Poor radio reception

I Have Replaced the Radio, AMP,Coax Cables and the Reception is still crap!...Mercedes tries to BS you ..Ahh Normal
I Have Installed The W140 S Class Antenna in the rear Bumper and It Works!..Might Want to Give it a Try!

All You will need is the Coax Adapters to Connect the cable from your radio to the Antenna ...The W 140 S Class Fits in the Rear Bumper...Give it a try!
The part no is A140 8202775 which gets you a quite complex bent piece of stanless steel with a single core cable from it , I actually thought I had bought the wrong thing
It fits inside the left side of the rear bumper (viewed from the back) . you need to modify the corner piece of foam that pulls out and then secure the antenna with double sided sponge tape . you need to drill a hole for the cable to feed into the boot which is a shame but has to be done . the cabling simply is a piece of coax from the head unit to the boot area which I stripped back and connected the centre to the antenna cable and connected the coax earth to an earth mounting point inside the boot .
It is a simple and quite cheap mod to do which took me about 2 - 3 hours to do .
Thanks to Mark Cummins for the tip !

My question for synchrocnc and those others who've made the change: Did you run a new coax cable from the radio to the new antenna, or just disconnect the existing antenna cable and re-direct it? I should think it would be easier to re-direct, once you've located the correct connection. How hard was it to spot the antenna connection at the rear window?
Thanks guys!

I bought a cheap aftermarket antenna with a long cable and ran it inside the plastic cable holders with all the other cables along the inner sills , the reason for this was that I didnt want to disturb any of the original equipment so that it could be switched back if I sold the car . For your information the original coax meets the amplifier at the passenger side (RHD) so I guess drivers side in the US rear behind the "C" pillar trim .
To be honest its easier to run a new cable .
Good luck !

I can understand your reasoning regarding running a new cable. My thought was if I could find the cable from the radio near where it terminates at the rear of the car, I would have fewer trim pieces to disturb. I probably won't really be able to decide on the best course of action until I find myself wedged half-in, half-out of the trunk...er...boot.

it's possible that is the same for the w211 e class
