I have retrofitted the RNS - E on my early 2005 Audi A3. It have the Symphony concert, single DIN.
I have converted the single din cage in the centre console to a double din as required with the relevant parts.
I then bought the audio adaptor to connect the RNS E however some of the pins need re-adjusting as i get a Nav, radio and right speaker error displaying on the VCDS.
The original wires from my vehicle seems minimum compared to what comes out of the RNS E. looking carefully at the pins on both ends, either some do not meet or possible they are not correctly sitting in the right place.
The device actually works fine when connected with all speakers working i guess. The phone module also works. The reception to the radio is defo not strong as it used to be with the previous system.
So.....i need some help and advice.
Here are some pics to help you understand.

So if you can help me out i would much appreciate it.
