screw can do anything, because if it's offset from the domelight opening, if you loosen it, it will just drop into the headliner and conversely, there would be no way to get it started on the threads when you try to mount the antenna, through the domelight opening.
I found now a second thread on the W204 forum where people say the screw is accessed through the domelight opening.



So, do this:
Take some light out
Move front seats up
Reach with your hand, palm up
You will be able to touch the bottom of the screw. The reinforcement has a big opening for the cables and screw.
Now, I need you to check with your replacement antenna and tell me what size Torx this is, so I can put a tool together, I'll post what I came up with.

I was able to loosen the antenna.
The screw must come out for the antenna to tilt somewhat, to be able to see the underside.
There was a lot of dirt under the antenna, I managed to clean it.
When the antenna let go, it seemed to come out gradually, like if it had silicone, but unfortunately it's dark and I'm tired, so couldn't tell whether there was silicone under, or over the gasket.
However, I just used windex to clean under the antenna and there was no silicone residue.Must have been the compressed rubber gasket releasing gradually.
Getting that screw back into the threads, through the domelight opening and getting it to catch on the threads took good 15 minutes.
I checked the antenna, seems like the radio and the GPS work just fine.
It seems like one of the connectors is within 3 inches of the antenna. Can't tell where the second is.
Once the antenna is tilting loose, I can see how you have to work with a lot of care, to avoid yanking the cables. But it doesn't seem to be that difficult.
For me it probably will be a matter of doing one screw at the time, then a 5 minute break, so that I don't get impatient and start pulling to make myself more room.

wow! Thank you man. I need to buy that tool. How much slack was there to pull the antenna out?
