AUDI A3 8P Convertible Aerial Placement

[Dave-v-v]

Hi All,
My radio signal is bad and the convertible has as no Arial on the roof, so I guess it is in the front window Has anyone got any clue before I start ripping the A and B pillars off where the booster is or the aerial?
The A3 hatch it's the boot lid and some parts in the drivers side boot cabby hole but it has a roof Arial so it is passably different?

I will get the stereo out first and have a look, as the garage had it out not so long ago and now its not as good so fingers crossed its just a lose connection.

Thanks for the help

My understanding is that the FM aerial on the Cabriolet is embedded in the windscreen and there is an amplifier (Search for part number 8P7035225A) embedded in the A-pillar. I'm guessing that aftermarket antenna adaptors don't provide power for the amplifier. I suspect what we really need is a plain cable from DIN antenna input to Fakra plug and a 1K resistor to +12V or something but no-one seems to be able to confirm this. I'm guessing the OEM radio provides power to the amplifier through the Fakra plug. (I'm having the same fight...)
