AudiA4B6,
Alright, thanks for the clarification. I am currently buying all the parts to put the RNS-E in my 2001 B5 S4 and this was one of my issues before purchasing the N.A. version (A6 of course). As far as the difference between EU and the NA RNS-E, is there any wiring or circuitry differences? Have you heard of any on your german forums you spoke of previously? I am under the impression that all of the RNS-E units have the same wiring and circuitry and most likely programming. The only difference being the faceplate. The way the vag coding is designed, is to run a certain program (send and recieve signals) based on that code you input. Say for example you had an A4 RNS-E, in the vag coding you input the A6 code, it would then look for the GALA signal (acting like an A6 version) instead of the speed signal over CAN. Please correct me if I am wrong.
