@paolo_audi is in Italy, so maybe build standards differed in mainland Europe?Looking at a list of 2003 A2 options, all radio options had an extra cost, except the active speaker system. So it was possible to purchase an A2 without an Audi CD/tape/option. My 2001 1.2Tdi had no diversity unit, at least not in the "normal" place; when I bought it in 2007, it was fitted with a Panasonic radio which was most likely original.

Yes there are around four different set ups and I have only ever seen this one once before. But the diversity unity must be there somewhere. It needs that to convert the
PiI think that cars that born without radio have a different setup that cars native with radio. My a2 has been built only with front speakers and antenna connection but any radio.
I want to add one more info that might be useful. I have seen that central upper parts ( three rows ) of heated rear windows dont work. Could this problem be related to the poor fm signal ?
Sorry I am not an electrics man. I have no idea how the rear screen heater is earthed but I did read the aerial amplifiers are earthed through the metal of the tailgate itself. I would test by using a jump lead with crocodile clips from any shiny metal point on the lid, you may have to remove the the interior lower boot lid trim, and the other end directly on the battery earth. Are the rear number lights working/dim?@Andrew from where you suggest to make this test ? From heater ground pin ?

Good Afternoon Mac,I believe the lower section is the antenna only, and not part of the rear screen heater. Only the upper section is heated.
I'm guessing there is no antenna amplifier in your version, so, adding an aftermarket amp at the radio end (will need 12 V supply)
