Finally i have finished the installation just som minor things to fix before it is al good to show here. So what is done, well, i mounted a RNS-E into a Seat Leon Cupra R and al things work.
BUT... I am getting to Fault codes of the Navigation, se below:

00858 - Connection; Radio ZF Output to Antenna Amplifier

011 - Open Circuit


01317 - Control Module in Instrument Cluster (J285)

008 - Implausible Signal

Could you tell me what i am missing in my car that is making this two error´s to appear?

The CAN bus protocols are different between the various VAG brands. A device which expects an Audi CAN protocol (e.g. the RNS-E) won't work with any of the other brands. The early CAN bus devices (like the RNS-D) did not talk to much to the rest of the car or were even 3-wire (and not CAN), this is the reason why some managed to get the RNS-D installed in a VW, Skoda or Seat. But the newer devices will most likely expect certain signals using a supported CAN protocol. That's IMHO the reason why you get the instrument cluster error.

The other error is from the diversity antenna (ZF) which is most likely not connected in your car (because you don't have the Audi diversity receiver?).

The diversity antenna is not connected, correct. Bye the way, what is the diversity antenna for? So none of this faults are indicating that something is wrong with my unit/connection in my car, correct? And will this make the car ECU generate any kind of safe mode as it can do when it findes a fault code in the engine?
Thanks,

Your car should work fine but the RNS-E will not have good or any FM reception.

The diversity signal is a signal produced by the diversity box which takes up to 4 antennas and compiles the main (HF) and intermediate (ZF) signal. Without the ZF signal the RNS-E (as well as Symphony) will not properly tune into FM stations.
