W245 radio problem

[uker]

My first post so please be gentle

The Audio 20 (single CD with Bluetooth telephony) in my B200 (W245, 10 plate) has suddenly lost radio signals the other day.
All the radio stations are all gone and all I get is static noises. The Bluetooth telephony still works fine.

After some searching, I've tried a few things and none of them worked...
-remove the fuse for the audio unit and re-insert
-factory reset the Audio 20
-check antenna base mounting/connections

I also bought a new compatible aerial off ebay-no luck (although I think the aerial is in poor quality).

Yesterday, I noticed that the radio managed to pick up one station for about 2 minutes when I was driving on a particular road in town. At which point I stopped the car and removed the roof antenna aerial. My logic was that if the radio disappeared then the antenna aerial must be working properly. It didn't make any difference in terms of signal strength. Later I found out that the road is close to local radio station.

The next thing I can think of is to try a new antenna base (something like the picture below. Before I spend £50 though, I'd appreciate any suggestions in terms of what else I should be looking for/trying ?

Thanks a lot

From what you say, I would be looking at the antenna or the antenna amplifier. Do they still use the rear window as the antenna? If so, you may have a loose connection and the antenna wire has come loose

Hi, thanks for your help - much appreciated.

With regards to the amplifier, Google seems to think that it's located in the 'REAR PANEL DOOR', any idea how can I access the connection and wire?

Cheers

The amplifier is located on the offside just inside the storage box. Open the lid of the storage box and then pull the internal box out, the amplifier is about 4" square fitted at the rear of the car.

Not sure, my W245 amplifier is located in the boot, just inside the rear lights on the right hand side viewed from the rear of the car. It looks very similar to what you show, but I notice your car is a left hand drive so may be laid out differently.
