Hi, installed a RNS-D unit into my 2001 Audi S3 but got a few little problems. The navigation system is in another country and wont let me enter in a UK address or post code. The voice say something like im not in the digitizes network. Also when I put VAG COM on the unit, it say in the coding invalid message. I get a fault code saying no vehicle speed signal and no communication with instrument cluster which I think is to do with the Gala wiring. Also get a little box come up every time the unit is switched on ( RDS-TMC Tuner could not be established). I dont know which wires to change to get the Gala wire connected up. Any help would be great thanks Nathan
