I have my a D3 installed in my 2003 c230 sport coupe and have had it in for a few months now. my problem is that the radio reception is and always has been horrible. i know for a fact that i installed it as the manual suggested, but i was just wondering if anyone else encountered this problem. or if anyone has any suggestions on how to fix it.

i get some stations... but its never clear, and signal goes in and out. its absolutely horrible. i want my radio back!

any advice is appreciated.

thanks!

What did you use for an antenna adaptor?

haha... good question. i picked out the wiring harness and the faceplate/adapter thing.... but my friend got he the antenna adapter, so i'm not sure. i will have to ask him.

is there a particular one that i should have gotten?

Depends on the plug. If it's like most of the mercedes I've worked on the one you need is a 40-vw53. IT's an amplifried adaptor. The blue wire on it goes to the blue wire of the avic. That could be the cause of your lack of decent reception.

thanks... i will look into the exact model of the adapter.

my model mercedes is very standard. all the c-class sedans/coupe headunits are the same from 02-04 and thats what i have.

i appreciate the quick response! and will let you know once i find out if that fixes it. thanks!

Then it "should" be that adaptor. You're antenna is in the rear glass right. It's not a regular whip style antenna.

yes... it is built into the rear hatch.

i just read that this is for the "roof antenna". so it looks like its the one. fak! its such a pain to put in one plug.

off topic: i've been looking into rear cameras and wondering what you would recommend.

here is one that caught my eye:

but i dont know how the quality/performance is.

any recommendations?

I'd pm paisannyc about that camera. Looks like the same one I put in his expy.

Yeah if it's on the roof too, you'll need that adaptor.Always forget about that part.

Hi, I've the same problem on my C Class. I searched on internet for the 40-vw53 adapter but I didn't see Mercedes Class C in the compatibility list. Have you tried it ?

I found this one : http://www.audiooutfitter.com/40vw12/metra/p69761.html Metra 40VW12 but I don't think it's an amplified adapter. I don't know if the reception will be better.
