That WON'T solve it .... as I already said ALL RNS-E versions of ALL YEARS need the SAME antenna signals - HF & ZF.So another way to solve my problem is to change RNS-E unit that is compotable with my amplifier and rear screen, it's regarding to PR codes of the parts.
It doesn't matter if it's an RNS-E from 2004 (8E0 035 192 C) or from 2010 (8P0 035 193 C) - the antenna signals they need are the same. I know from personal experience that is TRUE, since I've had both those models fitted into my 2006 RS4 (and an 8E0 035 192 H in between them).
So changing the RNS-E in your car will achieve precisely .... NOTHING.
As already said to solve the antenna fault problem you must buy and fit the ANTENNA AMPLIFIERS that would have been fitted to YOUR car (model AND year) if it had been fitted with an RNS-E at the factory.
To repeat, changing the RNS-E in your car will achieve precisely .... NOTHING.
